Hello from Zaragoza. I'm Octavian. I build products from the interaction details down to the code. I've been shipping commercial software since I was 16, starting with core systems for Winterbyte's Unity tools.
I co-founded Infima Games, building UE5 tools and supporting the developers who used them. At TwinMind I was Lead Web Engineer: the sole engineer on the brownfield React Native app, alongside a major rewrite of the web app. Most recently, I was Senior Product Engineer at Ojin, building agent customization, synchronized captions, interactive live-agent demos, and shared design-system tooling.
