Dan Phillimore is a founder and software engineer with 14 years' experience building and maintaining PHP- and JavaScript-driven web systems, currently leading product and engineering work through his company Nytris. He spent the bulk of his career as a senior engineer on an accessibility-focused enterprise CRM, owning features, on-call support, deployments and deep-root cause investigations that routinely unblocked colleagues. Comfortable across the stack—Symfony, MySQL, SSE/Mercure and background workers—he has a track record of fixing thorny production issues (including RabbitMQ consumer stalls and Memcached auto-discovery segfaults) without full rewrites. An active open-source contributor, he’s improved Mockery’s handling of internal PHP classes and circular data structures to make testing more reliable. Based in Leicester, he pairs pragmatic engineering with hands-on incident response and a curiosity for practical DIY projects off the keyboard.

Mockery is a simple yet flexible PHP mock object framework for use in unit testing with PHPUnit, PHPSpec or any other testing framework. Its core goal is to offer a test double framework with a succinct API capable of clearly defining all possible object operations and interactions using a human readable Domain Specific Language (DSL).
