Work

Things I've designed and built over the years. Newest first.

• NotchPrompter

  2025

  A teleprompter for macOS that keeps your eyes on the camera.

  Adjustable text size, scrolling speed and themes. Sits above whatever you are doing, so it works with any video conferencing or streaming app.

• RenderForm

  2023

  No-code automation for generating images, videos and PDFs from templates.

  A web-based graphics editor with an API behind it. Design a template once, then generate social media posts, banners, certificates or reports on demand.

• SimpleLocalize

  2021

  Translation management for software teams, synced with the codebase.

  Hosted translations reach 100M+ unique users every month.

  Includes translation hosting and a batteries-included CLI that automates the whole sync, so translations ship with the code instead of trailing behind it.

• VendingMetrics

  2018

  Real-time sales, inventory and machine monitoring for vending machine operators.

  Used to run 2,000+ vending machines worldwide, including Shell, Orlen and EkoOkna in Poland, plus universities and hospitals.

  Web and mobile apps on top of IoT integrations: custom ESP32 telemetry boards, card-reader integrations and third-party feeds such as Nayax.

• PlaceFlare

  2017 closed

  A map of places worth visiting near you, built around weekend trips across Lower Silesia.

  Made with my girlfriend, now my wife, after we realised we knew almost nothing about the region we had moved to. It found an audience through Wykop and Instagram, had a mobile app alongside the website, and ran with steady traffic until other commitments took over. The site is gone, but the trip blog we kept is here.

• Chess

  2013

  A chess engine written in C++, with full rules and a minimax opponent.

• PaxCosmica

  2012

  A real-time space strategy game for mobile, with space battles, resource management and a deep tech tree.

  Never finished, but some day it will be. The vision is something like Aegis Wing for phones, with multiplayer. Built with Java and LibGDX.

• True or False

  2011 discontinued

  An Android trivia game with multiplayer for up to four players over Google Play Services.

  5,000,000+ downloads and over 20,000 reviews. The #1 Android game on Google Play in Poland for six months in 2012.

  I eventually ran out of time to support it, and it is no longer on the Play Store.

There is plenty more on my GitHub: apps, libraries and all sorts of smaller tools.
