I work at new mind | tellUs, a company that designs, builds and hosts tourism destination websites through the UK and Europe - built using a custom CMS and populated with product data using an in-house "Destination Management System".
I am the Team Lead for the CMS Team, which has three main areas of responsibility;
Use data from the CMS and DMS (and some third party services) to render a million page view a day quickly and efficiently (fairly vanilla C# code that is designed and tuned to work at scale).
My job has a great mix of research and guiding the technical direction of the company while also being very hands-on and writing a lot of code (not to mention planning, spec'ing and mentoring).
By night, I do more coding and writing, much of which you can read about on my blog: www.productiverage.com. I'm particularly interesting in the topics "performance" and "writing code that is unambiguous and expresses intent as clearly as possible". These are often seen as conflicting goals but that needn't be the case most of the time!
