rank: Staff engineer @ Seenons
specialty: AI engineering · building with AI · AI factories
base: Amsterdam, Earth
orbit: long-time builder of systems that hold under load
fuel: curiosity, hand-rolled protocols, and active hope 🌿
status: 🟢 nominal · always building something- AI engineering and AI factories. I build with AI every day and design the factory around it: agents and skills wired into real workflows, with the guardrails, review loops and tests that make AI-produced software something you can ship.
- Distributed systems from the metal up. Designed and built a full blockchain node: fork choice, RANDAO-style randomness, stand-in validators so proof of stake never halts, replay protection, mempool DoS limits, peer banning, headers-first sync.
- Languages and tooling, not only apps. A compiler (Lex + Yacc), a Lisp interpreter, concurrent channel primitives in Rust.
- Product engineering that respects people. Local-first, privacy-preserving apps where the data stays on the user's device.
- Over a decade of shipping across Rust, TypeScript, Ruby, Java and C++, now a Staff engineer at Seenons.
| Mission | Payload | What's on board |
|---|---|---|
| ⛓️ blockchain-rs | Rust | A cryptocurrency built from first principles: proof of work and proof of stake, RANDAO beacons, Merkle proofs, gossiping peers, and a web UI that explains every block. |
| 🔥 hearth | TypeScript · Claude | A local dashboard with Claude in a side panel, running the same agent skills as the terminal. |
| 🐦 murmuration | TypeScript | Starling murmurations as boids with topological k-nearest neighbours: emergent flight, simulated. |
| λ ttinylisp | JavaScript | A Lisp interpreter, small enough to read in one sitting. |
| 🧮 At-Compiler | C++ | A compiler built on Lex and Yacc. |
| 🔀 chann | Rust | Experimental multi-producer, multi-consumer channels. |
| 🗂️ repomate | Ruby | Keeps a whole fleet of git repositories in sync from one command line. |
| 🌗 mood-tracker | React Native · AI | A private mood journal whose data never leaves the device, turning each week into a reflection prompt for Claude. |
| 🙏 gratitude-trail | Web | A physical gratitude card with a QR code, growing an append-only timeline of everyone who holds it. |
