  • πŸ“š Worked on retrieval and RAG systems spanning 100K+ documents and 20M+ records
  • πŸ§ͺ Built evaluation infrastructure with LLM-as-a-Judge, tool-call validation, citation checks, latency tracking and failure analysis
  • πŸ“ˆ Engineered financial data, IPO, ETF and market intelligence pipelines
  • βš™οΈ Worked across TypeScript, Node.js, Python, PostgreSQL, Redis, BullMQ, Qdrant, Pinecone and Docker
  • 🧠 Currently exploring AI agents, memory systems, agent harnesses, quant systems and backend infrastructure
  • πŸ’Ό Looking for AI Engineering, LLM Engineering, FDE and Backend/SWE opportunities
