I already have a hosted HTML/CSS site with several sections roughed in; now I need it taken to a polished, production-ready level. The priorities are clear: refine the visual design, tighten the navigation, and reorganize the content so everything feels purposeful and professional. Beyond aesthetics, I want real functionality. Clients must be able to register, log in, browse and purchase our services—consultations, programs, and other offerings—then complete payment in one seamless flow. After checkout they should immediately upload any required documents, so an integrated file-upload step is essential. Product/service management, a shopping-cart experience, and secure payment-gateway integration all need to sit on top of the existing codebase without starting over. Curre...

Our production Android app is stable in the market, but I now need a rapid, one-month push to get the entire platform ready for a broader launch .The existing codebase will be shared the moment we agree on the scope, after which I need you to work end-to-end across web services and mobile. Here is what has to happen during the sprint: • Backend upgrades – Refactor database management for speed and reliability – Tighten user authentication flows and token handling – Clean up and extend API interactions so both mobile clients consume a single, consistent layer – Add real-time notifications (push and in-app), advanced analytics collection, and payment processing • Front-end polish on the current Android build – Refresh the user in...

I need a fully-featured mobile app published on both Google Play and the App Store so my patients can reach me easily and securely. The core experience is a private messaging channel between each patient and myself, backed by phone-number authentication with a one-time password flow (no email or social log-ins). Inside the chat screen patients should be able message and also start voice with a single tap. All conversations, calls, and bot interactions must remain HIPAA-compliant and encrypted in transit and at rest. I am open to the tech stack—React Native, Flutter, or native Swift/Kotlin are all fine—as long as the final build passes App Store and Play Store review guidelines. You will also set up the lightweight backend necessary for OTP verification, real-time messaging, ...

We are looking for an experienced backend developer to help us build a WhatsApp integration system using WhatsApp Business API with webhook-based communication. Currently, the WhatsApp Business setup is not providing a QR-based authentication, so the connection will need to be handled via webhook configuration and backend session handling. The main objective is to build a scalable backend system where each user can create and manage multiple WhatsApp instances, maintain persistent connections, and handle messaging events efficiently.

I am looking for a quiz system for a website that I have that will be for people to watch a YouTube video and after the video is done running they would be presented with the first question in the quiz about the content of the video. Each subsequent question would be displayed after they answer a question until they are done and it would show them their score and send me an email that this person has submitted the quiz successfully with their score. It would have a scoring system based on the number of questions asked and there would be one single correct answer from a series of three or more possible answers. I would like a method by which I can enter an email address into a table and if the person trying to take the quiz does not have an email in that table they would not be able to take...

I’m building a social-networking experience exclusively for Android and need an end-to-end developer (or team) who can take the idea from wireframes all the way to a polished release on Google Play. Here is what I expect: • Design and implement a clean, modern UI that feels native to current Android versions (Kotlin or Java is fine, Jetpack Compose welcome). • Set up the complete back-end, authentication, real-time data exchange, push notifications and analytics using tools you are most comfortable with (Firebase, AWS Amplify, custom REST—open to recommendations). • Deliver a thoroughly tested APK / AAB plus full source code and clear build instructions so I can compile future versions myself.

I need to finalize the system. It's an open-source system, so it requires a high level of expertise. Freelancers need to review the system for further discussion.

I have a series of small, rolling jobs that touch PHP, MySQL, CSS and HTML. Every few days I post a short list of 3–5 items, you look them over, place a quick bid, and—if your quote fits the lean budget I work under—I’ll hand you SSH credentials so you can jump straight into the codebase. Communication stays inside Freelancer chat; I’m online to clarify logic, database structure or front-end expectations whenever something isn’t crystal clear. Once you confirm the fixes or tweaks are finished, I’ll review on the server, release the payment for that batch, and ping you again when the next set of tasks is ready. If you’re comfortable with lightweight jobs, clear guidance and fast turnarounds, let’s start on the first task list right awa...

I’m working on a project with the AVR-IoT Cellular Mini (Sequans Monarch 2 modem), where I modified the Arduino-based firmware myself to periodically transmit GPS latitude and longitude data to my backend (BE) over HTTPS. The objective is to send GPS data (latitude, longitude, and timestamp) to a REST API endpoint at a defined interval and confirm that the data is successfully received and visible on the backend. At the moment, I’m blocked by a TLS issue while attempting to configure the CA certificate for HTTPS. When I try to add the root CA certificate (ISRG Root X1 – Let’s Encrypt) to the device/modem, I get an error that says: “CA certificate input too long” Because of this issue: • The TLS handshake fails. • The HTTPS request does no...

I am looking for a code savvy assistant to help me with my ideas. I would like to build a workflow for building tools and apps. I am interested in customizing an AI model to be a useful virtual assistant that understands my workflow and designs. I am a coder by trade, but old school, so I also want someone to teach me! I am not interested in automated bids. If you would like me to consider your bid, include human written text that is obviously written by you! Tell me something about yourself! You could really get my attention if you mention something about current events related to Magic The Gathering, The SF Giants, or DJing / Dance Music. This is the AI slop generated by my prompt I guess its ok lol: "I’m rolling up my sleeves to create “tools for building tools...

I need a complete website built first, followed by a lightweight Android utility app that complements the site’s core features. The site will serve as the public-facing hub, while the app will handle on-the-go tasks that users might prefer outside a browser. For the website, bring responsive front-end skills and a solid back-end framework of your choice; speed, clean code, and scalability matter most to me. Once the site’s foundation is stable, we will move on to the Android build. The mobile component is a pure utility tool—simple, fast, and focused on one primary function—so lean architecture and a minimal footprint are key. Deliverables • Fully deployed, production-ready website with tested APIs • Android APK (and Play Console assets) wired to...

I need a slim, login-based multi-tenant portal that lets phone repair shops handle the full life-cycle of a ticket while keeping every record synced to JetForm through its API. Core workflow A Shop Owner (with Sales and Admin roles also available) logs in with Email and Password, creates or selects a Customer, registers the Device with its IMEI, adds the replaced screen or other part, and submits a Ticket.

Backend Engineer Needed for RAG Architecture (LLM + Vector Database) --- Project Description I am looking for an experienced developer to design and implement a production-grade RAG (Retrieval-Augmented Generation) backend for a controlled knowledge system. This is not a generic chatbot project. The goal is to build a system where a language model can query a structured knowledge base while enforcing strict safety and retrieval rules.

Project: Armbrella – Fitness & Wellness Social Platform Armbrella is a mobile platform focused on fitness and wellness that combines health tracking tools, social media features, free wellness video content, and a professional search engine for users to connect with trainers and wellness professionals. The mobile application is built using React Native, while the backend services are developed using NestJS and AWS cloud infrastructure. The platform was originally built using AWS Lambda (serverless architecture), but due to performance limitations, cold start latency, and stability issues, the application experienced delays in launch readiness. We are now migrating the backend architecture from AWS Lambda to AWS EC2-based services to ensure better performance, reliability, and sca...

I have a steady stream of micro-tasks that revolve around building custom sliders and carousels for WordPress sites. For each request I will supply JPEG or PNG references plus basic instructions on what I need. Sometimes a phone call is needed. Your job is to translate that into a lean shortcode or widget written in PHP, HTML, CSS and vanilla JS (or a lightweight library we mutually agree on), enqueue it properly, and hand back a drop-in file that’s ready for production. Because these jobs are small I expect a 48-hour turnaround from the moment I deliver specs. zip with clear install notes or to make amendments to a cloned page in Live is all I need; if anything breaks in the first round of testing, I’ll ping you for an immediate patch. Knowing your way around WordPress h...

I’m working with an existing FlutterFlow template and need it fully connected to Firebase. This includes configuring Firebase Authentication, a Firestore (or Realtime) database, and Cloud Messaging so I can log users in, store data, and push notifications without errors. Once the back-end connection is solid, I’d like a few light front-end touches: update the primary colour palette to match my branding and swap specific wording in the UI—think changing every instance of “event” to “activity” and similar quick text edits. Deliverables • Firebase project configured and linked to the FlutterFlow app (Auth, Database, Cloud Messaging) • Updated colour scheme applied across all relevant screens • Text replacements completed and ver...

I have an MVP running on Java 17, Spring Boot, REST, and MySQL, and now I need it turned into a production-grade multi-vendor marketplace. The platform must expose dedicated Admin, Seller, and User dashboards, scale confidently on AWS, and remain clean and testable. Scope • Upgrade the existing product, cart, order, and payment modules so multiple sellers can manage their own catalogues independently. • Add advanced search functionality—keywords, categories, price ranges, and vendor filters—backed by Elasticsearch (or a comparable search engine) and integrated with Spring Data. • Introduce user reviews and ratings with a moderation workflow surfaced in the Admin panel. • Deliver real-time notifications for order status updates, stock alerts, and sel...

I have a single MySQL database sitting on my Hostinger account and three separate custom-built PHP sites that need to talk to it. At the moment the connection fails whenever the login page tries to authenticate a user, so I suspect the issue is buried somewhere in the backend configuration—possibly wrong credentials, hostnames, or overlooked privileges inside phpMyAdmin. Here’s what I need from you: • Inspect the current hPanel and phpMyAdmin settings, make sure the database user has the right privileges, and confirm the host names for all three sites. • Review each site’s PHP connection file, tidy up the mysqli / PDO code as required, and verify that user-authentication queries run without errors. • Test end-to-end on all three domains so logging i...

I need a professional mobile app developer who can deliver a working app. Please share your previous app work, estimated timeline, and cost.

I’m searching for someone who can comfortably switch between front-end and back-end work while also handling day-to-day bidding on freelance marketplaces for me. The development stack is flexible at this stage, so if you are equally happy working in React, Angular, Vue, Node.js, Django, Rails—or any comparable frameworks—feel free to bring your strengths to the table. Here’s what the role looks like: • Code what’s needed on both the client and server sides, from fixing small UI bugs to adding new database-driven features. • Draft, refine, and submit compelling proposals on freelance platforms, keeping an eye on suitable projects and tailoring each bid to maximise our win rate. • Provide quick progress updates so we can keep momentum and ad...

My TypeScript-based app needs a fresh set of eyes. Two problem zones keep slowing development: the user interface occasionally renders the wrong state, and the data-processing layer throws intermittent logic errors. I’d like you to trace the root causes, patch them, then reorganise the affected modules so the codebase is cleaner and easier to extend. Because the troublesome behaviour reveals details of planned features, I’ll share concrete scenarios and test cases once we have a signed NDA. After that you will have full repo access, current build scripts, and unit test coverage reports. Deliverables • Fixed UI and data-processing bugs, confirmed by our existing automated tests • Refactored, well-commented TypeScript modules that follow our linting rules • A...

I am looking for a developer to build a lightweight web-based security scanning tool that can analyze websites and detect a few common security issues. The goal of this project is to create a simple tool where a user can enter a website URL and receive a report highlighting potential security weaknesses. The application does not need to be extremely advanced. The focus is on a clean interface and detecting a few important vulnerabilities. Main Features The tool should allow the user to: • Enter a website URL to scan • Check if important HTTP security headers are present (Content-Security-Policy, X-Frame-Options, HSTS, etc.) • Detect if the site is running on HTTPS or HTTP • Identify missing security headers • Detect exposed directories such as /admin, /login, ...

I’m building a web app on Replit and deploying it on Railway. Clerk’s components already render on the site and the user can submit their credentials, but after the redirect the page never reaches the dashboard—it just sits on the loading screen and repeats the sign-in loop. There’s no visible error message in the browser; the session simply never finalises. What I need • Review my current Clerk configuration (frontend and backend keys, JWT settings, callback URLs, environment variables). • Check the Replit dev environment versus the Railway production build for any mismatched origins or missing secrets. • Correct any routing or middleware that might be blocking the session token from persisting. • Confirm that, once fixed, a successful ...

I need a web-based oddsmatcher focused solely on sports betting. The tool must pull live odds from multiple bookmakers, refresh them in real time, and present the data in a clean, responsive interface that works in any modern browser. A built-in betting calculator should instantly show potential profit or liability for matched-betting scenarios, while automated alerts—by email, browser push, or both—must notify users the moment a profitable or arbitrageable spread appears. For the back end, you will aggregate odds through official or publicly available bookmaker APIs, normalise the data, and keep latency to a minimum. The front end should be lightweight yet polished—React, Vue, or a similarly modern framework is fine so long as the UI remains intuitive on desktop and mob...

I’m ready to bring a new full-stack engineer onto the team and would like to work with someone based in Pakistan. Day to day you’ll be handling both front-end and back-end tasks, moving comfortably from interface tweaks to API design, while keeping code quality and clear communication at the heart of everything you do. You should feel confident writing clean, maintainable code, troubleshooting production issues, and explaining your decisions in straightforward English during stand-ups or chat. Whether the stack leans toward JavaScript frameworks, Python, or another modern toolset, I value solid problem-solving skills and proactive collaboration more than any single technology badge. If you’ve shipped web apps end-to-end, enjoy iterative development with frequent feedbac...

I need the core functionality of a desktop program rebuilt as a browser-based application. The application is available here: The only features that must cross over are the real-time data routines: live data updates streamed from our internal databases and on-the-fly analytics that users currently rely on for quick decision-making. Your work starts with analysing how the existing desktop code ingests, processes, and visualises data, then designing a responsive web front-end and a robust back-end that replicate the same speed and accuracy inside any modern browser. WebSocket or equivalent push technology will be essential to keep latency low. I will provide access to the current source, schema details for the internal databases, and test data. The finished web app should: • Conn...

I want visitors to open my site, create a quick account, and immediately start chatting with Grok about one very specific topic that I will preload into the model. Your job is to wire the Grok API into the site, make sure users can sign up or log in, and allow them to launch one or multiple conversation threads that stay tied to their profile. Because I haven’t locked us into a particular CMS or location for the widget, you’re free to recommend the cleanest technical path—whether that means a lightweight pop-up on every page, an embedded window on just a few sections, or something in-between. What matters is that the chat feels native, remembers the user’s context, and always answers from the custom knowledge base I provide. You’ll handle: • Secure acco...
