Hey, I'm dain

a design technologist and full-stack AI engineer at Tangible.

I got my first computer (a basic 386 PC) in the early 1990s, after years of bothering my cousins if I can use their Commodore 64. I started tinkering with my computer right away (motivated by a mix of curiosity and the need to tweak config.sys and himem.sys to get video games to run in DOS with limited hardware) and did my first programming experiment building an interactive periodic table in Borland C++ sometime around 1996.

At the end of the 1990s I got into web design and development by creating websites for small businesses using Macromedia Flash for a bit of extra pocket money. My first proper software development job was through my university internship at a digital advertising agency called Carnation (now part of Wunderman Thompson Budapest) in 2005 which I got through a competition winning essay about the future of the web.

I've been living in London, UK since 2007 (with shorter periods in Malmö, Sweden and Amsterdam, Netherlands) where I worked at ustwo from 2007 and Beryl Bikes from 2018, before joining Tangible in 2024.

Outside work I'm a husband, dad of two, and neurodivergent — which might explain the unquenchable curiosity that's been a thread through everything above. These days it pulls me toward metacognition and epistemology, trying to understand how we think and how we know what we know. Language models have become a fascinating tool for exactly that, even as I try to reconcile their potential with how taxing they are on the environment in their current form. That same restlessness drives me to question the assumptions we build our lives around, from our relationship with growth and consumption to how we connect with the natural world. I try to share what I learn through open source — my small contribution to counterbalance the corporatisation of life.
