About me

A comprehensive profile of how Carlos thinks, executes, and turns quality into an operational advantage.

I have been building quality within product teams that cannot afford to fail for over 6 years. I specialize in performance testing, E2E automation, and QA strategy for applications scaling to millions of users.

My approach combines deep technical judgment with business clarity: I don't just find bugs, I design systems that prevent them from appearing. I work with teams in LATAM and North America to launch more reliable software.
