I've been writing code all my life, and I have had the privilege of writing code professionally for almost fifteen years now. I've worked in Lotus Notes/Domino, PHP, LANSA, .Net, Java, and NodeJS with a focus on insurance applications and processing of large files transferred from carriers to providers and plan sponsors to carriers.
In my spare time I study all that important Comp-Sci stuff I missed by not getting a formal education. It is quite useful stuff when working with very large data sets.
