I help businesses build, fix, and scale modern web applications with zero downtime. Whether you need a Next.js app built cleanly from scratch, complex API integrations, or critical bugs fixed in production, I step in to move your project forward. With 7+ years of engineering experience, I leverage modern web ecosystem tools and AI-assisted workflows to ship high-quality updates faster than traditional developer setups. Most clients hire me for one of three reasons: - They need a new web app or MVP built properly from the ground up. - An existing application is broken, slow, or has an uncompleted feature backlog. - They need a reliable, independent developer who can sync with an existing team and ship clean work immediately. My Core Technical Stack: - Frontend: React, Next.js (App Router), TypeScript, Tailwind CSS - Backend & DB: Node.js, NestJS, PostgreSQL - Cloud & DevOps: AWS, Vercel, API & Payment Gateway Integrations What I bring to your project: I care deeply about clear communication, technical reliability, and solving the actual business problem, not just writing lines of code. If a requirement is unclear, I ask targeted questions before building. If I spot a more efficient architecture or a security gap, I present a clear solution. If you need a developer who takes absolute ownership, communicates transparently, and helps unblock your product, let's chat about your project.
