Projects & experiments
Moatfold
A native Mac app for value investors. It rebuilds your portfolio history from broker exports, computes returns in code, benchmarks them against a world index using your real deposit dates, and runs Claude-based research on those verified numbers. Everything stays in a local folder, and it can use your own Claude key or a local model via Ollama.

Portfolio for Zuzi Knaze, an interior designer in The Hague. First built with Gatsby in 2016 and rebuilt since on Astro: three decades of apartments, houses, furniture and objects, organised by decade, with generated thumbnails and PWA icons as part of the build.
