ERP implementation specialist focused on system integrations — especially KSeF / FA(3) e-invoicing. When an integration needs more than a black-box check, I build tools that stay auditable: every finding ties back to an official source.
Public highlights
- ksef-fa3-checker — FA(3) / KSeF invoice validator with auditable MF source quotes (demo)
- sortlab — sorting algorithm measurement lab (Python): instrumentation, complexity fits, charts
- ios-obd2-ble-diagnostics — native iOS OBD-II over BLE (SwiftUI + CoreBluetooth)
- sfml2d — 2D graphics with SFML (C++)
- weather_api — simple Python weather API
