A personal companion for planning, habits and focus. Daily check-ins meet a clear view of everyday life.
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.
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.

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
Selecting, exploring and integrating open-source LLMs and speech-to-text models into applications.
Backend & 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.
Linux, Servers & Networks
Setting up Linux servers, managing virtual machines and connecting services. Practical experience with Debian, Ubuntu and Proxmox, alongside foundations in subnets, firewall rules and VPNs.
04 / PROJECT DIRECTORY
The collection.
Apps, experiments and first steps.
Every project is part of the learning curve.
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
Project in focus
- Challenge
- Explore how vision-language models identify multiple findings in chest X-rays without task-specific training.
- Research project
- We compared BioMedCLIP and MedCLIP and different prompting strategies across multiple datasets.
- Technical approach
- Positive and negative prompts, LLM-generated descriptions and composed strategies are evaluated through image-text similarity.
- Finding
- The benefit of a prompting strategy strongly depends on the model and dataset. This is a research comparison, not a clinical product.
08Codex UIPrivateWebTypeScript
A personal web app for orchestrating coding agents, managing projects and chats, and voice input. The visual preview is an illustrative demo with sample content.
09Card ManagerApps & ToolsJavaScript
10Gem CalculatorApps & ToolsJavaScript
Compare magic items: which purchase saves the most time per gem spent?
11AquaDefenderGamesC#
12Hockey RL AgentsPrivateAI & ResearchPython
Project in focus
- Challenge
- Train an agent for an existing hockey environment to compete against other teams.
- My contribution to the team
- Soft Actor-Critic, training against a pool of opponents and benchmarks to compare models.
- Technical approach
- The agent learns its strategy through reinforcement learning; different training opponents allow comparisons under different conditions.
- Outcome
- The trained agent participated in the final competition against agents from other teams.
133D Reconstruction with Gaussian SplattingPrivateAI & ResearchPython
Project in focus
- Challenge
- Reconstruct a 3D scene from multiple calibrated camera images and render new viewpoints.
- Team project
- We developed a pipeline that combines features from multiple cameras to predict a 3D representation.
- Technical approach
- A neural model produces a representation using 3D Gaussian Splatting. Model training and rendering are part of the same pipeline.
- Outcome
- Reconstructed scenes can be rendered from new viewpoints. Reconstruction quality was evaluated in the project.
