Hi, I’m Diego, a software engineer and diver.
I'm from Colombia, based in Spain.
Working across Europe and Latin America.
I currently work as a Software Engineer contractor in the automative industry.
Here I share my tech experiments and projects across eBPF, distributed systems, performance engineering, backend development, and AI. I also document my journey through ocean expeditions and conservation.
