about me.

I'm a B.Tech undergraduate specializing in building scalable, multi-language frameworks and reliable infrastructure. My experience spans the full development cycle, bridging TypeScript/JavaScript interfaces with containerized backends utilizing Docker, Python, and Julia. I also have a strong foundation in DevOps and end-to-end (E2E) testing, enabling the delivery of production-ready, genuinely maintainable systems.
