About me

Hello there! I am a full-stack software developer and student from Brno, Czech Republic. I'm currently pursuing my Master's degree in Information Technology and Artificial Intelligence at the Brno University of Technology

I have been programming as a hobby since childhood and professionally for over six years. I mainly work with mobile and web technologies, but I consider myself a generalist. I have a strong passion for learning and I can adapt very quickly to new technologies.

Aside from programming, I also enjoy playing video games, coffee and food (of course). I also love to travel, hike, and mountain bike.

Decentree Software

Decentree is a blockchain and app development company, which I co-founded. I am currently working on growing the company and developing new products.

For traditional app development, we use React on the web and React Native on mobile. For blockchain projects, we mainly work with EVM chains (like Ethereum, Polygon or BSC) and Solidity.

Telidoo

Telidoo is a mobile app providing telecommunication services. The main feature is phone calls, which are cheaper than most mobile carriers and work even without an internet connection. The app also provides messaging, payments and other services for businesses.

I was involved from the beginning of the project, working on the native Android app and backend. The app was one of the first 3rd party dialer apps. Right now I'm in charge of the development team as the company grows.

Luftio Systems

Luftio is a smart IoT air quality sensor, that measures CO2, TVOC and other parameters. You can use it to monitor your home or office air quality in the mobile app or web dashboard.

I was in charge of firmware, hardware and backend development. The device is based on a custom PCB with a ESP32 microcontroller, which uploads the measured data in real-time via MQTT.

Sati App

Sati is a mobile app for helping with mental health. It connects people with volunteers they can talk to about their problems.

I maintained the app after the original developer, fixing bugs and adding new features. I migrated the voice provider to Twilio Voice SDK and created a custom solution to handle possible network issues.

IZOtrade

IZOtrade is a construction company for which I developed a custom internal mobile application.

The application is used for managing warehouse inventory, machine rentals and employee attendance. It's built using React Native and integrates with Google Sheets and the QR code reader.

UNIS

UNIS is a corporation providing industrial solutions.

I worked as an intern developing a React Native mobile app for a range of IoT tracker devices. Afterward, I developed C#.NET components for interfacing with Barcode/RFID readers. I also started development of a Xamarin mobile app to replace a legacy Windows CE PDA solution. Another project was introducing Docker containers with CI on Azure Devops.

Taskgoo is a personal project, a Google Tasks client for MacOS.

I developed the app using Swift and Xcode as a part of my high school finals. It's a simple task manager connected to the Google Tasks API.

It's open source on GitHub.
