Uchechukwu N.
Full-Stack Eng. | React, Next.js, TypeScript, APIs, AI-Powered Apps
🚀 Need a reliable full-stack engineer who can turn product specs into real, scalable features? I’ve delivered high-quality web apps across fintech, SaaS, and healthcare. I specialize in building clean, responsive UIs with React, Next.js, and TypeScript, and integrating them with APIs and modern backend services like Firebase and PostgreSQL. Recently, I’ve also been working on AI-powered applications, with a focus on retrieval-augmented generation (RAG): Built an MVP with FastAPI, Python, React, and Vercel’s AI SDK for RAG, which won 3rd place at DEF CON 33 in the US Army’s xTechLive competition. 💡 Whether you need someone to build out a feature from scratch, clean up a legacy codebase, or collaborate with your design and product teams, I’m here to help.
