About

I'm a senior full-stack software developer with over 7 years of professional experience at enterprise companies including Global Payments Inc. and Homes.com (CoStar Group). I'm now available for contract and part-time work to help small and medium-sized businesses access the same level of expertise.

My expertise spans the full development lifecycle, from architecting scalable backend systems in ASP.NET and .NET to building responsive, modern frontends with React, Angular, and TypeScript. Working at enterprise scale has taught me to write clean, maintainable code and deliver pragmatic solutions that solve real business problems.

Whether you need a reliable developer to build a new feature, fix critical bugs, improve performance, or develop internal tools from scratch, I bring enterprise-grade expertise with a practical, no-nonsense approach. I'm available for evening and weekend engagements, communicate clearly, and prioritize solutions that work.
