# Rahul Tank on Tal

## Headline

Full Stack Engineer \| Generative AI · RAG · LLM Integration · React · TypeScript · Node\.js \| 5\+ yrs shipping production apps end\-to\-end

## About

I like owning a feature from the messy first spec all the way to the part where it's live and not breaking at 2am\. For 5\+ years I've shipped production apps across healthcare, supply chain, and automotive — usually as the person who takes something ambiguous and turns it into something that works and ships on time\. A few things I'm proud of: → Sole mobile engineer on a vehicle aftersales app for 150\+ users — shipped across App Store, Play Store & Microsoft Intune → Built and owned an 8\-module dental clinic SaaS, integrating Twilio & Firebase end\-to\-end → Pushed test coverage to 90% — dropped client\-reported bugs from 4–5 a sprint to near\-zero → Cut codebase duplication from 40% to under 5% through TDD and mentoring 3 junior engineers Lately I've been building Generative\-AI products end\-to\-end — hand\-rolled SSE token streaming, RAG over pgvector, and grounded LLM output that actually says "I don't know" instead of making things up\. Same instinct as always: ship it, test it, make it reliable\. Stack: React · TypeScript · Redux · Node\.js · Express · Fastify · PostgreSQL · pgvector · Drizzle · MongoDB · Redis · AWS · Docker · React Native Open to Full Stack, AI, and Mobile Engineering roles where ownership and product quality actually matter\. If that's the kind of work you're hiring for, say hi — I'm easy to reach\.
