I will build a scalable golang backend rest API or microservice
Rajender J
About this gig
I will build or extend a clean, maintainable Golang backend for your web, mobile, SaaS, or internal product.
Depending on the selected package, your delivery can include REST or gRPC endpoints, PostgreSQL integration, authentication and authorization, background jobs, third-party API integrations, structured logging, health checks, tests, Docker, and concise API documentation.
My focus is production-minded software: explicit contracts, predictable errors, secure defaults, readable Go code, and a handoff your team can continue.
Typical work includes new API modules, backend feature development, database-backed services, microservices, integration layers, and reliable internal tools. Source code is included in every package. Database integration and detailed comments are included where stated.
Please send your data model, API contract, expected request and response examples, and deployment target before ordering. Large migrations, payment systems, regulated data, and real-time platforms require a custom offer.

FAQ
Which Go frameworks and libraries do you use?
I choose the smallest sensible option for the codebase, including the Go standard library or an established router and libraries when they add clear value.
Is deployment included with the API?
Docker and deployment preparation are included only where stated. A managed production rollout can be added after I review the hosting, secrets, database, and rollback process.
Can you fix or extend an existing Go backend?
Yes. I can add a defined feature or endpoint set to an existing service. For diagnosis, crashes, race conditions, or performance work, my dedicated Go debugging service is usually a clearer fit.
Can you include authentication and database integration?
Yes. Authentication, authorization, and database integration can be included in the Standard or Premium scope after the data model, roles, security requirements, and existing stack are reviewed.
What do you need before starting?
Please provide the product goal, endpoint list or API contract, data model, sample payloads, authentication needs, deployment target, and repository access when applicable. Never send secrets in chat.
