#The Origin

+5 years of software development

Dev by day. Builder by night. Father of Cielo, husband of Jacques. I build my own projects in my spare time, because my 9-to-5 isn't enough to give my family the freedom they deserve.

After years climbing promises that never materialized, I realized no one is going to build my freedom for me. That's how Buscer was born: a public log of a dev with real responsibilities — debt, family, a day job, and side projects.

Technology with soul. Radical privacy. Family legacy.
