DRIVEN BY CURIOSITY Tübingen, Germany
Hi, I’m Matze.
Turning ideas
into reality.
I build apps, explore artificial intelligence and create things that make everyday life better.
01 / SELECTED WORK
Built from curiosity.
From a first small tool to an AI app.
A glimpse of what I’m working on.
Personal weekly meal plans, matching shopping lists and upcoming meals at a glance. Also known as V&M Fuel.
A dedicated interface for agentic development: projects, chats and multiple coding agents in one place.

Speak instead of typing: native voice input for Windows and Android, with separate meeting recording and transcription.

Which findings can vision-language models identify without task-specific training? Comparing BioMedCLIP and MedCLIP with different prompting strategies on chest X-rays.
Private source
A team project reconstructing 3D scenes from multiple calibrated camera images. A neural model produces a 3D Gaussian representation that can be rendered from new viewpoints.

A search engine for websites about Tübingen: crawling, indexing and ranking in a collaborative university project.
Developing and training reinforcement learning agents to face other agents in a provided hockey environment. The project concluded with a competition between teams.

It starts with a sketch.From a first sketch to an AI-generated image. A drawing canvas meets prompts, visual styles and creative experiments.
Survive waves of pirates on an island, collect loot and upgrade your equipment. The goal: build a ship and escape.
Open RepCounter, Gem Calculator, Card Manager and Egg Timer from one shared interface.
Count repetitions, track workout time and stay focused on your set. One of my first web and Android projects.
02 / THE PERSON BEHIND THE CODE
More than
just code.
Matze / aka matooo
I’m curious about how things work. And how to make them a little better.
I study computer science in Tübingen. My projects bring together software development, artificial intelligence and practical ideas — from workout tools to personal everyday companions.
Away from the screen, calisthenics, fitness and nutrition are part of my everyday life. My background as a paramedic adds another perspective: technology matters when it helps people.

Try out ideas and learn by building projects.
Keep going
In training and when tackling the next challenge.
03 / MY TOOLKIT
What I bring.
Technologies I work with in my
personal and collaborative projects.
Web & Apps
From a browser-based idea to a mobile application.
AI & Data
Understand models, experiment and put them to work in projects.
Systems & Tools
The foundation behind working software.
Agentic Engineering
Designing and orchestrating autonomous development workflows and integrated apps with Codex, Grok Build, Claude Code (app and CLI) and Antigravity (app and CLI). Strong focus on context management, structured agent instructions, MCP, plugins and API-based AI integration.
04 / PROJECT DIRECTORY
The collection.
Apps, experiments and first steps.
Every project is part of the learning curve.
PROJECT / NAME18 projects
01MyLifeGraphApps & ToolsFlutter
02Pencil2PixelAI & ResearchPython
Draw in the browser, add a prompt and generate images through a Python backend. The project includes brushes, an eraser, undo/redo and adjustable generation parameters.
03NutriPilotApps & ToolsJavaScript
A nutrition project built around personal preferences, weekly planning and shopping lists. The original V&M Fuel project website remains available in the archive.
04Yapp AIPrivateAI & ResearchJava
A native application in development, featuring a microphone overlay, dictation history and configurable speech providers. Device validation is still part of ongoing development.

05Tübingen Search EngineAI & ResearchPython
Created in the Modern Search Engines course. A pipeline turns websites into a searchable index and presents results through a Streamlit interface.
06RepCounterApps & ToolsJavaScript
Count repetitions, track workout time and stay focused on your set. One of my first web and Android projects.
07Zero-Shot Chest X-RayPrivateAI & ResearchPython
A research project on zero-shot multi-label classification with BioMedCLIP and MedCLIP across CheXpert, NIH ChestX-ray14 and PadChest. We compared positive and negative prompts, LLM-generated descriptions and composed strategies. Evaluation shows that the benefit of a prompt strategy strongly depends on the model and dataset.

11AquaDefenderGamesC#
12Hockey RL AgentsPrivateAI & ResearchPython
My contribution to the team: a Soft Actor-Critic (SAC) agent, training against a pool of different opponents and benchmarks to compare models. The trained agent competed against other teams’ agents in the final competition.

133D Reconstruction with Gaussian SplattingPrivateAI & ResearchPython
For the project, we developed a pipeline that fuses image features from multiple cameras to predict a metric 3D representation of objects and their surroundings. The work covered model training, novel-view rendering and evaluation of reconstruction quality.
