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.
