About this gig

I will develop fast, scalable, and secure backend applications using Golang. Whether you need a REST API, GraphQL service, authentication system, or a complete backend solution, I can help build reliable and maintainable software tailored to your requirements.


My services include REST API development, GraphQL queries and mutations, database integration with MySQL or PostgreSQL, JWT authentication, authorization, input validation, error handling, unit testing, and backend business logic implementation. I follow clean architecture principles and Go best practices to deliver high-quality, production-ready code that is easy to maintain and extend.


I can also assist with database design, query optimization, API documentation, middleware implementation, logging, and performance improvements for existing applications.
