What I'm looking for

I'm looking for fully remote full-time or contract work building production AI products, including LLM agents, RAG systems, evaluations, and cloud architecture, with teams that overlap US East Coast mornings or European working hours.

I build production LLM systems for real customers, including LangGraph agents, RAG platforms, and multi-LLM routing across OpenAI, Anthropic, and Gemini.

As an Independent Consultant, I own AI product delivery end to end for US and European clients. I shipped enterprise document-search and content-generation RAG backends, and raised answer accuracy by approximately 50% through evaluation-driven prompt, chunking, and re-ranking experiments.

I’ve deployed agents with tool calling, planning loops, human-in-the-loop checkpoints, persisted state, and LangSmith tracing for cost and failure analysis. I also design the cloud architecture behind these products across AWS, Azure, and GCP.

Previously, I led Node.js delivery and built scalable SaaS, payments, real-time, and event-driven systems using Python, TypeScript, React, Node.js, PostgreSQL, Kafka, and Docker. I’m available remotely for full-time or contract work with US and European teams.
