If you're looking for a developer who can take full ownership of your project — from architecture through deployment — I bring over five years of hands-on experience building scalable, production-ready web applications for growing businesses and enterprise clients alike. I work across the modern full-stack ecosystem, specializing in NestJS, TypeScript, Next.js, React, and Ruby on Rails, with strong expertise in both relational and NoSQL databases (PostgreSQL, MySQL, MongoDB). My background in Docker, Kubernetes, and AWS cloud infrastructure means the systems I build are not only functional on day one, but designed to scale as your business grows. 📌 Professional Experience Currently a Senior Software Engineer at Code Up Scale, where I architect enterprise-grade platforms for real-world industries — B2B marketplaces, facility management, healthcare, insurance, and aviation. Previously, I spent three years at Devsinc, delivering full-stack solutions across SaaS and consumer-facing products. 📌 Representative Work ✔️ Ilgos — a multi-vendor B2B e-commerce marketplace with dynamic pricing, Stripe payment processing, and real-time inventory ✔️ CAITA — a HIPAA-compliant, AI-powered mental health platform that reduced clinician documentation time by 60% ✔️ Londen Leads — a high-volume SaaS platform automating 95% of lead distribution across the UK insurance market ✔️ Masjid Nabawi Inspection App — a mission-critical facility management system used at one of Islam's holiest sites ✔️ Urgent Flights — an aviation charter marketplace with AI-driven email quote extraction and multi-leg flight logistics ✔️ Additional platforms delivered: Dromeninc, Executive Hiring, Tartle, ExpenseWise, DIBS, and Sales Engine 📌 What You Can Expect When We Work Together 🔹 Full ownership of the development lifecycle — from technical planning and system design to final deployment, minimizing the need for multiple hires or handoffs 🔹 Clean, maintainable code built with long-term scalability in mind, not just short-term functionality 🔹 Secure, well-architected systems, including authentication, role-based access control, and multi-tenant support where needed 🔹 Transparent, responsive communication at every stage of the project 🔹 Reliable delivery — I take deadlines and budgets seriously and plan accordingly 📌 Why Clients Choose to Work With Me I approach every engagement the way I would my own product — with attention to detail, a focus on solving the actual business problem, and a commitment to delivering something that works well beyond launch day. My goal isn't just to complete a task, but to build a working relationship you can rely on for future projects. If you have a project in mind, I'd welcome the opportunity to discuss your goals and how I can help you achieve them.

About Me Full-stack developer with 8 years of experience building web applications end-to-end, from architecture to deployment. My core stack is React, Next.js, and Node.js/NestJS on the backend, with SQL (PostgreSQL) and NoSQL (MongoDB) for data, Redis for caching and real-time features, and Docker for containerised deployments. I also work in WordPress and PHP for CMS-driven projects and platform migrations. What I Do ✅ Build custom web apps and APIs with React, Next.js, Node.js/NestJS, and PHP ✅ Design and customize WordPress sites, themes, and plugins to match a brand, not a template ✅ Migrate existing sites to WordPress or to a modern React/Next.js stack ✅ Optimize slow apps: database indexing, query performance, caching layers, rendering strategy (SSR/SSG/ISR) ✅ Debug and harden production systems, including real-time features (Redis Pub/Sub, WebSockets), auth flows, and microservices How I Work ✅ Clear milestones with regular progress updates ✅ Transparent, step-by-step delivery plan ✅ Clean, maintainable code over quick hacks ✅ Honest communication, no surprises at delivery ✅ Focus on understanding your actual business problem, not just the surface request If you're building something new or fixing something that's already live and needs to work better, I'd like to help. Let's talk about what you're trying to build.
