What I'm looking for

I’m looking for a production-focused role where I can build agentic AI end-to-end with LangGraph/RAG, resilient multi-model fallbacks, and scalable event-driven AWS—while shipping full-stack experiences that move measurable metrics.

I’m a software engineer with 3 years of production experience building agentic AI systems end-to-end—multi-agent LangGraph orchestration, RAG on pgvector, automated evaluation loops, and multi-model LLM fallbacks (OpenAI / Gemini).

I’m strong on TypeScript, Node.js, NestJS, Python, PostgreSQL, and event-driven AWS (Kafka, SQS, Lambda). In production, I own architecture through support with minimal supervision, adding per-step LLM cost/latency instrumentation and resilient delivery using retries, circuit breakers, and graceful failure recovery.

I also build full-stack products: I shipped an Electron + React streaming client with OBS/RTMP/FFmpeg fan-out and browser remote-control, and delivered a 500K-user ride-hailing backend on AWS with Kafka + SQS for real-time dispatch. As a published ML researcher (Hand Sign Recognition—200+ citations), I bring research rigor to practical, measurable outcomes.
