About Me

Hey! I'm Shreyash Kolhe — a Full Stack Developer with 4+ years of experience delivering scalable React.js and Node.js applications for US enterprise clients. I've successfully shipped 11+ production applications including SPAs, backend services, and mobile apps on the App Store and Play Store.

I'm currently diving deep into Artificial Intelligence — building AI-powered solutions with LangChain, RAG pipelines, and vector databases. AI is the future, and I can't wait to combine it with my web dev skills to build something truly amazing!

I'm also a blogger here, sharing everything I learn about Full Stack development in a simple, practical, and interview-focused way.
