Digital Insurance Group
Senior Mobile Developer
I joined this company to help it to build an insurance product for banks & insurance companies. I helped to build a boilerplate which consist of mobile, web, admin apps. It can be created pretty quick for a new client. The idea is: let's say you have a bank/insurance company and you want to have a mobile/web app to sell your product, so there when the DIG comes into play. It gives you mobile/web/CRM apps out of the box, all you need to do is to put your logo/styles/translations. This is what I call boilerplate. Our stack is quite "new": React, Relay, React-Native, GraphQL. We write tests with Jest & Enzyme. I also wrote some tests for GraphQL & Relay, which eventually help us to keep backend sync with front-end. Now I am dedicated to building a mobile app for Zurich.Connect Italy. I used to work in a team on building the boilerplate but now I am working alone(on front-end).
