About

Technical work shaped by systems thinking and practical delivery.

My background began with hands-on software development using PHP, MySQL, JavaScript, and web frameworks. Over time, my responsibilities expanded into software architecture, project planning, team leadership, client communication, infrastructure management, SEO, digital marketing, and business process improvement.

I have led developers and designers, supported international client projects, managed production websites and servers, customized Shopify and WordPress platforms, integrated APIs and payment systems, and delivered restaurant ordering and retail technology solutions.
