Paul M. Jones is an internationally recognized PHP expert, working in that language since 1999, and programming in general since 1983. He has held roles from junior developer to VP of Engineering in all kinds of organizations (corporate, military, non-profit, educational, medical, and others). He is a regular speaker at technical conferences worldwide. As the author of Modernizing Legacy Applications in PHP and Solving the N+1 Problem in PHP, Paul takes a special interest in high-quality, high-maintainability coding practices. His leadership on the Aura for PHP project reflects this interest, along with his white paper on the Action-Domain-Responder pattern. Among his other open-source work, Paul was the architect of the Solar Framework and the creator of the Savant template system. He has authored a series of authoritative benchmarks on dynamic framework performance. He was a founding contributor to the Zend Framework (the DB, DB_Table, and View components). Paul is a voting member of the PHP Framework Interoperability Group, and was the driving force behind the PSR-1 Coding Standard, PSR-2 Style Guide, and PSR-4 Autoloader recommendations. He was one of the first elected members of the PEAR Project. He was also a member of the Zend PHP 5.3 Certification education advisory board, and wrote some of the questions on that test. In a previous career, Paul was an operations intelligence specialist for the US Air Force, and enjoys putting .308 holes in targets at 400 yards.
