    ShippingEasy is an online comparison and booking engine integrated with leading courier companies and eCommerce solutions. The engine is used by the website and an external API. The API is used by third party developers and eCommerce platform connectors. It's integrated with over a dozen third party web services.

    • Started as the sole developer in a team of 3 people developing the first version of the shipping engine and website. I was also in charge of the architecture and development as the team expanded to over 20.
    • Implemented a number of complex third party web services (couriers, payment processors, insurance providers) using disparate web services (XML, SOAP, RESTful, non-standard) into a single platform. Wrote unit, functional and integration tests.
