Projects

A collection of things I’m building, exploring, and bringing to life — from fashion and digital tools to creative experiments. Some are live, some in progress, others just getting started. All of them reflect what matters to me.

Werkpaar, a platform that connects people who want something made well with makers in Germany

Werkpaar

In ProgressStarted 2026

Platform | Made in Germany

Large supplier directories exist, and still a small brand or a research team has a hard time finding a German business that will make 50 or 500 pieces of something really well. Werkpaar wants to do that matching by hand: a short brief, two or three checked makers who like small runs, a paid sample before the order. Manufactories, craft businesses, workshops and labs on one side, people with an idea on the other. Right now I am gathering interest on both sides.

Ideenmelder, a red box like a fire alarm call point that holds a waterproof notepad and a pencil on the shower wall

Ideenmelder

In ProgressStarted 2026

Product | Gift

The best ideas tend to arrive in the shower and are gone by the time you are dry. The Ideenmelder is a small red box built like a fire alarm call point, with a pad of waterproof stone paper and a pencil inside. Lift the lid, write it down with wet hands, tear off the sheet. Right now I am only gathering interest: it gets made once enough people want one.

Wholefelt, a one minute ritual for your energy, morning and evening, without a ring or a watch

Wholefelt

In ProgressStarted 2026

Wellbeing | Daily Ritual

A one minute ritual for your energy, twice a day, without a ring or a watch. You pause, feel into your body, mind and heart, and name your energy in a few taps or on paper. After seven days it starts to show you your own rhythm: mornings against evenings, and what gives you energy and what takes it. Open test: no account, your rituals stay on your own phone.

Weitergang, a free guide that shows people who lost an industry job which meaningful jobs need them now

Weitergang

In ProgressStarted 2026

Career Change | Local AI

Thousands of people are leaving jobs in German industry right now, engineers and managers among them. Weitergang shows them which jobs with meaning need them: care, vocational schools, the trades and social organisations. Four questions in the browser, then three paths with how long they take, who pays for them and what they earn, every number with a source. A local AI project running on my own computers in Munich, free for the people who switch, no account, no tracking.

Step In, a learning app with challenges between friends that shows men how to step in against harassment

Step In

LiveStarted 2026

Learning App | Prevention

A small learning app against sexual harassment and violence towards women, and towards men too. Made for the men who would never hurt anyone but often stay silent. Five minutes a day of real scenes, from the train at night to the group chat, each with a hand drawn sketch, and the safe ways to step in. Friends challenge each other by link. No account, no tracking, in German and English. The first part of Beside; the questions are a draft until a specialist service has reviewed them.

Couchplatz, a free chat that points people in Germany to therapists and clinics that fit what they need

Couchplatz

In ProgressStarted 2026

AI Matching | Mental Health

Finding a therapy spot in Germany means months of phone calls, voicemails and waiting lists, and many people give up at the exact moment they were ready. Couchplatz lets you say what you need in plain words, your city, your insurance, what is on your mind, and points you to therapists and clinics from its directory that fit. An AI on my own computer in Munich only reads what you write; the replies are checked texts, so it cannot invent a practice or give medical advice, and nothing is saved. Practices add themselves in two minutes, and people can sponsor sessions for someone who cannot pay, straight to the practice. No account, no tracking, not a medical service.

Feedfilter, a browser extension that covers the Instagram posts you would rather not see, checked on your own computer

Feedfilter

In ProgressStarted 2026

Browser Extension | Attention

A browser extension that covers the Instagram posts you would rather not see. You name what to hide, for now alcohol or swimwear, and those posts arrive behind a soft grey panel you can tap to show. Every photo is read by a small vision model inside your own browser, the captions and hashtags too, so nothing about your feed is ever sent anywhere. Built for the quiet reasons a feed never asks about, a month without drinking, a harder week with the body. Two categories work today; typing your own words, and an iPhone version, come next.

raw. — a social platform where the friction is the feature. No AI, no paste, 300 characters.

raw.

On HoldStarted 2026

Social Platform | Anti-Social Media

A social platform built around a single constraint: you have to mean it. There is no AI writing, no paste, no drag and drop. The composer opens, you type, you post. Up to 300 characters, an optional photo chosen in the moment, and that is everything. No likes, no follower counts, no algorithmic sorting. The friction is the feature — what gets through is what someone actually sat down and wrote.

Ethicora, a private invitation based network for ethical fashion with mediated introductions and project collaboration

Ethicora

In ProgressStarted 2024

Platform | Ethical Fashion Network

A private, invitation based network for ethical fashion. Brands, makers, suppliers, advisors and investors are reviewed by a person before joining, profiles are structured for clarity rather than self promotion, and introductions are mediated instead of cold. Members post projects, for example a production partner for linen shirts in Italy, partners answer with proposals that show pricing, timeline and capacity, and the chosen team then works in one shared space where every phase, task and update is visible, from the first brief to the final product and later the campaign. No products sold, no money handled, no visibility rewarded.

Fair GPT, a chat model whose corpus is contributed and owned by its members

Fair GPT

In ProgressStarted 2026

AI | Data Cooperative

The large models were built on work that was taken. This is the opposite arrangement. Members contribute their own original writing to a shared corpus and hold a share of it. Contributions live in retrieval rather than in model weights, so withdrawing your work removes it from every future answer, every answer names the contributions it drew on, and your share is measured by how often your work is actually used. Invite only, and running entirely on local hardware.

LiveStarted 2026

Web Tool | Money & Subscriptions

A subscription tracker for people who forget to cancel.

PAX PAELLA, paella to take away and sweet paella in Munich

PAX PAELLA

In ProgressStarted 2026

Gastronomy | Munich

Paella you take with you. Precooked in one large pan, served in minutes, eaten in a lunch break, in four pans from vegan to squid ink black rice. From two in the afternoon the same pan turns sweet: rice pudding with toppings you pick yourself. The shop stays deliberately tiny, a kitchen and seats for two to eight people in Schwabing or around Gaertnerplatz. The idea started in a garage in Sevilla where one man cooked a single pan every day until it was empty. Opening planned for spring 2027.

Briefs, contracts, past projects, all queried privately, with nothing sent to any cloud. Built for creative studios and agencies that handle confidential client work under NDA, where putting anything into a US cloud tool is simply not allowed. The promise in five words: what you build is yours. An independent project: a one time purchase at 99 EUR, instant download, runs fully offline on your own machine.

Worth by MAR, a fair pricing companion for makers who undercharge

Worth

LiveStarted 2026

Web Tool | Pricing & Small Brands

A calm pricing companion for people who make things by hand and quietly charge too little. Tell it the honest costs behind one piece and it returns three grounded numbers: a floor you must never sell below, a fair price that pays you a real wage, and a signature price that asks for the full worth of the work, each with its reasoning shown. Free to use, and everything stays in your browser. An optional Full plan adds the never discount playbook, five word for word scripts for the hard moments, a staged plan to raise your prices without losing your audience, and a PDF to keep.

The Disconnect, an anonymous space for short honest moments where nothing can be pasted or generated

The Disconnect

LiveStarted 2025

Web Tool | Mental Health & Wellbeing

A quiet corner of the internet for one honest thought at a time. There are no accounts, no followers and no counters, only single moments that arrive one after another, and all you can do is say that one relates to you or keep it for later. Pasting is switched off and the typing rhythm itself is checked, so every word has to be written by a person instead of dropped in from a model.

Headroom

LiveStarted 2026

Web Tool | Focus & Neurodivergent Minds

A calm triage tool for a mind that runs on a thousand ideas and finishes few of them.

Free to use. An optional Full plan turns the board into weekly milestone ladders, four short guides for a fast mind, a printable Sunday ritual, and a PDF you can keep. Built from a personal method for living and working with a fast, nonlinear brain.

LiveStarted 2026

Web Tool | AI & Prompting

A guided builder that turns a rough idea into a strong, reusable prompt for any model.

An optional Full workshop saves a whole prompt library on your device, adds variables so a prompt becomes a reusable template, includes starter recipes, and exports to PDF. The natural next step from here is the Local AI Founder’s Toolkit.

Unseen Bond, a bracelet concept for the bonds you cannot see, with a gold and silver intertwined heart mark

Unseen Bond

ConceptStarted 2020

Fine Jewellery | Concept & Brand Identity

A jewellery concept from 2020: a bracelet for the bonds you cannot see, the people still here and the ones we only feel. At its centre an infinity loop knots into a heart and becomes the clasp, in black metal or silver with a magnetic close and an engraving hidden against the skin. It came with a full brand identity, a wordmark, a monogram and packaging, and is kept here as an archived piece of the work.

Connecting people in the real world. Creating a community of people who share the idea of meeting new people offline. Wearing the bracelet would identify a person as part of this group and signalise everyone else, social contact is welcomed.
