About Lívia
I build things that work and things that don’t break. I’m a software engineer with a strong focus on web development, APIs, and security, and I love turning complex problems into clean, reliable solutions.
I’ve worked on everything from dynamic web apps to security analysis and bug hunting, always with an eye on performance, scalability, and “what could go wrong if this goes to production?”. My goal is simple: help clients ship better software, sleep better at night, and avoid unpleasant surprises after launch.
