Daniel Marulanda
Curious by nature. Skeptical by default. I like understanding how things work and making useful things.
I’m Daniel Marulanda, a software engineer based in Medellín, Colombia. I work across product, code, and the systems that connect them, and I write in English and Spanish.
I co-founded Dondo, a Colombian app that began as digital barter and later became an AI product for merchants. The press links below cover different stages of that work.
This site is where I share what I’m learning while building: decisions, tradeoffs, mistakes, and the occasional result worth keeping.
