More than 20 years experience working hands-on with systems development – has been involved in all phases of large, and small, projects. Specialist in applied mathematics and advanced decision support: Particularly mathematical optimization and simulation, as well as quantitative financials.Functions well as a link between business and IT – understands the business needs and is able to find tools and technologies to deliver solutions.I write Java code - that's what I do - and I program a lot of maths using Java. Over the years I've developed an aptitude for writing scalable performant code. In fact, I believe, I wrote the fastest pure Java linear algebra library available. ojAlgo is the name of that code library. It also contains, just about, the only existing pure Java suite of mathematical optimisation solvers (LP. QP & MIP solvers).Nowadays there is a lot of talk about artificial intelligence, big data, machine learning and stuff like that. To do those kind of things you need fast and memory efficient maths code - that's what I do best!
