Now: tooling for agents, infra for clients.
Full-time at Grensesnitt AS — a consultancy that lets me jump across client engagements; the breadth is the whole point. On the side I’ve been building tools that sit between humans, AI agents and the messy systems they touch.

RuneJS — building yesterday’s internet from scratch.
A TypeScript stack for the mid-2000s RuneScape protocol. Joined as the second contributor on runejs/server in late 2019 and have been co-leading the org ever since — game loop, content APIs, JS5 cache, login & update servers, and the client work that sits on the other end of the wire.

Map maker, cartographer of made-up worlds.
Cut my teeth in the Warcraft 3 modding scene — JASS, then Lua, then helping move things over to a TypeScript → Lua workflow. Most of the toolchain that made it possible (w3ts, war3-types, war3-transformer, JassToTs, WC3MapTranslator) is the work of a small community of map authors I’m glad to be a part of.
⚔
Ground-up rebuild of the cult-classic WC3 map. Replaced years of tangled JASS with a typed code base, a deploy pipeline, and an active player base on maulbot.com.

A ready-to-clone TypeScript template for new WC3 maps — build pipeline, tooling and the type definitions wired up so authors can skip the yak-shaving and start writing gameplay.

⚗
Translators that round-trip between WC3’s legacy formats (.j, .w3x, .slk) and JSON so they can live in Git, in CI, and in modern editors.
