Learning is the ongoing process of acquiring knowledge, skills, behaviors, or values through study, experience, or instruction.

Tech-Savvy and Agile Software Engineer with almost 4 years of experience specializing in Go, AWS, Terraform, Docker, Kubernetes, and CI/CD using Jenkins. Passionate about system design and driving innovation by creating efficient, scalable, and high-performance systems, leveraging Go routines and concurrency for robust, reliable solutions. Well-versed in managing distributed systems, including developing infrastructure code, building monitoring solutions, managing dashboards, DevOps, and overseeing deployments. Eager to take on leadership roles and deliver production-ready applications that align with business objectives.

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
