I will develop a scalable golang backend, microservices and rest API


About this gig
I build high-performance backends and APIs in Go engineered for scale, concurrency and reliability, not just to "work in a demo."
What I deliver: clean, idiomatic Go services; REST and gRPC APIs; database integration (PostgreSQL, MongoDB, Redis); authentication and middleware; structured logging and tests; and full source code. I also rescue and refactor existing Go codebases.
Stack: Go, PostgreSQL / MongoDB / Redis, gRPC & REST, Docker, Kafka/RabbitMQ where needed. 8+ years of backend engineering, 150+ projects delivered, 5.0.
Ideal for SaaS startups and teams that need a backend that holds up under real traffic.
Please message me before ordering so I can review your requirements and scope accurately.
Feel free to reach out to me with any API-related requirements you may have. I am more than happy to discuss your project needs without any charge. Simply drop me a message in the inbox before placing an order, and we can start our conversation.

- C/C++
- Java
- Golang
- Python (Flask/Django)
- Node.JS
Furthermore, I have experience working with various databases, including SQL, NoSQL, and clusters of databases such
