My WordPress site needs dependable, month-to-month care so it stays current, secure, and fast. Each month you’ll step in to handle: • Content updates • Plugin management (several premium plugins require timely updates) • Security checks, including scans and hardening recommendations Typical work involves posting or revising pages/posts I supply, updating the indicated plugins after testing on a staging clone, and running a full security sweep with any fixes applied. I keep a small list of must-have plugins; you’ll document the versions and actions taken in a concise report delivered at the end of every cycle. Access is via standard wp-admin credentials and cPanel; I can provide staging space if you prefer to test updates before they go live. The arrang...

WordPress Security Expert: Deep Clean (probably) SEO Spam & Fix Elementor (30-Day Guarantee) Project Description: I am looking for a professional to perform a total deep clean of a hacked WordPress site. The site is infected with an (SEO) Spam hack that creates malicious folders and redirects. The Problem: Physical folders (e.g., /soppor/, /menu/, /om-oss/) are automatically created in the root. These correspond to URLs () that redirect to Casino/Gambling sites. The folders are recreated instantly after deletion. Unauthorized PHP files have been found in wp-content/uploads/ (subfolders: template-kids, sucuri, and custom-css-js). Elementor is currently broken with a 'Fatal Error'. Scope of Work: Eliminate Backdoor: Find and kill the process/script recreating the folder...

I’m looking for a reliable WordPress specialist who can both keep my site healthy and show me how to handle everyday tasks on my own. Your first priority will be routine maintenance: safely updating all plugins and themes, running security checks, and configuring automated backups. I don’t have a preferred toolkit, so I’ll rely on you to recommend proven solutions—think ManageWP, UpdraftPlus, iThemes Security, or anything you trust that delivers the same peace of mind. Once the technical house-keeping is in order, I’d like a short, live training session (screen-share is fine) focused on some site management. A concise PDF or video recap afterward would be perfect so I can revisit the steps later. Deliverables: • Initial audit with all plugins, themes...

Project Description I am looking for an experienced developer who can implement a solution to send POST API requests directly from an active browser session, maintaining full session integrity and security context. The requirement is to replicate browser network requests exactly as they occur in DevTools — including all dynamic headers, cookies, tokens, and Akamai-related security parameters — without triggering bot protection or security blocks. Core Requirements: API request must originate from the same opened browser session Must reuse: All request headers Session cookies CSRF tokens Authorization tokens Dynamic security tokens Akamai-related parameters Must work with protected endpoints (Akamai / Bot Manager enabled) Should avoid 403, 401, 504, or security val...

I’m looking for a specialist to run a full health-check on my Local Area Network. The priority is to verify that everything works as intended and to pinpoint any performance bottlenecks that might slow users down. Security is being handled separately, so your focus will be strictly on functionality and performance. The job involves testing end-to-end connectivity, measuring throughput and latency at peak and off-peak times, and confirming that current configurations on switches, routers, and access points align with best practices. I expect you to use industry-standard network diagnostic tools—think Wireshark, iPerf, or SolarWinds—but you’re free to bring in any utilities you trust as long as the results are clearly documented. Deliverables • A concise repo...

My goal is simple: understand everything that may be blocking visitors from turning into customers and fix it fast. I need a thorough audit that looks at SEO performance, security vulnerabilities, user experience—and frankly any other factor that could be hurting my conversion rate. You’ll dig through on-page SEO, technical SEO, backlink health, code security holes, page-speed bottlenecks, mobile usability, navigation flow, copy clarity, and micro-conversion touchpoints. From there I’m expecting a clear, prioritized action plan I can hand to my dev team or implement myself. Speed matters; I’d like the first findings within the next few days and the full report shortly after. Deliverables: • A concise executive summary that highlights critical issues affecti...

The expected deliverables include a fully functional web platform and mobile application with course management, payments (one-time and subscription), certificates, coupons, reviews, AI-powered course search (RAG system), and role-based dashboards. The developer must provide complete source code, deployment (staging and production), database setup, Stripe integration, AI embedding pipeline, documentation, and secure, production-ready architecture. The estimated timeline is 10–12 weeks, covering both web platform and mobile app development.

I have already completed the technical investigation of a recent security alert: the endpoint protection platform flagged an executable that tried to tamper with system files and phone home to an external server. I verified the hash, monitored live-system behaviour, confirmed the activity as malicious, quarantined the file and rescanned the host to ensure it is now clean. What I need next is a professionally written incident report that translates those raw findings into a clear narrative for both management and technical stakeholders. The document should outline the timeline of events, the investigation methodology, indicators of compromise, remediation actions taken, and practical recommendations to harden the environment against similar threats. Where helpful, map tactics to MITRE ATT&...

I need a robust web server configured specifically for storing and managing transaction records. The entire environment must meet recognized industry standards such as PCI DSS, so every layer—from operating system hardening to database encryption and network configuration—has to align with those controls. Here is what success looks like to me: • Provision a scalable server (cloud or on-prem, your recommendation) built for high-volume transaction data. • Implement advanced encryption at rest and in transit, with key management that satisfies PCI DSS. • Configure access controls, logging, and monitoring so audit trails are complete and tamper-proof. • Provide clear documentation of the architecture, compliance checkpoints, and any scripts or automation ...

I need a tailored set of Cloudflare WAF rules that operates as a Custom Bot Policy. The objective is straightforward: detect suspicious, automated traffic and have Cloudflare respond with a CAPTCHA challenge instead of an outright block. You’ll start by assessing my current Cloudflare configuration, then craft one or more custom WAF expressions that reliably flag bots through indicators such as abnormal request rates, header irregularities, IP reputation scores, or other signals you’ve had success with. Once matched, the rule action must be “Challenge (CAPTCHA).” Deliverables • Finalised WAF rule set added to my Cloudflare dashboard • Proof-of-concept tests showing legitimate users unaffected and bots challenged • A brief hand-over note ex...

I hold written authorization from the system owner and need an experienced ethical-hacking professional to carry out a controlled breach of our production environment. The assignment goes beyond a traditional penetration test: I want you to replicate a real-world, end-to-end intrusion scenario so we can measure how our monitoring, logging and incident-response teams react under pressure. Scope • Obtain initial access using any non-destructive vector you discover (phishing simulation, misconfigurations, credential weakness, etc.). • Laterally move, escalate privileges and demonstrate data access without altering or deleting information. • Leave tamper-proof evidence (flags) in pre-agreed directories so we can verify compromise. • Conclude with a thorough report that det...

My provider has suspended my Ubuntu VPS after flagging a hack on the web-server layer (Apache/Nginx, exact stack is in the incident report I will share once we start). At the moment I have zero hardening in place—no firewall rules, no SSL, nothing—so the attacker clearly found an easy way in. I do have a recent full backup, so you can work safely and roll back if needed. Your mission is to identify the entry point, remove any malicious code or files, close the vulnerability, and leave the server in a state that convinces the host to lift the ban. You are welcome to use tools such as fail2ban, UFW/iptables, ClamAV, rkhunter, ModSecurity, or any other utilities you normally rely on. Deliverables • Clean, uncompromised web root and services reinstated • Detailed ...

My CodeIgniter website has been running unchanged for years, yet since yesterday every attempt to sign in is rejected with the “Incorrect username/password” message—even for known-good accounts. I’m not sure whether anything on the server was updated, but I do have full cPanel, SSH, and MySQL access so you can inspect code, configuration files, and logs. Here’s what I need from you: • Identify the exact cause of the failed authentication. • Implement a clean, well-commented fix that restores normal login behaviour without breaking anything else. • Provide a brief report outlining what went wrong and what you changed. The stack is classic PHP, MySQL, and CodeIgniter. Once I confirm that users can log in again, I’ll close the job imm...

I’m looking for a skilled WordPress developer who can take my idea from a blank page to a fully functioning, responsive website.

Here’s what I have in mind so far: • A clean, modern layout that looks great on mobile and desktop • Intuitive navigation with clear calls-to-action • Solid foundation for SEO, speed, and security (caching, image optimisation, SSL) Beyond that, I’m open to your suggestions on themes, plugins, and any best-practice integrations (contact forms, social media hooks, email capture, analytics, etc.). Process wise, I’d like to: 1. Brief you on my content goals and brand style. 2. Review two or...

I’m ready to bring in a security specialist to run a thorough, manual penetration test on my live e-commerce application. Automated scanners aren’t enough for this engagement—I need human-driven testing that uncovers real-world attack paths.

We are looking for an experienced DNS and domain reputation specialist to help resolve an ongoing production issue affecting users on certain mobile networks (specifically T-Mobile). The specific error users see is: DNS_PROBE_FINISHED_NXDOMAIN Our platform is hosted on AWS (Route 53 + ALB / CloudFront). DNS is correctly configured and resolves properly on most networks (Google DNS, Quad9, etc.). Our domain reputation has already been reviewed and corrected by major security providers. However, users on T-Mobile are still experiencing DNS-based blocking or resolution issues. This appears to be related to carrier-level DNS filtering or residual reputation/security classification behavior — not core infrastructure misconfiguration. ⸻ Scope of Work • Diagnose carrier-level DNS...

I’m launching an online store and need a developer who can take the project from blank domain to a fully operational e-commerce site. The single non-negotiable requirement is a rock-solid payment gateway integration that handles multiple cards securely and passes PCI compliance checks. I’m open on platform—Shopify, WooCommerce, Magento, or any other stack you’re comfortable with—as long as the final build is stable, fast, and easy for me to manage after hand-off. Product search, filters, and customer reviews may be added in later phases, but they aren’t part of this initial scope. Deliverables • Responsive storefront with sample product catalog • Payment gateway set up, tested end-to-end in both sandbox and live modes • Admin das...

I’ve built a custom web application and it’s almost ready for production. Before the public rollout, I want a rigorous penetration test that will expose any weakness and help tighten every layer of security. The assessment must be hands-on and realistic, covering the full stack rather than a purely theoretical review. Scope My priorities are clear: • Code review – comb through the source for injection points, authentication flaws, insecure dependencies, and logic errors. • Network-level probing – map open ports, misconfigured firewalls, and potential lateral-movement paths. • Server configuration – evaluate patch levels, TLS setup, permissions, and hardening of the underlying OS and web server. Primary Goal The sole purpose is to imp...

I operate two offices and I purchased two UniFi UDM Pro, and I want them linked so that staff can reach internal resources from either location as if they were on the same LAN or to work remotely (VPN access). Nothing is in place yet, so the full security stack must be designed and deployed from scratch. Scope of work • Build and test a site-to-site VPN between the two UDM Pros for seamless remote access. • Create granular firewall rules that allow only the traffic we specify while blocking everything else. • Enable and tune UniFi’s intrusion-detection/prevention features to catch unwanted activity without flooding us with false alarms. • Document every setting—screenshots or exported configs—so I can replicate or restore the setup if needed. ...

I need a Godaddy-issued SSL certificate installed and fully configured on my Windows Server 2019 VPS that is also hosted with Godaddy. The certificate has already been purchased; what’s left is generating the CSR (if you prefer, I can supply one), importing the returned certs, installing the intermediate chain, and binding everything to the correct IIS site so the domain loads only over HTTPS. Once the certificate is in place, please force-redirect all HTTP traffic to HTTPS, check for mixed-content warnings, and run an SSL Labs test to confirm an “A” rating or better. Deliverables • CSR generation (or validation of my existing CSR) • SSL certificate and chain correctly installed in IIS • HTTP-to-HTTPS redirect enabled and verified • Final rep...
