Golang Kafka Developers in Germany

Hi, there I’m Sergei — a backend engineer with over 6 years of experience, mainly focused on Go and microservices. Over the last year, I’ve been the sole backend developer at a high-load crypto casino project, responsible for real-time bet processing (up to 150 bets/sec), external API integrations, and system reliability. Before that, I led teams at Daribar.kz, a pharmacy aggregator, building distributed systems and third-party API sync flows. My stack: Go, PostgreSQL, MongoDB, Redis, Kafka, REST, gRPC, OAuth2. I write clean, testable code, care about fault tolerance, retries, and async communication. I can’t share GitHub due to NDA on all current and past work (even experiments), but I’ll gladly do a test task to prove my skills. Available to start right away — happy to talk further! Best, Sergei
