Pim de Wit; Frontend Developer, Creative Technologist

I am a web developer from Amsterdam, currently based in London. For over 15 years I have been building interactive experiences, often leaning towards the creative-tech side. I particularly enjoy thinking about software architecture, demystifying performance pitfalls, and figuring out the smoke and mirrors behind complex graphics.

Jordan District 23

Jordan District 23, Developed w/ Stink Studios, for Nike Air Jordan

I prototyped and built games for a week-long livestream on Twitch that reached 100.000 concurrent viewers/players through a Twitch extension. The work involved physics, anti-cheat detection, complex dynamic rigging animations and armature systems, and lots of fun with graphics. We collaborated closely with the team at Twitch to push the boundaries of whats possible within the Twitch Extensions platform.

Stack: Three.js, r3f, TypeScript, React

Google DeepMind

Google DeepMind, Developed w/ Google Brand Studio, for DeepMind

As a UX Engineer it was my responsibility to rebuilt the new DeepMind website from scratch. The goal was to ship code really close to the metal with a focus on performance and scalability. We put our focus on simplicity, accessibility, and general best-practices to build the foundation for a site that constantly evolves due to the nature of the topic (AI).

Stack: HTML, CSS, TypeScript, Python, Django, Jinja2

Diriyah

Diriyah, Developed w/ Journey

A digital twin of an entire city rendered in the browser using WebGPU and Gaussian Splatting. I built the LOD (level-of-detail) system, memory management, and culling pipeline to handle splats ranging from 2MB to 40MB per building. The challenge shifted from graphics to performance: what to load, what to cache, and what to unload as the user explores.

Stack: WebGPU, React, PlayCanvas

Loewe x Howl’s Moving Castle

Loewe x Howl’s Moving Castle, Developed w/ Stink Studios, for Loewe

This was an amazing opportunity to work with Studio Ghibli. I have created several WebGL-powered games that received direct art-direction feedback from the Ghibli team.

Stack: TypeScript, WebGL, Pixi.js, React

Pyramids of Meroë

Pyramids of Meroë, Developed w/ Google Brand Studio

Pyramids of Meroë tells the story of the Kush Empire in Sudan. We had a drone-team in Sudan capturing 3TB of footage for photogrammetry, which we then optimised to 3MB for the web.

Stack: HTML, CSS, TypeScript, WebGL, WebXR
