🚀 Legacy Application Modernization Expert | Azure Solutions Architect | Full-Stack Developer 🏢 Most businesses aren't starting from scratch. They're running systems that have been supporting their operations for years, sometimes decades. Those systems matter because employees, customers, and day-to-day operations depend on them every single day. 🔄 The challenge isn't building something shiny and new.

I understand those challenges because I've helped organizations navigate them successfully. My focus is helping businesses upgrade, migrate, and modernize legacy applications built with ColdFusion, PHP, Drupal, and other enterprise technologies.
