I help eCommerce businesses build, fix, and scale systems that others struggle with. With 10+ years of experience, I specialize in OpenCart, complex API integrations, and automation — the kind of work that goes beyond basic website development. Most of my work involves: • Fixing critical issues that other developers couldn’t solve • Building custom OpenCart modules and extensions • Integrating third-party APIs (payments, shipping, CRMs, etc.) • Automating business workflows to save time and reduce manual work • Improving performance and stability of existing systems I’m not here to build basic websites — I focus on solving real technical problems and delivering reliable, long-term solutions. Recently, I’ve also been helping businesses integrate AI-powered features and automation into their platforms. If you’re looking for someone who understands systems deeply and can take ownership of complex tasks — I’m ready to help.
