I've built and deployed LearnFlow AI at CCC Digital, serving 12+ active users with 99.9% uptime across 420+ API requests. I implemented RAG pipelines with LangChain, LangGraph, Groq LLM, and PGVector, alongside Express.js APIs, Prisma, JWT authentication, Vercel, and Railway deployments.
At Next Tech Lab AP, I build full-stack laboratory tools and improved MongoDB query latency by 30%. I also engineer systems projects including a non-blocking C++20 HTTP/1.1 server using epoll/kqueue/WSAPoll, and have solved 400+ algorithmic challenges.
