I'm Bharat Chejay J, a Team Lead with 8+ years of full-stack and AI engineering. I ship whole platforms: web, mobile, backend, and the Linux boxes they run on.
- 🩺 Right now: building NEET.info, an AI operating system for NEET UG and PG counseling. 22 live tools, an agentic coach on self-hosted models behind four layers of guardrails, a nightly-synced national directory of 823 medical colleges, and an Expo React Native app already on TestFlight and Play internal testing through Codemagic cloud CI, all on infrastructure I administer myself
- 🧭 Most recently: Team Lead at PartyWitty (Mar-Jul 2026); across my career I've owned up to 87% of a production backend and nearly half of all engineering commits across 10 repositories
- 🤖 Before that: 4 years building AI document-intelligence and CRM automation at Nablasol (OCR + GPT-4 pipelines at 95% accuracy, 24M-record scale) and 3.5 years of full-stack delivery at Quantum Leap, where I led the TATA management portal
- 🛠 I love building: payment systems, agentic AI pipelines (Dify RAG agents, LangChain, speech-to-text into LLM summaries), secure Linux infrastructure, and technical SEO that puts real businesses on page one of local search
- 🔐 Also shipped: SlotItUp, a full appointment-booking platform with a Play Store app, plus a zero-dependency encrypted database backup platform and a 46-point infrastructure security overhaul
