Project details
Need a backend that is secure, scalable, and ready for production?
I build backend systems for SaaS products, mobile applications, startups, and internal business platforms using Go, Python (FastAPI), and TypeScript (Node.js).
What you'll receive:
✓ Secure authentication and user management
✓ Database design and integration
✓ Well-documented APIs
✓ Dockerized deployment
✓ Automated testing
✓ Logging, monitoring, and health checks
✓ Full source code ownership
✓ Deployment documentation
With 10+ years of software engineering experience, I've helped build systems that process real-time data, support business-critical operations, and run in production environments.
Whether you're launching a new product or improving an existing platform, I focus on delivering maintainable backend systems designed to grow with your business.
Every project is built around your requirements and not generated from a generic template.
