Hi, I’m Diego, a software engineer and diver.
I'm from Colombia 🇨🇴 living in Barcelona 🇪🇸.
I currently work as a contractor Software Engineer at Goodyear.
Here I share my tech experiments and projects across eBPF, distributed systems, performance engineering, backend development, compilers, containers and AI. I also document my journey through ocean expeditions and conservation.
