In this session I will take you through the entire process of application development and how to avoid possible issues on each stage. In a modern world turning an idea into working piece of software is a very complex process, and in this presentation, I will unlock the best practices and the essentials based on real world stories from my practical experience. During a session I will give you a sense of Typescript, ECMAScript 2015+, JavaScriptServices, application performance management and how to make your life easier with some Node.js based tools.
