I test software. Including mine.
QA by trade. Developer after hours. Vibe coding, but under adult supervision.

01About
From restaurant systems to international bugs.
I started by implementing restaurant automation systems — convincing software, printers and kitchens to cooperate. Then came ERPs, a developer role at Banco Mercantil and, today, QA work with international teams. The job is still mostly the same: understand the system and find the bug before the customer does.
