Message

At TravlrId, I work as a forward deployed engineer embedded with enterprise clients including Scania Europe. I designed an event-driven integration for enterprise travel profiles across 60+ legal entities and optimized 400-record bulk sync from about 104 seconds to 3–7 seconds.

I’m also building permission-aware RAG and LangGraph agents for travel data and support workflows, with filtering and deterministic guardrails against hallucinated traveler information. Before TravlrId, I worked on backend and Web3 products at Stabl.fi, RCT.ai, Smartchain.me, and Cryption Network.
