Three years of building and rebuilding mobile apps and websites, from the first sketch to the App Store. Some were handed to me. Some I started from nothing.

Design

UI, UX, prototypes, graphic assets, marketing materials and often the copy too.

Build

React Native and React, and native modules when the job needs one.

Think

I did not design these backends, but I shape how features should work and what the API should send. For simple projects I build a small backend myself.

Ship

Manual testing, analytics, push notifications, then App Store Connect and Google Play Console through to release.

01eXent

Built from zero

eXent

A mobile app for conferences and corporate events. I designed it, built it, led how it was made, and shipped it to both stores.

02Jedziemy Razem

From basic settings to a real product

Jedziemy Razem

A Polish carpooling app. When I joined it had only basic settings. Three years later it has AI route creation, badges, ride logging and invitations.

03OEE Tools

Rebuilt module by module

OEE Tools

Real-time production monitoring for factory floors. Almost nothing in the app is left from the version I inherited, and I built the marketing website from scratch.

04Action Audit

Action Audit, massively redesigned

The public face of a web and mobile auditing platform. It was already live when I joined, and I reworked it heavily over three years.
