What I'm looking for

I seek technical-lead or senior Magento roles focused on architecting scalable, high-performance eCommerce platforms, complex integrations, and mentoring distributed teams.

I am a Senior Magento Developer with over 18 years in software engineering and more than a decade focused on full-cycle Magento eCommerce solutions for global enterprises. I hold Magento Certified Developer Plus and bring deep technical expertise across Magento 1/2, APIs, and performance optimization.

I have led large, cross-functional and distributed teams — including acting as technical lead for multi-site global platforms — and consistently reduced production issues and improved page load and checkout performance through architecture and deployment improvements.

My experience spans complex integrations with ERP, PIM, CRM, payment gateways, SSO, and government APIs, with a strong emphasis on maintainability, scalability, and DevOps collaboration. I am comfortable in client-facing roles and driving remote agile delivery.

I seek opportunities where I can apply technical leadership to architect and deliver reliable, high-performance eCommerce platforms while mentoring teams and collaborating closely with product and infrastructure stakeholders.
