About this gig

Build Fast, Scalable & Secure Golang Backends (Auth Built In)

Most Golang gigs build you an API and stop. I build the API and the authentication layer that protects it so you're not hiring someone else later to secure what I shipped.


7+ years building production Golang systems: REST APIs, gRPC, microservices, plus the JWT, OAuth2, SAML, and OIDC auth that sits in front of them. Built for fintech, AI, IoT, and enterprise SaaS including real access control (IAM, SSO, permissions), not a login form bolted on.


What I build:

  • Golang REST APIs & gRPC services
  • Microservices architecture
  • Auth & authorization (JWT, OAuth2, SAML, OIDC, SSO)
  • PostgreSQL, MongoDB & Redis
  • Docker & Kubernetes
  • AWS, Azure & GCP deployment
  • Performance optimization & refactoring


Why work with me:

  • I design the permission model first, so the API isn't rebuilt later for real access control
  • Production-ready, documented code
  • Clean architecture that survives scaling past MVP
  • Fast communication, deployment support included


Message me before ordering with what you're building I'll tell you honestly if Golang fits and which package matches your scope.
