About

I enjoy turning real-world problems into practical, reliable web applications—and I’m most interested in the engineering behind making those applications actually work in production. I’m a Full Stack Developer with hands-on experience building and deploying web applications using Python, Flask, React, TypeScript, JavaScript, and PostgreSQL. My work covers both frontend and backend development, with practical experience in REST APIs, authentication, database design and migration, payment integration, deployment, and cross-platform application development. In my current role as a Web Developer, I’ve worked on production applications involving secure payment gateway integration with signature verification, migration from client-side storage to cloud-hosted PostgreSQL, and packaging React/TypeScript applications as native Android builds using Capacitor. I’ve also deployed and maintained a real-time messaging application and worked on Firebase push notifications across Android and Web.
