Since 2014 he started working for VMware Bulgaria, where every day, he adds a new small brick to the world's cloud infrastructure. His interest in Formal methods comes from his academic background and the observation that in recent years, software quality has become rather a matter of testing than being intrinsic to the software products. He still believes this can change.

For better or worse, with Java 9 and Jigsaw project around the corner (this time apparently for real), we finally need to stop pretending we can simply ignore the concept of modularity in Java! The problem is - modularity is NOT just some new framework! Neither it is a simple set of APIs! It's a concept that has been around for almost as long as the industry itself. It's ambiguous, it's hard to get it right and it has been widely misinterpreted and way too many times poorly implemented over the years. So in this talk I'd like to take a step back and reason about the fundamental idea of modularity in Java by asking three simple questions WHY? WHAT? and WHEN? And as it usually is with most simple questions, there are no simple answers and no universal solutions! So join me in this journey through concepts, ideas, frameworks, containers, classloaders, configuration files ... and see what's there for you!
