What I Work On

Data engineering, analytics, and applied AI — from first principles to large-scale production systems.

With over 15 years in the industry, I currently work as a Principal Engineer at a leading fintech. I design and operate large-scale production data systems under real constraints — cost, reliability, compliance, and growth.

Focused, hands-on work grounded in real production experience.
