Lead Full Stack Developer • Systems Engineer • DevOps Integrator

Building reliable software, modernizing legacy systems, and automating everything possible.

About Me

I'm a full stack developer and systems engineer with experience spanning web development, Linux and Windows administration, DevOps, networking, automation, database design, and industrial CNC software integration.

I enjoy solving difficult technical problems that cross traditional job boundaries. Whether it's writing PHP, troubleshooting DNS, building Docker infrastructure, automating business workflows with PowerShell, optimizing SQL queries, or integrating decades-old software with modern web technologies, I like building practical solutions that last.
