Mark is Lead/Senior Developer at Paybreak, a fintech company based in Altrincham near Manchester, UK.
He has worked in the computer software industry since before symbolics.com was registered as a domain name, before "cyberspace" was first mentioned in fiction, when Linus Torvalds and Rasmus Lerdorf were still at high school, and Mrs. Zuckerberg had yet to give birth to a bouncing baby social network enabler; and has developed for the Web in many different languages since the days when the Tim Berners-Lee's creation comprised less than 1,000 sites.
Over those years he has contributed to a number of open source projects: including a minor submission to PHP's SPL. Currently he is coordinator and lead developer for the PHPExcel library, and a coordinator and developer on the PHPOffice library suite. Most recently, he has been working on new datastructures such as Tries, Quadtrees and Matrices; hoping that he'll eventually be able to get them included in SPL.
His particular interests include PHP integration with office suites, Generators, Textual analysis, Geodata and geographic information systems, and "big data" and data analysis.
