What I'm looking for

I'm looking to build and lead high-load, secure distributed systems, especially in fintech, streaming, big data, and platform engineering. I'm also seeking sponsors and experienced contributors for my open-source Orbital game-server framework.

I've led backend engineering at Codeitup (ArgoStudio), delivering high-load fintech, cloud-platform, analytics, and Kubernetes CI/CD systems in Go and Java. I manage an 11+ developer backend team and have helped win contracts supporting 42% revenue growth in 2024 and 60% in 2025.

Previously, I built payment gateways at N26 and predictive analytics data platforms at Siemens, using Kafka, Flink, Java, Python, and Go. I also maintain Orbital, an open-source distributed Java Vert.x game server for real-time multiplayer games.
