About

I'm a junior full-stack developer with a passion for AI and real-time systems. I've built backend infrastructure, mobile apps, and cloud-native solutions, always aiming to solve real-world problems through technology. I enjoy working on impactful projects, and I've had the chance to prove myself in hackathons and team collaborations.

My Projects

Check out my latest work

I've worked on a variety of projects, from simple websites to complex full-stack applications. Here are a few of my favorites.

Voyagr

Voyagr

Hackaton project. Voyagr is a voice-controlled system that allows users to search for hotels and flights based on their preferences using natural conversation. Leveraging ElevenLabs' Conversational AI, the application interacts with users in real time, dynamically asking follow-up questions to refine the search experience. Voyagr has won 3rd place at the ElevenLabs Worldwide Hackathon in Warsaw and also received a global reward from lovable.

MoveIt

MoveIt

I have built whole backend infrastructure for this app - powered by GTFS feeds from cities. Also, I have implemented real-time tracking of public transport vehicles. Moveit is a public transport application that allows you to track the real departure time of public transport vehicles in cities such as Warsaw, Tricity, Kielce and Rzeszów.

Upldr.

Upldr.

This project is not active anymore. It was a simple media uploader that allowed you to upload files and get a link to them. It's main purpose was to allow the customization of the link preview display on platforms like Discord and Telegram. It was a simple project that I made to learn how to use the AWS S3 service and to dive deeper into API development.

Corion

Corion

Semi-active project. Corion is a multi purpose Discord bot that allows you to manage your server. It has a lot of features like moderation, music, own economy and more. It is a project that I made to learn how to use the Discord API and how to make a bot that can be used by other people. It was what really got me into programming!

Hackathons

I like building things

To this day, I have attended 2 hackathons. People come together and build incredible things. It was eye-opening to see the endless possibilities brought to life by a group of motivated and passionate individuals.

    🥉 We secured 3rd place at the ElevenLabs Worldwide Hackathon in Warsaw! I developed an innovative voice-controlled system that allows users to search for hotels and flights based on their preferences using natural conversation. Leveraging ElevenLabs' Conversational AI, the application interacts with users in real time, dynamically asking follow-up questions to refine the search experience. This project showcases the potential of voice interfaces in simplifying complex search workflows and improving accessibility.

    Techni Schools Code Camp

    Warsaw, Poland

    🥈 We secured 2nd place at the Techni Schools Code Camp in Warsaw! Together with my team, we built a project based on a predefined hackathon theme: mental support. We were also assigned the name cyk.pl. Our solution was an AI-powered psychologist based on the 'Bielik' model. It featured an initial diagnosis capability, AI-driven conversations, and the option for a human consultant to supervise the dialogue and step in when needed.
