What I'm looking for

I want to keep building backend services in Go—clean REST APIs, reliable async processing, and maintainable architectures. I’m excited to work on scalable microservices and deliver production-ready features with solid testing and observability.

I’m a backend developer building Go microservices with layered architecture and clean interfaces. In my 6 months of backend work, I developed REST APIs with validation, consistent error handling, and DTOs.

I design robust async systems using queues, worker pools, and retries with exponential backoff, while also applying idempotent operations and structured JSON logging. I containerize services with Docker and manage configuration via environment variables.

On the project side, I built Emailback for email sending and queuing with deduplication, retries, and idempotency, plus batching with goroutines and worker pools. I also created Marketback, a marketplace backend with clean architecture (domain/usecase/repo), caching, RBAC, and REST API pagination—always aiming for maintainable, production-ready backend systems.
