Designing to impact the teams I work with as much as the users I design for.

Case studies

Cool everyday things I’ve been building with Claude Code to make life easier.

Sponsor check

An assistant that reads my LinkedIn job alerts, checks each company against the IND’s register of 13,000+ visa sponsors and emails me the answer, so I don’t waste time on companies that couldn’t sponsor me anyway.
Letterboxd × Cineville

A daily check that matches the films I’ve saved to watch on my Letterboxd profile against showtimes at my 12 favourite Amsterdam cinemas and emails me when one is showing (e.g. FilmHallen is showing Memento today at 19:00).
Loopd

A website where you search a song and see what it samples and what samples it (think Ice Ice Baby → Under Pressure), then jump to Spotify to listen to the songs. Built with Claude Code.

Principal Designer at Southern Glazer's

I managed Diego on HEINEKEN's eazle CX team from 2025-2026. He started Hotjar watch parties where designers, engineers, and the PO sat with real session recordings, then turned what we saw into bottom-navbar experiments and a quick add-to-cart for regulars who just needed to reorder fast. He was proactive without being asked, and the team's conversations got sharper because we were looking at the same evidence. I'd work with him again without hesitation.

Diego has shown ownership of the topics he's responsible for. He asks thoughtful questions and tries to understand things deeply rather than just executing tasks. The watch parties he organized were super insightful and well planned — a great example of how he brings the team together to learn and reflect. His structured approach and attention to detail make those sessions really engaging and valuable.

Diego's skills were an invaluable asset to the Toolkit Tribe [at Heineken]. With his patience and inquisitiveness, he was always looking to understand what drives and motivates our users. This curiosity rubs off on people around him, and that's how he managed to put UX at a prominent place in the minds of not only developers, but also analysts and architects, doing a great job educating our department so we can develop tools that are fit for purpose.
