I've been a web developer for over 6 years. I enjoy the challenges of both backend and frontend development. In general, I like focusing on writing predictable APIs, from the lowest level all the way up to a system's design - I believe having such a solid foundation is the best way to improve the overall quality of the code written by a team.
I stay up to date by constantly trying new technologies, attending and talking at local meetups and keeping in touch with the community in general.
