About this gig

Need a fast, reliable backend? I build REST APIs, microservices and backend services in Go (Golang) - clean, well-tested code that scales under load.

WHAT I BUILD

  • REST APIs and JSON endpoints in Go
  • Microservices and backend services
  • Database integration (PostgreSQL, MySQL, Redis)
  • Authentication, JWT and middleware
  • Dockerized and ready to deploy

WHY GO

Go is built for backends: fast, concurrent and memory-efficient. Your service handles more traffic on less hardware, with code that stays simple to maintain.

HOW IT WORKS

First you tell me what the API needs to do. Then I design it, build it, test it, and hand it over with clear docs. The source code is always yours.

Not sure about scope? Message me with your idea and I'll tell you honestly what it takes. Let's build a backend you can rely on.

I'm Jose, a full-stack developer from Lima, Peru. I build backend systems in Go for a nationwide platform, and run several of my own SaaS products live in production on my own server. I build fast, SEO-ready landing pages and small web systems - real products with databases, auth and deployment, not just templates. Shipped: a multi-tenant veterinary SaaS with e-invoicing, a 24/7 distributed bot platform, an AI-powered clinical documentation tool, and bilingual SEO-first sites. I use AI tools daily, so I move fast without cutting corners. Let's talk about your project.
