One idea — say more with fewer tokens — compounded into five open-source products: a skill, a workflow, a memory layer, a terminal agent, and a fine-tuned model.

About

I build infrastructure that makes AI coding agents work better. Caveman optimizes agent output, Cavekit drives specification-driven development, and The Prompt Library gives agents structured access to production prompts — all open-source tools that share one thesis: AI agents need better tooling, not just better models.

I'm also a founding engineer at Stacklink, an enterprise RAG platform, and building Revu, a native macOS study app that applies spaced repetition and multi-agent AI to education. The common thread is systems that compound — retrieval that improves with use, review schedules that adapt to recall, agents that learn from specifications.

I study Data Science & AI at Leiden University, where I sit on the Education Committee representing students in curriculum development. I write about AI systems and indie development on my personal publication, Polder.

Currently

Caveman crossed 60,000 GitHub stars after hitting #1 on Hacker News — maintaining the codebase, triaging issues, and shipping new modes. Heads-down on Stacklink: building the incremental sync pipeline and hybrid retrieval layer for the TU Eindhoven Innovation Contest. Cavekit, Revu, and Polder posts in parallel.
