What I'm looking for

I’m looking for a backend role where I can build scalable Go microservices and secure REST/gRPC APIs, work with distributed systems and messaging, and keep improving through clean architecture, system design, and continuous learning.

I’m a Backend Golang Developer with nearly 2 years of commercial experience building scalable microservices and high-performance backend applications. I focus on reliable backend architectures, performance optimization, and clean code practices.

At Nord Clan, I designed and maintained scalable Go microservices using Gin and gRPC, building secure REST and gRPC APIs with OAuth2/JWT authentication. I integrated PostgreSQL, Redis, MongoDB, MySQL, and Elasticsearch, and implemented asynchronous messaging with RabbitMQ, NATS, and AWS SQS.

I also brought observability and debugging into my workflow with Prometheus, Grafana, OpenTelemetry, and Jaeger, and improved performance through profiling and optimization. I enjoy Agile collaboration through architecture discussions, code reviews, and sprint planning, and I’m passionate about continuous learning in system design.
