I have proven experience writing scalable Web Applications using many technologies, tools and languages to identify, build and optimise a variety of products. I have plenty of experience managing the deployment of code in a highly scalable environment, with Bamboo, Jira, Stash and Git.
Modern websites should be Smart and understand the device they are being viewed on. There is no longer a need for separate versions of a site specifically targeted at mobile devices, they should be aware, and respond dynamically, just like this one.
Over the years working in such high availability and large scale environment, I've built up a significant amount of knowledge both in development techniques and also in using and configuring essential services required to scale. Below is some (but not all) of them.
I write clean, readable and efficient Object Oriented PHP. I don't mind writing documented either.
Data Storage + Caching
I know how to get the most out of MySQL (+ Maria DB), and when to use Memcache and Redis for caching.
I wouldn't be very good if I didn't know HTML (which I do), I use HTML5 + CSS3 where I can!
