Steve Purves (Tenerife, Islas Canarias) @stevejpurves

Steve Purves, Senior Software Developer at Expero, describes himself as an engineer first and foremost. He is comfortable working full-stack, cross-platform in a range of languages and is happiest when there is some mathematical or scientific analysis sprinkled in. He graduated in electrical engineering specializing in signal and image processing, which he took into the scientific computing field in the Oil and Gas industry.
During that time his work was largely split into three: development of low-level number-crunching libraries (C, C++, CUDA) and the cross-platform desktop application with 3D visualization to drive it; applied research in signal processing, numerical analysis algorithm development for 3D seismic analysis, during which he was an IEEE journal geek; and finally management of R&D and Product development teams as CTO, championing practices like TDD, BDD and Agile to get it done.
Around 5 years ago, the excitement of daily binary builds wore thin and Steve got hooked on building applications for the web, starting out with web-desktop integration work for seismic analysis on the iPad. Since then activities have included working on full-stack web applications, with and without desktop integration, for startups in sectors such as Dental, TV Production and Software Micro-Consulting.
Today, he builds reactive web applications with Expero, which feeds his desire to learn and work on industrial-strength projects. Steve waits patiently, with ES6 JavaScript and Jupyter Notebooks at the ready, for the imminent explosion of scientific computing on the web.

During this time he worked on everything from large enterprise systems to smaller, cutting edge research and development projects. One of the most rewarding parts of each of these projects was the time spent collaborating with the customer.
As Ted’s career continued, he moved on to an oil and gas startup and continued to dig deeper into the data side of software development, gaining an even deeper interest in how databases work and how to eek as much performance out of them as possible. During this time he became interested in the application of graph databases to certain problem sets. Today, at Expero, Ted enjoys putting his deep knowledge of transactional graph computing to work as he helps customers of all types navigate the burgeoning property graph database landscape.
