What I'm looking for

I’m seeking senior backend/cloud roles where I can design scalable, observable systems, lead technical teams, and drive reliable, high-performance production services.

I am a Senior Golang engineer with 6+ years of production Go experience building high-concurrency microservices and cloud-native systems for fintech, crypto exchanges, and enterprise SaaS across Europe and the US. I specialize in scaling services from prototype to very high RPS, Kubernetes orchestration, and observability-driven reliability.

Throughout my career I’ve led backend teams, founded and sized startup engineering efforts, and delivered mission-critical systems—introducing Go at large organisations, architecting authentication and CI/CD solutions, and improving performance to support 200k+ RPS in production. I focus on pragmatic architecture, strong testing and CI/CD practices, and measurable operational improvements.
