I'm a software engineer based in the UK with a focus on the web. I've been developing for the web since the early 2000s with extensive experience in PHP, HTML, CSS, Javascript and related technologies. I'm a Zend Certified Engineer, and graduated from the University of Kent in 2013 with a degree in Information Technology (including a year in industry).
My main area of work sees me involved with and responsible for the design, implementation and maintenance of the back-end systems of high traffic, business critical web applications. These have included financial software-as-a-service (SaaS) systems, payment processing platforms, internal business intelligence tools and monitoring systems.
I have an interest and growing experience with the supporting infrastructure and services of the modern Internet, ranging from network and server hardware to high-availability systems, databases and caching layers. I've been involved with designing and implementing networks ranging from small/medium sized offices to secure data centre networks. I also have extensive knowledge of many of the protocols underpinning applications such as DNS, HTTP and SMTP and how to operate them securely.
