Where I've worked and what I did there.

A shopping app used by several supermarket chains. I work on checkout, payments, vouchers and the user account: I'm moving these screens to Jetpack Compose and Flow and adding unit and screenshot tests. Alongside that I build tools for the team on top of Claude Code: skills, sub-agents and MCP servers for searching code and documentation.

An Android app where the main topics were UI and accessibility. I built reusable UI components, added screenshot tests and shipped accessibility fixes after WCAG audits that I took part in myself.

A large Android shopping app: sign-in, product search, checkout. I led the move of code to Kotlin Multiplatform and the split of the monolith into modules. I introduced Compose, coroutines and writing tests before code to the team.

NordLocker for Android, an encrypted file storage in the cloud. I built product features, including file sharing. I moved the app from Kotlin Multiplatform Mobile to native code and split one large module into several smaller ones.

NHL and Disney+ on phones, tablets, Android TV and Fire TV. Among other things I worked on GroupWatch, the paywall and TV versions of screens. I improved the accessibility of the interface and proposed product changes where the platform did not allow what had been designed.

Fox Sports GO, a sports streaming app for phones and tablets. I developed user-facing features and the UI, network and database layers. Unit tests and clean architecture were standard here.

I started with an internship in the mobile apps department: I wrote a simple e-commerce app and a few things for the main Ceneo app. Then I stayed on as a junior and worked on the Android app.
