About
I’m a B.Tech graduate with a strong foundation in DSA and system design, and I’ve shipped production full-stack systems handling 1,000+ daily API requests with 99.9% uptime. Through contract work and internships, I’ve built and maintained inventory and partner-integration workflows using Node.js, Express.js, MongoDB, and React.
I also specialize in AI/LLM training and evaluation—training Anthropic’s Claude to produce production-quality code, improving reliability with Dockerfile-based validation and pytest suites. I’ve reviewed test suites to catch subtle regressions, earned a Top 1% finish in the Amazon ML Challenge 2024, and I’m now seeking remote software engineering roles.
