About

cat about.txt

I'm a full-stack developer with hands-on experience shipping real, hosted products โ€” not just prototypes. Most recently I built and deployed the production website for Technocal Instrumentations end-to-end: React front end, backend integrations, DNS and Cloudflare configuration, and post-launch maintenance.

My background spans React.js, Python/Flask, PHP, MySQL and MongoDB, with a specific interest in APIs and workflow automation โ€” I hold a Postman API Expert certification and treat API design as a first-class part of any build. I also spent time at the intersection of web development and cybersecurity, which shapes how I think about auth and data handling.

In parallel, I'm completing a B.Tech in AI & Machine Learning at Sandip University alongside a Credit Linked Program in AI/ML at IIT Guwahati, and I hold five Oracle certifications across generative AI, data science, and AI foundations. I like projects where full-stack engineering and applied AI meet.
