I specialize in WordPress, OpenCart, and Joomla, and I’ve delivered 150+ websites across diverse industries. I thrive in remote team environments, guiding projects from planning through deployment, and I focus on performance optimization, SEO, and scalable architecture.

Earlier in my career I worked in microelectronics labs and telecommunications, and I’ve led IT and advertising initiatives.
