Golang Developers

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

⍟ Golang Development: 4+ years of hands-on experience with frameworks such as Gin, Echo, GoKit, and Beego.

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

I am a Senior Backend Engineer with over 7 years of experience building scalable, high-performance systems using Go, Kafka, PostgreSQL, and Kubernetes. I specialize in microservice architecture, event-driven design, and cloud-native development on AWS. Have led critical modernization projects at GEP Worldwide and Vimeo, and passionate about clean code, distributed systems, and mentoring engineering teams.

I'm an experienced software developer with 17 years in the industry, occupying various roles including Lead and Principal Engineer. I love programming and the process of delivering actual products to users. Over the years I've worked with various languages and stacks in a backend development context -- mostly Ruby, JavaScript and Go -- plus many others that I learned on my own time. Picking things up quickly and learning a new development stack is something I enjoy. As Lead and Principal Engineers in companies I've been responsible for tech teams of up to 40 devs, leading technology choices and designing high-level solutions to be implemented by the team. I'm looking for a more hands-on programming job down in the trenches, although my expertise with company-level decisions is an asset. I've worked for foreign companies before and have fluent English skills.

I aim to become a well rounded software developer, who solves real world problems using the power of programming and technology. When it comes to learning I believe in getting my hands dirty with actual work instead of mugging up theoretical knowledge.

I am a dedicated Golang backend developer with 1.5 years of experience in designing and implementing RESTful APIs.
