I build ML systems, developer tools,
and things you can play with.

Two line items. One total to check.
One rule from the real validator. Synthetic input; no model call.
I built a document-extraction harness that checks model output, with a benchmark you can replay offline.
View repositoryInteractive flow diagrams, interface components, and SVG motion. Copy a working example, change its configuration, and make it your own.
FlowKit connects sources to selectable outcomes. Alongside it: a component gallery, motion controls, and a JSON playground. Built with plain HTML, CSS, and JavaScript.
A feed planner for arranging photos, comparing layouts, and keeping a visual posting plan in your browser.
Drag images to insert or swap them. Save a layout, or export and restore a backup. The planner does not post to Instagram.
More room for tables, code, and long answers. An adjustable chat width for Claude, with keyboard shortcuts and saved preferences.
A small Tampermonkey userscript changes the chat column width. Reset removes the override and restores the site's own layout.
Independent utility for claude.ai; not affiliated with Anthropic. Live-site compatibility has not been verified for this portfolio.
Keyboard and controller controls for Tinder's web interface. Navigate photos, remap shortcuts, and adjust the card layout from a compact control deck.
A userscript with a live HUD, focus mode, and adjustable card sizing. Decision inputs use a cooldown and checks for blocking overlays.
Unofficial; not affiliated with Tinder or Match Group. Live-site compatibility has not been verified for this portfolio.
A German-language tool for classifying calls and exploring the resulting reports. Guided walkthroughs explain the real controls, from evaluation to CSV export.
Pause a tour and take over, correct an evaluation, or filter the manager report. The portable demo uses synthetic data and resets on reload.
Independent prototype. Company authentication, telephony, and real service orders are not connected.
An embeddable gallery and inspector for 3D models. Search a collection, filter by category, and open an asset to explore it in 3D.
Add a custom element and provide your own models and posters. The interface stays inside Shadow DOM; the renderer loads when needed.
At Ergon, I automated model tuning for banking fraud detection, cutting experimentation time by 60%. I also worked on Android inventory apps and backend services. At ZHAW, I researched cloud systems and robotics.
I like building a small tool to understand a problem. I ask for independent reviews, and keep notes so the next person can pick up the work.
Outside work, I'm a volunteer firefighter in Winterthur.
