I'm a Senior Software Engineer with 11 years of experience building scalable full-stack and distributed systems using technologies like React, TypeScript, Node.js, Python, and AWS. Throughout my career at Uber, Intuit, and Gusto, I've led projects that improved performance, reliability, and developer productivity while supporting products used by millions of customers.

I'm looking for opportunities where I can take ownership of meaningful technical challenges, collaborate closely with cross-functional teams, and help drive both product and engineering success. What sets me apart is my combination of strong technical depth, product thinking, and a track record of delivering business impact through software.
