I specialize in architecting LLM-powered tools and Rerieval-Augmented Generation (RAG) pipelines that solve complex data problems. I am looking for a senior or founding role where I can build high-impact products from the ground up.

About Me: Senior Full-Stack Engineer and former Solo Founder with 10+ years of experience. I specialize in the "zero-to-one" phase—I built, scaled, and exited an EdTech SaaS where I owned the entire stack from API design to AWS infrastructure.

Currently, I’m a Team Lead at FairwAI, where I architect polyglot microservices and productionize GenAI/RAG pipelines. I’m an AI-native developer (Cursor/Claude Code/Agentic workflows) and have a deep technical interest in high-performance systems and Physical AI (robotics/drone navigation).

I thrive in high-trust, low-process environments where I can take complete ownership of a product's technical direction. Looking for Senior, Staff, or Founding Engineer roles at mission-driven startups.
