About Me

With a foundation in systems-level thinking and a passion for real-world impact, I’ve helped keep complex platforms alive, added new features to legacy systems, and built internal tooling that scales. I thrive in environments that demand responsiveness, reliability, and clear communication.

I’m comfortable wearing many hats: developer, maintainer, sysadmin, and client liaison. Whether it’s debugging a legacy PHP module, optimizing SQL queries, or scripting in Python, I approach each task with diligence and accountability.
