My own product: 27 salary, benefits and tax calculators for Peru and Mexico, live in production. I designed it, built it and maintain it.
- 27 calculators
- 2 countries: Peru and Mexico
- 1,267 passing tests
Every result shows its step-by-step breakdown with official parameters, and the number on screen is pinned by an automated test: S/ 5,000 with ONP gives S/ 4,120.00, in the app and in the test.
