Neil Green

Nothing matters more than coding fast

As self-diagnosed “recovering technical team lead,” Neil has taken a sabbatical from the exciting world of architect/lead/manager to go back to what he loves - being a full time coder. In his own words, “The technical part wasn’t hard, it was having to say the same thing over and over expecting different results (incidentally the definition for both insanity and stupidity) that wore me down over time. I needed a break.”

Today Neil finds himself sitting comfortably in a dark window-less cubical, with no direct reports, no project schedule to satisfy, no political in-fights, and best of all a manager to keep all the non-code related cruft at bay. Though cruel and unusual, Neil has taken to walking into his manager’s office and declaring, “Now YOU have to deal with it all! Hahahahah!!!!” Incidentally, he has found that this never gets old.

Further abusing his new-found freedom, he has also been known to start conversations with, “If you’re not writing clean code we can’t work together - sorry, I’m getting too old to sift through garbage” and “I get it – you don’t write units tests. That’s cool. I’ll just delete everything you commit so we don’t have to suffer with your steaming pile of well-it-worked-when-I-tested-it.”

Most days will find Neil belting out code with his favorite HTML5 stack: CoffeeScript, SASS, Backbone.js, Underscore.js, Handlebars.js, jQuery, jQuery UI, and jQuery Mobile while muttering, “These kids today don’t know how good they have it.” When asked if he’ll ever do backend development again he replied, “If I look at another line of Java I may stab myself in the eye. I’m holding out until the world realizes it should just learn something else – anything else. I’m starting to not care which.”
