He was the principal developer of Modelibra (http://www.modelibra.org/) tools and frameworks for model-driven development in Java. Currently, he is developing the dartling framework for the design and code generation of Dart models. His projects are on GitHub (https://github.com/dzenanr), where he is considered a Dart expert (http://osrc.dfm.io/dzenanr). He writes about his projects on the On Dart blog (http://dzenanr.github.io/). His courses are available on On Dart Education (http://ondart.me/). He markets his Dart efforts on the On Dart G+ page (https://plus.google.com/+OndartMe).
