About Me

I'm a Senior Full-Stack & AI Engineer based in New Delhi, building production GenAI systems at Couchbase. I've shipped 4 end-to-end AI platforms serving 1M+ daily queries — from RAG-powered helpdesks to text-to-SQL via MCP to multi-LLM sales forecasting.

My stack spans the full AI product lifecycle: multi-provider LLMs (Claude, GPT-4, Gemini) with automatic fallback, Couchbase Vector Search for RAG, MCP tool-calling for secure data access, and React frontends that make it all feel simple. Previously at Oracle, where I built enterprise systems handling 10M+ daily transactions.

I hold an M.Tech from NSUT (specialized in AI and distributed systems), qualified GATE (top 5% among 200K+ candidates), and am an OCI Certified Generative AI Professional.

The model is the easy part. Everything around it — retrieval, validation, fallbacks, security — is the job.

Technologies I work with:

  • Claude API / GPT-4 / Gemini
  • RAG / Vector Search
  • React / TypeScript
  • Java / Spring Boot
  • Python / Node.js
  • AWS / Kubernetes
  • Couchbase / PostgreSQL
  • MCP / LangChain
