What I'm looking for

I want to build scalable Magento/Adobe Commerce and Headless Commerce platforms where I can lead API-first GraphQL/REST development, integrate ERP/CRM and third parties, and optimize performance and reliability with a strong engineering team.

I’m a Senior Magento Developer with 11+ years of experience delivering scalable eCommerce platforms using Magento and Adobe Commerce, with 16+ years overall in PHP development. I specialize in Headless Commerce architecture, Magento GraphQL API development, and custom module development—building high-performance backend systems that stay reliable as business complexity grows.

In my recent role as a Technical Lead (Magento) at Embitel Technologies, I led enterprise Magento / Adobe Commerce architecture and implemented headless solutions through Magento GraphQL APIs. I’ve developed multiple custom modules, extended GraphQL schemas with queries/mutations/resolvers, and implemented event-driven architecture using plugins (interceptors) and observers, while optimizing API performance, database queries, indexing, and caching. I also integrate ERP/CRM and third-party services (including SAP/custom ERP and payment/logistics systems) to support product, order, and inventory synchronization across multi-store and marketplace (multi-vendor) environments.
