I'm a full-stack software developer and technical problem-solver who helps businesses build, fix, deploy, and scale their web and mobile applications — quickly, reliably, and with clear communication throughout the process. 🔧 Web Development & CMS I build and maintain custom web applications using React, Node.js, Golang, and PostgreSQL, and I'm equally comfortable working inside WordPress environments — Elementor Pro customization, WooCommerce setup, theme/plugin troubleshooting, CSS/JS fixes, page-speed optimization, and WordPress SEO. Whether it's a small fix like a broken login flow or guest access error, or a full redesign, I treat every task — big or small — with the same level of care because I know first impressions on trial tasks matter. 🔌 Integrations, Portals & APIs I regularly build custom portals and internal tools that connect to CRMs (Google Sheets, databases), automate data syncing, and eliminate manual data entry. I have experience with REST APIs, webhook-based automation, and building admin dashboards that "just work" without a client babysitting them. ⚙️ DevOps & Server Management On the infrastructure side, I manage Linux servers, configure Nginx, deploy Dockerized applications on AWS EC2 and VPS platforms like Coolify, and resolve production performance issues. I've worked on real-world problems like runaway RPC retry storms causing high CPU usage, implementing circuit breakers, exponential backoff with jitter, request cancellation (AbortController), and centralized health-state management — the kind of deep debugging that goes beyond "restart the server and hope." 📱 Mobile App Development I build cross-platform mobile apps with React Native, including AI-integrated SaaS applications, and I support Android developers with Android Studio environment configuration, emulator setup/troubleshooting, and full Google Play Store publishing — compliance checks, technical requirements, and submission walkthroughs included. 🤖 AI-Assisted Development & Automation I actively use AI coding tools (ChatGPT, Claude, Codex) to accelerate development without sacrificing code quality — but I always take full ownership of understanding, testing, integrating, and documenting whatever is delivered. I've also worked on MCP (Model Context Protocol) server builds and AI memory/retrieval systems that unify scattered conversation history into a searchable, queryable knowledge base. Why work with me: Responsive communicator across time zones (I regularly work with US, EU, and Middle East clients) Transparent about scope, timelines, and technical limitations — no overpromising Comfortable with both fixed-price trial tasks and long-term hourly engagements Deliver clean, documented, production-ready code — not just something that "works on my machine" Experience managing freelance teams, so I understand both sides of the client-freelancer relationship If you need something fixed fast, built from scratch, deployed properly, or maintained long-term — let's talk about your project and how I can help you get it done right the first time. Suggested skill tags to add: React, Node.js, PHP, WordPress, Elementor, WooCommerce, MySQL, PostgreSQL, Golang, React Native, Android Studio, Docker, AWS EC2, Nginx, API Integration, AI App Development, Google Play Store Publishing, DevOps, Circuit Breaker Patterns, Performance Optimization
