01 — About
Building what
people touch every day.
I'm a Senior Mobile Software Engineer with a deep focus on React Native. My path into tech wasn't conventional — I started in operations and business at companies like Dow Chemical and Procter & Gamble before making a deliberate pivot into software engineering.
That business background gives me a perspective most engineers don't have: I think about the product, the user, and the system — not just the code. Today I build mobile platforms at scale, design testing architectures, and create developer tools that make entire teams more effective.
