I find bugs before your users do. I break things on purpose so nothing breaks by accident.
QA Engineer with 5+ years of experience breaking things professionally. I specialize in finding the bugs that nobody else can find — the ones hiding in edge cases, race conditions, and that "it works on my machine" territory.
My mission: ship software that users can trust. I've prevented thousands of bugs from reaching production across fintech, e-commerce, and SaaS platforms.
