Braden Marshall
Hello internet,
I’m Braden, a product engineer based in London, currently at Isembard , building software to orchestrate manufacturing across hundreds of factories.
Before that, I spent six years as a founding engineer and engineering lead at Attio , where we built a beautiful yet powerful CRM. Earlier roles took me to Thought Machine , Cleo , Contentsquare , and others via Theodo .
I studied Computer Science at Cardiff University , but I fell in love with software much earlier in life when I built and sold video game mods to thousands of Garry’s Mod servers and running communities for Minecraft .
Have a lovely day,
