Edaqa Mortoray grew up programming. From interface design to scientific simulations, including video games and development products, he has coded a bit of everything. He is the author of the book “What is Programming?” and he runs a successful programming blog and a podcast. We talk with Edaqa about why every member of software development team should know who their user is and what their needs are. He then shares with us some good practices for defensive coding in this age of global users. When you are done with the episode, and if you want to hear more about the user-focused software design, make sure to watch Edaqa’s class on Skillshare.

According to Evgeny Demchenko, technical debt and financial debt have many things in common - if used strategically, they accelerate growth, if not repaid diligently, they hinder it.

He is specialized in building startups, managing complex systems and refactoring code. We talk with Evgeny about his passion for refactoring and he shares with us his technical debt philosophy, his workflow and his favorite tools of the trade.
