ABOUT ME

I am a senior software engineer with experience in Public Services and Insurance and Fintech startups specialising in telematics, behavioural profiling and e-commerce. I am passionate about delivering well-tested and good quality code and I am a fast learner. I am a good communicator and am happy to resolve problems as a team. I like simplicity in code that others are happy to read and extend. I am interested in developing my knowledge of modern programming languages and infrastructure tools and am keen on developing skills using modern javascript frameworks including React and Vue.
