I will build a secure golang backend api with jwt, oauth2 and clean architecture


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.

FAQ
Do you sign NDAs?
Yes.
Can you work on an existing codebase?
Yes. I can understand, debug and improve existing Golang applications.
What kind of projects can you build?
Anything backend! APIs, microservices, cloud deployments, real-time systems, automation scripts, and even AI or Telegram botsI turn your idea into a fast, scalable, production-ready solution.
Can you build SaaS backends?
Yes. Complete authentication, billing integrations, APIs, databases and deployment.
Can you add authentication to an existing Golang backend, or only build new ones?
Both. I can add JWT, OAuth2, SAML, or SSO to a backend you already have, or build the full system from scratch, your call.
What if I don't know exactly what auth setup I need?
That's fine, message me with what your app does and who your users are, and I'll recommend the right approach (simple JWT vs. full OAuth2/SSO vs. fine-grained permissions) before we start.
Can you deploy to AWS, Azure, or GCP?
Yes, Docker, Kubernetes, and deployment to any major cloud are included in the relevant packages.
