I will develop high performance backend microservices in go golang


About this gig
Is your Node.js or Python backend struggling to handle high traffic?
You need Go (Golang). It is the language of cloud-native infrastructure, designed by Google for speed, concurrency, and scalability.
I am a Backend Engineer specializing in building high-performance microservices. I replace slow, monolithic legacy code with blazing-fast Go APIs that consume less memory and handle thousands of concurrent requests.
What I Build:
- REST & gRPC APIs: Using fiber, gin, or standard lib for maximum throughput.
- Microservices Architecture: Decoupled services communicating via RabbitMQ/Kafka.
- Database Optimization: Efficient queries with PostgreSQL, MongoDB, and Redis caching.
- Concurrency: Goroutines and Channels to handle heavy background tasks without blocking.
My Tech Stack:
- Languages: Go (Golang)
- Frameworks: Gin, Fiber, Echo, Gorm, Sqlc
- Protocols: REST, gRPC, Protobuf, GraphQL
- Tools: Docker, Kubernetes, AWS, Swagger/OpenAPI
Why Choose Me?
- Clean Architecture: I follow industry standards (Hexagonal/Onion architecture) so your code is maintainable.
- Performance First: I write code that is memory-safe and CPU efficient.
- Test Driven: I include unit tests to ensure stability.

FAQ
What will you need to start the work?
For bug fixes, I will need access to your website and a detailed description of the issue. For developing web pages or full websites, I will require all the content, specifications and any design preferences you have.
What if I need more than 5 pages for my website?
I am more than willing to develop more than 5 pages. However, we'll need to discuss the additional cost based on the complexity and the number of additional pages you require.
Do you use frameworks?
Yes, I typically use Gin or Fiber for REST APIs, but I can also use the standard library if you prefer zero dependencies.
Do you support gRPC?
Absolutely. For internal microservices communication, I recommend gRPC with Protobuf for low latency.
