The story behind the code
About Me
My journey into software engineering didn't start with a compiler — it started with people. Working as a Service Analyst, I learned to listen: to users, to processes, to the gaps between what systems promise and what people actually need.
That foundation shaped everything that followed. As a Quality Analyst, I developed a rigorous mindset — understanding that great software isn't just functional, it's trustworthy. I learned to break things intentionally so that, when they mattered most, they wouldn't break at all.
Today, as a Software Engineer, I bring that rare combination to every project: deep user empathy, a quality-first instinct, and the technical skills to build full-stack solutions. I work across React, React Native, Python backends, and AWS infrastructure — always with the same question in mind: does this actually work for the person using it?
