At Deloitte, I lead front-end development and maintenance for Canada Post's multi-seller marketplace, built on Adobe Commerce (Magento 2) and integrated with Mirakl. I deliver feature enhancements and UI fixes across shopping and checkout, and provide live production support.

Earlier, I designed, developed, and maintained e-commerce websites including www.mash.pt and www.motocinquenta.com.
