What I'm looking for

I want to build production-grade agentic AI systems and scalable backend platforms for startups—owning architecture end-to-end, shipping reliable microservices, and integrating LLM/RAG into real workflows.

I’m a backend engineer with 1.5+ years building AI systems and production APIs. I’m currently architecting an “agentic OS” for a Draper VC-backed biotech startup, where a LangGraph system orchestrates microservices and drives agent-controlled flask and wellplate operations across physical lab hardware through a single conversational interface.

I’ve also built a live, multi-tenant RAG SaaS platform with per-tenant vector stores (pgvector), Stripe integration, and an embeddable chatbot widget generator for client deployment. I bring strong engineering fundamentals across microservices, REST API design, and LLM application design—turning complex workflows into reliable, stream-first systems with clear validation and human-in-the-loop control.
