About

Let's pair program in (mainly) Kotlin! Subscribe to get a weekly fix of pair programming with an experienced engineer. Learn how I approach coding, problem solving, debugging and project management. Watch me try to figure out AI. Marvel at how often things fail the first time, but quickly get better. I've been programming since 1981, and a professional software developer for more than 30 years. I've been lucky enough to have some excellent teachers over the years, but I remember what it was like to work in an organisation where people didn't share my passion or expand my skills. So, now that I'm retired, it's time to give back. Advanced Kotlin with Extreme Programming (XP), covering Java to Kotlin, Test Driven Development (TDD), Refactoring, Object Oriented (OOP) and Functional Programming (FP). Co-author with Nat Pryce of the O'Reilly book Java to Kotlin - A Refactoring Guidebook. Show your appreciation though the medium of PayPal - https://www.paypal.com/paypalme/DuncanMcGregor
