Projects
A few things I’ve built at work, at a hackathon and at home.
City of Poznań · 2025–2026production
A chatbot that speaks the Poznań dialect
ProblemThe idea for a chatbot that speaks the Poznań dialect was ours. We pitched it to the city, they liked it and wanted our solution on their website.
What I builtAn agent that talks in the dialect. Plus an automatic check of whether an answer sounds like Poznań.
OutcomeSince October 2026 the bot is live on the City of Poznań website. In my master’s thesis I checked whether it actually handles the dialect better and how to assess that automatically.

Voice-controlled lights
ProblemI wanted the lights in my room to change on their own, blend into smooth gradients and follow my own themes, not just switch on and off.
What I builtControl by voice and through a chatbot, wired into my smart-home setup and hosted on a server at home.
OutcomeI switch the lights on and change the room’s theme by voice or through a chatbot.

HackYeah · September 2026final
eKsiążeczkaZdrowia
ProblemAfter waiting over a month for a specialist, I could no longer describe what hurt and when. I hadn’t written anything down when the symptoms appeared.
What I builtWith my team, an app for logging symptoms as they happen. The data stays on the phone, and the doctor gets it without any server in between.
OutcomeHackYeah final. We later used the idea for the app’s demo at my company for two products.
TypeScript · React · Vite (PWA) · IndexedDB (Dexie) · WebCrypto · Node.js · WebSocket · Tesseract.js
independent photographer · 2026architecture to deployment
Photo shoot generator
ProblemA photographer needed a site where clients could order, pay for and receive a generated photo shoot on their own.
What I builtThe architecture, frontend, backend, database, image generation and Przelewy24 payments, all the way to production.
OutcomeRealistic photo shoots. Templates can be extended with new ones, and the client configures everything on their own.

DomData · 2025–2026production
Bank forms from a description
ProblemBuilding bank forms in the Ferryt low‑code platform means tedious manual UI configuration.
What I builtAn agent that turns a plain-language description into working Ferryt components. It runs on a local Qwen model so the bank’s data never leaves the company.
OutcomeYou describe a form in plain text and get ready-made components in Ferryt.
Python · Qwen (local LLM) · Prompt engineering · Ferryt API
OLX · 2024–2025
Ad banners without a designer
ProblemSmall businesses want to advertise but have no designer to make them a banner.
What I builtThe backend of a GenAI system combining LLMs with image generation models, with a FastAPI and Redis pipeline handling many requests at once.
OutcomeI based my engineering thesis on this project.
Python · FastAPI · OpenAI · Redis · Pydantic
