About

Senior Software Engineer with hands-on experience modernizing complex systems and delivering large-scale, user-focused platforms. I was the first engineer hired onto the IRS Direct File program through USDS, where I helped design and build a major new taxpayer service from the ground up. I work in an AI-native way — aggressively using AI tools to move faster, cut repetitive work, and focus engineering effort on high-value problems. This approach has let me take broad ownership and consistently deliver clean, maintainable solutions that improve both user experience and team velocity. I’m also a startup founder who built a company to help veterans transition into civilian careers. That experience sharpened my focus on building practical tools that solve real problems for real people. I’m looking for opportunities where I can apply strong engineering practices and AI leverage to build impactful software — whether in government modernization or the private sector. What changed:
