🧾 About

I work as an ERP implementation consultant, focused on system integrations — especially KSeF / FA(3) structured 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.

Structured e-invoicing: FA(3) / KSeF schemas, validation, error diagnosis
ERP integrations: document exchange, master-data mapping, interface contracts
Auditable validation: each rule cites its source, each finding explains how to fix it
Requirement analysis → implementation → acceptance, with the paper trail intact
Side projects where I get to measure things properly (algorithms, embedded, graphics)

🛠 Stack

Languages: Python, SQL, C++, Swift, Kotlin
