Summary
Full-Stack Developer with 3+ years of experience building responsive, high-performance web applications using React.js, Node.js, and SQL databases.
I enjoy solving real problems through software — most notably, I built Warranty Wallet to simplify warranty tracking, with the source code available on GitHub. Skilled in designing RESTful APIs, modular frontend and backend components, and efficient database schemas, with experience in Express, Vite, and Docker-based deployments.
I focus on performance, security, and user experience, while continuously improving the systems I build and the way I work.
