What I'm looking for

I'm looking to build production AI and distributed backend systems where I can own ambiguous problems from architecture through deployment, combining LLM integration, agent tooling, and scalable infrastructure.

At Faclon Labs, I build production AI and backend platforms, including a fully self-hosted RAG system for LG RDMS that uses embedding-based vector search and MongoDB document storage.

I architected a custom MCP server that exposes REST APIs as schema-defined tools, enabling a conversational agent to handle onboarding and operational workflows end to end. I also design distributed Node.js microservices across Azure and on-premises infrastructure.

I've reduced infrastructure costs by 55% through an x64-to-ARM migration, supported systems processing millions of data points daily, and built IoT systems for manufacturing visibility and airport automation.
