PERSONAL PROJECT

MyAnalyze - from idea to release

  • UI: React / TypeScript
  • API: Node.js / Express
  • Data: SQLite
  • Windows: Electron
  • Tests: Jest / RTL
  • CI: GitHub Actions

I built MyAnalyze from idea to release, covering interface design, application logic, development, testing and documentation.

What you can review

  • Published version 4.0 with a Windows installer, mobile interface, and Polish and English UI.
  • CSV/PDF imports, transaction history, accounts, goals and forecasts in one product.
  • UI and API tests, regression testing with temporary SQLite databases, and automated builds and tests in CI.

I use AI for design, coding and diagnostics. I decide the scope of changes and verify how they work.

How I work with teams

  • I explain technical findings to users and developers, agree on next steps and combine independent investigation with teamwork.
  • I learn new tools through real tasks and choose them based on the problem, not the trend.
