Hello
- I'm Subhash Jha, a full-stack software engineer based in Pune, India, specializing in TypeScript, Next.js/React, Node.js, real-time systems, and production AI (LLMs, RAG, vector search).
- I take products from concept to production with an obsession for speed and UX — creator of Spectr (privacy-first analytics with RAG-powered natural language copilot, 250k+ events tracked) and Meetly (E2EE video calls with automated LLM meeting intelligence).
- Previously at PW Skills, I engineered student learning dashboards and optimized client rendering pipelines, cutting page load times by 35%.
- Currently open to full-time software engineering opportunities, high-impact teams, and open-source collaborations.
