You will get Go backend REST API with PostgreSQL and JWT
Project details
I will develop a scalable and secure backend REST API using Go (Golang) for your web or mobile application.
This service is ideal for SaaS platforms, startups, internal tools, and high-performance systems that require clean architecture and reliable database integration.
What This Project Includes
✔ RESTful API development in Go
✔ Clean modular project structure
✔ PostgreSQL or mongoDB integration
✔ JWT authentication & role-based access
✔ Input validation & structured error handling
✔ Database schema design
✔ Environment configuration
✔ Docker setup (if required)
✔ API documentation
Technologies
• Go (Golang)
• Gin / Chi / Echo
• PostgreSQL /mongoDB / MySQL
• JWT Authentication
• Docker
• AWS-ready deployment
Suitable For
• SaaS backend development
• Mobile app APIs
• Admin dashboards
• Startup MVP backend
• Secure internal systems
Send a message with your backend requirements and I will help you structure the right API architecture.
