Financial and Banking Systems Background

Background

After completing my degree in Information Systems and Artificial Intelligence, I started my career at First Direct within their Internet Banking team, building and deploying back-end service capabilities in C, C++ and Java. Since then I’ve been able to stay technical, not only maintaining a solid coding and DevSecOps element, but also with a keen focus on good architecture, design, and best development practices. Recently I was responsible for the development of an FCA regulated online finance platform, designed to support on-premise, cloud-first and hybrid deployment options according to client requirement.
