About this service

Summary

I provide scalable, high-performance backend API solutions using Python (FastAPI, Flask, Django) or Golang (Fiber, Echo, Gin). My solutions are fully containerized with Docker and, where applicable, include Docker Compose for orchestrating multi-container environments. This ensures seamless deployment, scalability, and maintainability across cloud platforms such as AWS, Azure, or on-premise infrastructure.

Each API is designed with security, efficiency, and reliability in mind, implementing best practices for authentication, logging, monitoring, and CI/CD automation. Whether the API is designed for internal microservices, a SaaS platform, or mobile/web applications, my service covers all aspects of backend API development.

Who is this Service For?

✅ Startups & SMEs – Looking for a fast, cost-effective API solution. ✅ Enterprises – Needing scalable and production-grade APIs. ✅ SaaS Developers – Building cloud-native API backends. ✅ Mobile & Web Developers – Requiring a secure and efficient API backend.

Final Thoughts
