I will build a high performance rest or grpc backend API in go
Manas J
About this gig
Need a backend that's fast, clean, and built to scale?
I build production-grade backends in Go one of the fastest and most efficient languages for server-side systems. While most freelancers work exclusively in Python or Node, I bring Go expertise that delivers measurably lower latency and resource usage for the same workload.
I've built systems with gRPC communication layers, Redis caching, Prometheus observability, and full Docker Compose deployments from the ground up including Keiro, a self-hostable adaptive RAG infrastructure with a Go API gateway handling intelligent routing at its core.
What you get:
High-performance REST or gRPC API in Go
PostgreSQL integration with clean repository pattern
JWT authentication + middleware
Docker + Docker Compose deployment
Swagger/OpenAPI documentation
Source code + detailed comments
Go developers are rare on freelance platforms. You're getting one who builds production systems, not tutorials.
Message me before ordering scope varies and I want to make sure we're aligned.

FAQ
Why Go instead of Python or Node for my backend?
Go compiles to a single binary, uses minimal memory, and handles concurrency natively. For APIs serving real traffic, it outperforms Python/Node significantly without the complexity of Java or C++.
Can you build both REST and gRPC in the same project?
Yes. A common pattern is exposing a REST gateway externally while using gRPC for internal service communication. I've built exactly this architecture and can implement whichever combination your use case needs.
Can this backend connect to an AI or ML service?
Yes. I can wire the Go backend to a Python-based ML service via gRPC or REST — this is a pattern I use in my own projects. Ideal if you want Go handling the API layer and Python handling the AI logic.
Will the code follow production standards?
Yes — clean architecture, separation of concerns, environment-based config, proper error handling, and structured logging. Not tutorial-grade code.
What do you need from me to get started?
A description of what your API needs to do, your database preferences, and whether you need REST, gRPC, or both. I'll confirm scope before starting.
