What I'm looking for

I'm looking for challenging programming work where I can build reliable systems, manage projects, collaborate closely with teams, and solve complex technical problems.

At Bitstamp by Robinhood, I build mission-critical crypto exchange systems for deposits, withdrawals, and Travel Rule compliance. I design scalable Django and Go microservices, event-driven Kafka workflows, Vue components, and AWS deployments.

I've also owned backend architecture and production infrastructure as an independent contractor, building Django-based data applications and contributing to Drivamo's truck-driver evaluation simulation platform.

Previously at Outbrain / Zemanta, I developed advertising platforms with Django, Angular, TypeScript, Celery, Kafka, AWS, Postgres, Redis, and Docker. I supported on-call operations, mentored new team members, reviewed code, documented projects, and worked on large data migrations.

I've co-founded a logistics platform, built truck management systems, and led medical and safe-driving simulations using Unreal Engine, SCANeR, Python, C++, C#, and Arduino. I hold a Master's degree in Electrical Engineering and enjoy solving complex problems through clear, maintainable code.
