What I'm looking for

I’m looking to lead enterprise WordPress engineering—shipping scalable architecture, Core Web Vitals performance, and CI/CD automation—while driving measurable productivity gains through thoughtful AI enablement and strong engineering practices.

I am an engineering leader with over 12 years of experience specializing in high-performance web applications, modern frontend frameworks (React, TypeScript), and robust backend/CMS architectures (Object-Oriented PHP, Python, WordPress). My background sits exactly at the high-leverage intersection of Core Engineering and Growth/MarTech infrastructure, making me a unique asset for your client briefs in the SaaS, Fintech, or digital consultancy spaces.
