About this gig

Need a reliable backend developer to turn your idea into a fast, secure, and scalable application? You're in the right place.


I build professional backend solutions using Node.js, Express.js, Java, Python, and FastAPI, with clean code and a strong focus on performance, security, and maintainability.


My services include:

  • Custom REST API development
  • Node.js and Express.js backend development
  • Python and FastAPI development
  • Java backend development
  • Database integration with MongoDB, PostgreSQL, and MySQL
  • User authentication and authorization
  • Third-party API and payment integration
  • Backend integration for React and React Native apps
  • API documentation and deployment support


Whether you need a simple API, a complete backend system, or a mobile app connected to a secure server, I can build a solution around your specific requirements.


I focus on understanding your project before writing code, keeping communication clear throughout the process, and delivering a reliable backend that is easy to maintain and expand.


Have a project in mind? Send me your requirements before placing an order, and lets build it properly from the start.
