Experience & Projects

A selection of my recent work and key contributions

Gym app MVP
  • .NET
  • Entity Framework
  • PostgreSQL
  • React
  • Zustand

I developed a software product aimed at gym management, currently deployed in 3 facilities as an MVP (Minimum Viable Product). The solution supports user management, attendance tracking, subscriptions, pricing, product inventory, and transactions.

The system was built with a .NET Web API backend and a local frontend using React. The architecture is API-centric, designed to act as the gym’s "brain." One example of this approach is the integration with IT systems to generate parking tickets via QR codes.

  • 70% improvement in administrative efficiency.
  • Clean separation of concerns between backend and frontend.
