My background includes C#/.NET, RESTful API design, MS SQL optimization, Azure DevOps pipelines, and implementing security best practices (OWASP, CompTIA Security+). I focus on clean architecture, testing, and maintainable code while collaborating cross-functionally to integrate software with existing infrastructure and scale high-volume systems.
