NAME

dominik — frontend engineer who architects apps from the first commit and keeps them predictable under real-time data.

SYNOPSIS

dominik --frontend --react --typescript [--lead] [--full-stack=learning] [--remote | --poznan]

DESCRIPTION

I architect frontends from the first commit, design state that stays predictable when real-time data hits it, and care about the details users feel but rarely notice. Web, mobile, admin panels — React all the way down. Now growing into backend and infrastructure, on the way to full-stack.
