What I'm looking for

I am looking for senior engineering roles with technical leadership opportunities, impactful projects, and collaborative, quality-focused teams.

I am a Senior Full-Stack Engineer with over 20 years building web platforms and internal tools across commercial, educational, public sector, and enterprise environments. I focus on maintaining mature codebases, designing APIs, and delivering scalable backend systems.

I have led development teams, provided technical direction, and mentored engineers while also owning end-to-end projects as a founder and consultant. My recent work includes maintaining critical user and account management modules, improving PHP unit testing and reliability, and contributing to lightweight CMS and access-management tooling.

I balance hands-on backend development with client collaboration and project leadership, translating business needs into maintainable technical solutions. I seek opportunities to apply deep PHP/Laravel and JavaScript experience to impactful, high-quality software initiatives.
