About Me

Hey there 👋, I am Marc, a passionate developer and musician from Berlin. While not tinkering with one of my many side projects, you can find me singing, playing the piano, or learning to play the trumpet.

I'm regularly writing about topics I find interesting. You can find them on the main page of this site.

Projects

An incomplete list of projects I've worked on in the last few years. You can find their source code on my GitHub.

Projects with an asterisk (*) are personal favorites.

ZuBerlin and ZuGarden* (2024-)

ZuBerlin and ZuGarden are week-long immersive residencies to connect groups of 80-120 peers working, collaborating, and learning together at the bleeding edge of technology in fascinating, co-creative spaces all around the world. It's inspired and created by participants of Vitalik's Zuzalu and ZuConnect.

ephema* (2023-)

We are a web3 research group focused on unraveling truth at the cutting edge of the Ethereum ecosystem, receiving grants from Ethereum Foundation, Uniswap and Arbitrum. Some of my work includes BlobFusion and the Blob Creator, both tackling problems related to EIP-4844. We are also the team behind ZuGarden/ZuBerlin.

ReviewLayer (2023-)

ReviewLayer is my answer to the question "Isn't there a better way?" to the feedback process between developers and designers. No need anymore for sending lots of Slack messages with annotated screenshots.

Mental Garden* (2022-)

With Mental Garden, I'm offering free guided monthly reflections and a free Yearly Reflection. My aim is to help people build a regular habit of introspection and live a better, more deliberate life. This is my regular writing outlet where I process the topics currently on my mind.

Audiate* (2022)

A research tool I created to annotate audio files with measures/bars. The annotations can then be used to play back audio and (handwritten) sheet music simultaneously. To reduce the amount of manual work, a lot of effort went into creating a super smooth UX. The annotations can be exported into various formats like JSON and MEI.

Click The Number* (2016, 2022)

Click on the numbers from 1 to 25 in ascending order as fast as you can. A friend of mine completed the game in less than 11 seconds. How fast are you? 🤔

It's a fun little reaction game that I return to every now and then.

Wer Besiegt Paul Live* (2014-2023)

Since 2014, I come together every year with a few friends to organize Wer besiegt Paul?, Germany's largest gameshow produced entirely by volunteers. We transform a sports hall into a big TV studio and welcome over 800 guests – fully non profit. During the show, one candidate competes against Paul in 15 games for a jackpot of more than €4000.

One important part of the show is the motto "participate instead of just consuming" ("mittendrin statt nur dabei"). The audience gets the opportunity to become part of the show through an online app and influence the course of the event.

With this app I designed and developed, everyone in the audience can become part of the show – even when they are not directly on the stage. This is the biggest web development project I've created entirely on my own.

Prakti (2019)

As part of an internship in a public school, I wanted to research how much time teachers leave their students to answer a question. Prakti, a progressive web app (PWA) based on React and Material UI, solved a very real pain point for me: collecting that data in the class room. I published an analysis of the data I collected over the course of six weeks.

Stellar Wind (2018)

My first web3 project and an exploration of generative audio. An art-project that visualizes transactions from the Stellar Lumen network as small asteroids and interprets them as music. The higher the transaction value, the higher the pitch of the note.

My Music (2016-now)

Recently, I finished studying music and computer science. During that time, I started the band Freizeichen. We play "pop music with sharp 11", meaning something between pop, jazz, and funk. I'm one of the singers and I play the piano.

I also sing in the jazz/pop vocal ensemble Poema and write arrangements. Apart from that, I sometimes publish music on SoundCloud.

Photography* (2020-now)

I love being outside and often take my camera with me. While I'm traveling (oftentimes with Rico), I see the world in a much greater resolution than at home, and I like taking photos with that feeling. This page used to be my old homepage where I shared a small selection of my work.
