About
Android has been my day job since 2016, most of it in Warsaw fintech. At my last full-time role I rebuilt the card-payments module of a banking app with 2M monthly users, cutting transaction drop-off by a third. These days I take on contract work: Kotlin rewrites of legacy Java codebases, modularisation, and getting flaky CI pipelines under control.
