    This project builds every public-facing piece of a new education venture: the visual identity, the persuasive website copy, and a fully-functional mobile application. Everything must feel cohesive, modern, and geared toward students and instructors alike. Logo & Brand • A clean, memorable mark that works at small sizes, delivered in vector (AI, SVG, PDF) plus PNGs. • Complete colour palette and basic usage guidelines so future materials stay consistent. Website Copy The site will launch with roughly six pages—Home, Courses, About, Blog, FAQ, and Contact. I need engaging, SEO-friendly writing that clearly explains our mission, outlines course benefits, and motivates sign-ups without jargon.

    I’m ready to launch a dedicated online store for my sunglasses and street-style apparel line and need a full-featured website to make it happen. The site must be built as an e-commerce storefront, but with customer reviews taking centre stage so buyers can rate products, post photos, and sort feedback by style, fit, and quality. Although the first milestone is the web experience, I do want the architecture to be future-proof: please structure the database, APIs, and authentication so we can plug in a native iOS shopping app later without rewriting the back end. Key requirements • Modern, mobile-responsive website that loads fast and converts. • Secure checkout with major cards, Apple Pay, PayPal, and a simple returns flow. • Review engine (star ratings, image...

    I want to recreate the pick-up-and-play magic of Soccer Superstar, but in the pool. The core loop is exactly the same: swipe to pass and shoot, clear short level scenarios, and advance through seasons. The difference is the sport—water polo instead of soccer—and the business model: no micro-transactions at all. Revenue and optional advantages come only from rewarded ads (for example, watching a spot grants an extra attempt at a tricky move or a retry on a multi staged level). Game structure • Level-based progression: each cleared scenario advances the player through a club season, four seasons culminate in an Olympic tournament, then the cycle repeats with higher difficulty. With the difficulty reseting after 12 seasons and becoming a continuous loop • Challenges ...

    I need a brand-new Shopify store built from the ground up to sell physical consumer products. The product category, final product details and commercial positioning are confidential and will be provided later if required. For now, I need a polished, premium Shopify store structure built around strong design, mobile-first shopping, pre-launch email capture and flexible product pages. The look and feel should be modern, clean, premium and editorial, with strong visuals, clean lines, generous spacing and a high-trust consumer brand feel. It should not look like a generic dropshipping store or basic Shopify template. Reference sites for visual direction and quality benchmark: • • • • • These are references for design quality, layout, product storytelling, mobi...

    Unity Android Developer Needed to Fix and Republish an APP on Google Play I need an experienced Unity Android developer to update and republish a birdsong app, an existing bioacoustics application removed from Google Play because its current Unity build contains a reported security vulnerability associated with CVE-2025-59489. The developer must upgrade the complete Unity project to an officially patched stable version, update packages and plugins, resolve compatibility issues, perform a clean rebuild, target Android 16/API 36, ensure 16 KB memory-page compatibility, create a signed AAB with a higher version code, and assist with Google Play resubmission.

    My Android app is already live on the Play Store and now I need an experienced Google Ads specialist who can use your own fully verified ad account to drive fresh installs. The sole KPI is to maximize app installs; engagement and brand visibility are welcome side benefits, but installs are what I will measure success by. The target profile is a broad, general-audience user base, though I will supply a shortlist of specific countries to focus on so the campaign stays relevant and cost-effective. I expect you to handle the entire workflow: campaign setup (preferably Universal App Campaigns), creative suggestions, keyword optimisation, ongoing bid and budget adjustments, and detailed reporting pulled straight from Google Ads and the Play Console. Please be comfortable sharing transparent pe...

    Seneca Safety Partners is looking for an experienced software development team or agency to design and build Sentinel from the ground up — a greenfield SaaS product that fills a clear, underserved market gap in contractor safety. The Problem Field contractors currently run Job Hazard Analysis (JHA) and lone-worker safety monitoring as two completely separate, disconnected tools — neither one tied to the actual work order that drives the job. Safety compliance suffers because workers forget to open yet another app. The Solution Sentinel is a single integrated plug-in that attaches directly to the work order management / CMMS system the company already uses. Hazard analysis and worker safety now happen inside the job itself. Required Features • Digital JHA Workflow – m...

    I need a lightweight desktop or mobile utility that connects directly to the Spark Driver platform and instantly accepts available delivery jobs on my behalf. The sole focus is speed and reliability: the moment a qualifying offer appears, the software must grab it before other drivers can. Core requirements • Real-time monitoring of the Spark job feed with sub-second refresh intervals • Automatic acceptance of every delivery job (no ride-share or freight offers are presented in Spark, so no filtering is required) • Status feedback so I can see which orders were captured and when • Simple interface where I can start, pause, or stop the grabber at any time Nice to have • Optional filters for minimum payout or maximum distance • Notification sounds ...

    I’m looking for someone who can walk me through the entire process of getting iCloud running on my iPhone. I don’t have an Apple ID yet, so the first step will be creating that account correctly, then enabling iCloud and making sure the basic services—photos, contacts, notes, backup—are switched on and working. I’d like clear, step-by-step guidance delivered live (voice or screen-share) so I can follow along and understand what each option does. By the end, I should have: • A verified Apple ID linked to my iPhone • iCloud turned on with the core sync options configured • Automatic iCloud Backup confirmed If you have experience onboarding first-time Apple users and can explain things in plain language, I’d love to get started today.

    I’m ready to turn my tarot concept into a fully-playable mobile experience, exclusively for Android. The vision is a polished 3D look—think richly modelled cards, smooth animations, light particle effects when a card is revealed, and an intuitive touch interface that feels at home on modern phones and tablets. Core gameplay is classic tarot reading: shuffle, cut, and draw spreads with upright/reversed meanings displayed. Beyond that, I’d like subtle ambient music, a small library of card interpretations stored locally, and gentle haptic feedback on key actions. If you’re comfortable in Unity (or a comparable cross-platform 3D engine) and can handle everything from scene setup to performance optimisation, we’ll get along well. Deliverables • APK ready fo...

    I am launching an online marketplace in Arabic that connects customers with nearby service providers for household, office, and vehicle issues—think of Uber’s matching experience, but for plumbers, electricians, mechanics, carpenters, and similar trades. Phase one is a fully-functional website that will later feed our iOS and Android apps, so clean, well-documented code and a robust API layer are essential. Core experience I need you to deliver: • Customers create an account, describe their issue, and upload photos or video directly through the site. • Providers within a configurable radius see the request and submit an offer that includes price (fixed or hourly), ETA, and estimated completion time. • The site automatically compiles incoming offers in a ...
