Numbers first, then AI.

I turn business questions into numbers, processes and tools. Six years as co-founder of JJLab UG taught me to think a company through in numbers, and what a tool has to earn inside it. B.Sc. Business Informatics from Leuphana University Lüneburg.

Selected work

Thesis: Liquid Neural Networks vs. classical models
Benchmarked 11 liquid-neural-network variants against 8 established baselines on ten years of daily AAPL, JPM and SPY returns, with 120 comparisons corrected for multiple testing. Result: no significant advantage in any of them. A clear no, measured properly, is worth more than a flattering chart. Graded 1.0.

vertigo
An AI system that runs without me. Every morning it checks my investments against the reasons I wrote down for holding them, and it marks every line as either calculated from data or written by a language model. Numbers are never generated. Scheduled on GitHub Actions, running daily.

job-triage
A daily pipeline that reads job boards for me, scores every posting against a written profile with Claude, and puts the few worth a look on a Notion board. My verdicts teach the next run: a stop-list runs in shadow mode before it acts, and a scoreboard measures which searches earn their place. It never applies anywhere.

JJLab UG
The company I co-founded in 2019 as a two-person founding team and ran for six years alongside my studies. We built ArtSlide and later rooted: digital marketplaces connecting local makers of home goods with customers. I owned finance, analytics and product: business plans and financial models, two friends-and-family funding rounds, every annual statement filed in-house, and the freelance customer-success support we brought in for 2023 and 2024.

About

I'm happiest where business questions meet numbers: a financial model, a strategy paper backed by figures, a KPI that changes a decision. AI is how I make the recurring work behind it run by itself.

In 2019 I co-founded JJLab UG, built it alongside my studies for six years, and was responsible for finance, strategy, product and analytics: business plans, financial models, the marketing strategy and every annual statement.

I completed my B.Sc. in Business Informatics at Leuphana University Lüneburg in 2026. My thesis compared liquid neural networks with classical forecasting models on financial-market data and was graded 1.0 (read the PDF). The answer to my research question was a clean “no”, and I'd rather report that than show a flattering chart.
