What I'm looking for

I’m looking for a remote contract/freelance role where I can lead SAP Commerce/Hypes eCommerce delivery—owning architecture, secure API integrations, and payment gateway implementations, while mentoring teams to ship reliable enterprise-grade platforms.

I’m a results-driven SAP Commerce Technical Lead with 13.5+ years in IT and 7+ years of hands-on expertise in SAP Hybris Commerce (6.4 through 2105, CCV2, OCC). As an SAP Certified Commerce Cloud Developer (2023), I deliver enterprise-grade B2B/B2C eCommerce for global clients across the US, Europe, and India.

I lead end-to-end implementations, including Hybris modules like PCM, WCMS, Order Management, Promotions & Vouchers, Checkout, and Search & Navigation (Solr), plus Backoffice customization and OCC/API integrations. I architect secure integrations using OAuth2/API authentication, build RESTful services, and integrate SAP Commerce with external systems via PI/PO middleware—while implementing payment gateways like Worldpay, Klarna, PayPal, Afterpay, and Billdesk. From migrating ATG-to-Spring Boot microservices (with Kafka, Docker/Kubernetes, and GraphQL) to upgrading Hybris 6.4 to 2105 and upgrading search via Bloomreach, I consistently mentor teams, run PR reviews, and deliver reliable, secure commerce platforms.
