What I'm looking for

I'm looking to continue building backend and e-commerce systems, solving complex production issues, and expanding my work with modern JavaScript, React, and Laravel in remote international teams.

I've built and maintained enterprise PHP-based B2B e-commerce platforms at Content Management and Solutions, supporting more than 100 client-specific implementations and over 500 daily transactions.

I developed modules for product management, checkout, pricing, shipping, reporting, and order processing for European and UK clients including Realdolmen, Click2Shop, Systemat, Proximus, Lunch Garden, and Shopmate. I also integrated product, pricing, order, payment, and analytics APIs, including the HiPay payment gateway and Google Tag Manager.

I'm experienced in SQL Server database maintenance, query optimization, legacy-system improvements, debugging, and production support. Through freelance work, I'm continuing to build with Laravel, JavaScript, WordPress, OpenCart, AWS EC2, Route 53, and React.
