Native Mobile Apps with Flutter (2019)

In the summer of 2019, I built native iOS/Android apps with Flutter to validate a business problem. Flutter is Google's cross-platform UI toolkit. I used Google's cloud service Firebase for login, No-SQL database, and file storage. I also built my own back-end with Java, JHipster, Spring Boot and Angular. This video has the details.

Progressive Web App (2019/20)

At the end of 2019, I built a progressive web app (PWA) to speed up app development. A PWA uses the "Service Worker" in a browser to install on your device and cache data. I used [Google Workbox]( for this, but developed my own offline storage solution in the browser. I built my back-end with Java, JHipster, Spring Boot and Angular. This video has the details.

I have my own blog at where I help Java developers build better projects faster. Here is the first part of my JHipster tutorial. My editor, Michael Duda, performed some light editing on it (such as some rephrasing here and there).
