About me

Software developer experienced in mobile app development (iOS: Swift, SwiftUI, Xcode) and in projects for the telecommunications industry.

I take on projects in: • mobile and web apps (iOS, React Native, PWA), • Python scripts and automation, REST API integrations, Google Cloud / BigQuery, • Excel and data workflow automation, • technical translations PL / EN / RU.

How I work: a clear quote, timeline and milestones before we start; regular progress updates along the way; clean, documented code (Git) at the end. I run a registered business in Poland and issue invoices.
