I proposed to rewrite an old project on Angular/CoffeeScript/ruby on rails to Preact with SSR and as a result, got flexible code which ready to add new features. For clients, it gives less traffic for JS/CSS (On angular it was 2MB but after migration 352kb), the encapsulated widget in web-components with Shadow-Dom
I worked on creating the architecture for a new product in the company, which was later successfully launched next team after me.
Personally created a new upsell product for the existing one, that generated the company additional 35% of revenue
I do not expect to work with Angular
