What I'm looking for

I’m looking for remote-first teams that care about how systems are built, not just whether they run, where I can build reliable production data platforms, pipelines, and LLM-based systems.

At EIT Urban Mobility, I built the organization’s first version-controlled data infrastructure and a production RAG assistant serving 200 employees through Teams.

I’ve managed 75+ Azure production pipelines at SDG Group, led three engineers, and delivered ETL workflows across enterprise systems exceeding 150 million rows. Earlier, I co-founded Urbix Analytics, building data analysis and AI tools for real estate and property management firms.

Through Temujin Labs, I ship production-grade ML and data tooling, including an observable inference platform, a federated QA system, and a PySpark code intelligence platform. I care about building systems reliably, not just making them run.
