I Graduated with my Masters from King's College London in 2014.
I would say I'm naturally geared more towards back-end design and implementation. My studies taught me some serious database, security and architectural concepts. Though, for the last few years I have focused more on the front-end, this was required of me being a solo web-developer.
When I started my first company, we developed Rails applications. These topics helped massively whilst undergoing the learning curve associated with changing to a completely new type of programming paradigm.
After my partner (the lead front-end developer) left the business, I found my productivity plumeted using Rails. My abilities with Server implementation meant I could make fully custom Wordpress installs. I underwent another learning curve whilst figuring out how to best leverage the theme/plugin based framework and the associated PHP coding. I can now build some very powerful Wordpress applications.
As a Graduate of King's, my education was a lot more Mathematical than that of some of my peers. This has meant that I am able to learn new languages and frameworks with some level of pace. I am able to call on my knowledge of the implementation of programming languages and paradigms, graph and compiler theory, data-structures, algorithm/database optimisation methods and architectural design principles to accomplish this.
