I will build a backend in Go for your mobile or web app. REST API, PostgreSQL database, authentication, and deployment to your VDS or cloud.

What you get:
- Go HTTP API (Fiber or net/http)
- PostgreSQL with GORM
- JWT authentication
- Redis for cache and sessions
- Docker Compose for easy deploy
- Admin panel on request

I use this exact stack in my own products (a VPN service and a messenger), so it is proven in production. Clear code, documented endpoints, ready to deploy.
