Golang MongoDB Developers

Hello there, I am a Golang Developer

Experienced Full Stack Developer with a strong focus on backend development and software architecture, particularly using Java and Spring Boot. I bring solid experience designing scalable, maintainable systems and working across the stack with technologies like Golang, Vue.js, Node.js, Nuxt, C# and Python.

I am a golang developer (3+ years) actively looking for software engineering position. Before golang I worked with python (still using) and Java adding up to 9 years in software engineering. Developed mature software being used in a major university in Azerbaijan.

Lead/senior engineer who's built and transformed critical enterprise platforms across finance, logistics, and retail. I specialize in Go microservices, event-driven architectures, secure authentication systems. Led development of greenfield authentication platforms and custom security gateways. Passionate about observability, clean code, and continuously expanding system design knowledge.

I’m a backend engineer with 4.5 years of experience building scalable, reliable systems and developer tools. I’m passionate about solving real problems, improving workflows, and writing clean, maintainable code. I enjoy working independently and in teams that value growth and quality.

As a Software Engineer with substantial hands-on experience in designing and developing scalable, cloud-native solutions using Golang. My expertise spans a robust technology stack, including NATS for messaging, MongoDB for data storage, Kubernetes for container orchestration, and observability tools such as Prometheus and VictoriaMetrics. I have also worked extensively with CI/CD pipelines leveraging Argo CD and Tekton.

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

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
