I will fix golang backend, rest api, grpc and microservice issues
Moyosoreoluwa
About this gig
I will debug, fix, and optimize Golang backend systems including REST APIs, gRPC services, and microservices architectures.
I help resolve production issues such as broken endpoints, database errors, performance bottlenecks, memory leaks, and service failures.
I specialize in building and maintaining scalable backend systems using Golang with clean architecture and best practices. I work with
- PostgreSQL
- MongoDB Redis
- Docker, and cloud environments
to ensure your system is stable, fast, and production-ready.
My services include
- bug investigation
- API debugging
- backend optimization
- microservices troubleshooting
and performance improvements. I also refactor code to improve structure, reliability, and long-term maintainability.
If your Golang backend is slow, unstable, or breaking under load, I will analyze the root cause and deliver a clean, efficient, and scalable solution.

FAQ
What types of Golang backend issues can you fix?
I fix issues in Golang REST APIs, gRPC services, microservices, and backend systems. This includes broken endpoints, database errors, authentication issues, performance bottlenecks, concurrency bugs, and deployment-related problems.
Can you work on existing or incomplete backend projects?
Yes. I can debug, analyze, and improve existing Golang codebases whether partially built, broken, or production systems. I also help refactor and stabilize poorly structured backend systems.
Do you optimize API performance and scalability?
Yes. I optimize backend performance by improving database queries, reducing latency, fixing memory leaks, and enhancing concurrency handling in Golang applications.
Which technologies do you work with?
I work with Golang (Gin, Fiber, Echo), REST APIs, gRPC, microservices, PostgreSQL, MongoDB, Redis, Docker, and cloud platforms like AWS and GCP.
Will you explain the fixes you make?
Yes. I provide clear explanations, bug reports, and optional documentation so you understand what was wrong and how it was fixed for future maintenance.
Do you offer long-term support after fixing issues?
Yes. I provide post-delivery support depending on the package to ensure your backend remains stable and production-ready after fixes.
