What I'm looking for

I am seeking backend roles where I can build scalable, secure microservices with Golang, work with modern databases and messaging systems, and contribute to well-tested, maintainable platforms in collaborative teams.

I am a Backend Engineer with 4+ years of experience building scalable, secure backend systems primarily using Golang. I focus on REST APIs, gRPC, microservices, Clean Architecture and DDD, and have delivered production-ready services that emphasize performance, security, and testability.

My work spans MongoDB, PostgreSQL, MySQL, RabbitMQ for async processing, FCM for real-time notifications, and containerized deployments with Docker. I have documented APIs with Swagger, integrated API gateways like Kong, and consistently improved maintainability through clear layering, testing, and secure JWT-based authentication.
