This talk is all about improving and cleaning up your legacy code base and eventually pay off all (if not most) of your technical debts.
I'm a senior Ruby developer from the Philippines. I have been an active part of the Ruby community there - I have worked as the RubyConf PH website maintainer for a few years. I have since moved to Perth to work with Rent.com.au as the lead developer and the CTO and co-founder of Beanbag Entertainment. I also mentor people on the side via exercism.io and some boot camp websites as part of paying it forward back when I was mentored by one of my former bosses.
