John has over 35 years’ experience working with enterprise IT systems in various roles including development, design and architecture. He has used this experience to create a suite of products to address lack of access to complex test systems which is a major bottleneck in the roll out of new products and the on boarding of external customers in large enterprise organizations. The result of this is Ostia’s Portus EVS technology which enables the creation of clever, simulated test systems and sandboxes on demand. These sandboxes facilitate the modelling and testing of new standards for Open Banking and PSD2, and implementation of new technologies such as Blockchain.
