What I've worked on
A bit of this and a bit of that
Professional Experience

Fresqo
Tried solving the problem of finding a community. I defined a community as a low-liquidity group of people that regularly meets around a shared goal/interest/purpose.
People are seeking more offline social interactions. Loads of products solve for discovery, but not for enabling connection growth.
⚰️ We managed to hit revenue, but failed at validating a viable way to generate recurring revenue at scale from this problem.

Amplify
Joined at 0 code and only a company vision. Am in charge of building the Festival Companion App, which we launched with over 4 organizers and 10+ events. Had 200k unique users in the 2024 season with a peak of 70k users at the same time online. 0 downtime.
Built in an extremely lean team (1.2 FTE); delivering value fast.

Arby (HFT Arbitrage Bot)
A hobby project turned into a little 30% yearly ROI printer on low capital.
⚰️ German bureaucracy, taxes and the nature of higher slippage with higher capital ended the story.

Legal OS (now Flank)
- Set up all tech on which Legal OS raised €2 million seed round.
- Set up recruiting process and executed ahead of the seed round.
- Product had zero downtime during my time at Legal OS.
- Set up single-click deployment and migration infrastructure.

Pieter Pot
- Onboarded 3rd party owned development processes into internal development team.
- Main focus was the mobile app, but I worked on all the technical components of the company (backend, website, deposit management system).

StockAlarm
- Wore many hats; Fullstack development to customer support.
- Identified key strategic goals to work towards such as expanding outside of the US.
- Implemented the technology necessary to achieve goals focus on scalability.
- Worked on high-load low-latency infrastructure

Code.nl
- Helped to create endpoints using serverless tech for smooth user experiences on web-shops hosted through the Shopify platform.

Crunchr Planning
- Done dozens of user interviews as part of launching a new product.
- Performed 1:1's with 2 developers to have a healthy team.
- Developed as well because of small team (3).

Crunchr Preference
- Moved unmanaged team to outcome-driven development.
- Performed 1:1's with 2 different developers than above.
- Developed as well here, again because of small team (3).
Side Projects & Experiments

Producter
It's hard to have a single-source-of truth for Product Teams that doesn't grow to a mess. I set out to fix that.
⚰️ I didn't care deeply enough about the product to put in the energy required.

Who is Playing?
Why not listen to who is playing instead of read up on it? Makes picking a party for the evening much easier.
⚰️ Shutdown because SoundCloud closed it's streaming API.

MixMerger
Using the fact that songs appear in multiple mixes, you can create infinite mixes by merging where they play the same songs.
⚰️ Shutdown because I over-engineered the Fourier Transformations to detect overlapping songs. If I would pick this up again I would first mechanical-turk the tool.

Transcendance
VR allows you to truly be immersed with music. I created a prototype, released on the Oculus forums, which got picked up by one of the main VR youtubers back in 2013.
🦸 Since I was a student never intended to take it further, but the positive reactions made me consider this a success!
