Alphapoint
https://alphapoint.com/Initially provided support for an existing ecosystem of apps, three presentational apps, templates, and two shared libraries.
All of this were merged into a new standalone app. I proposed and implemented a CSS architecture, using BEM for styling components and CSS variables for template theming (this would even be used on third-party libraries by retrieving their values with JS). I also proposed and implemented the creation of an internal components library. This were to be presented on a style guide page that would be used as a reference for component usage. Icons were svg files and used as svg elements so they can be styled with CSS thus maintaining their ability to be styled with CSS.
I Implemented all sorts of common components, image uploaders, and a Redux-based snackbar to display messages, sidebars and so on. I implemented internationalization through redux-i18n and created scripts for handling corner cases such as translating config files texts.
I reviewed PRs as well as ensured UX consistency and overall JS consistency (included prettier as a pre commit hook). I created and supported unit tests using Enzyme and Jest.
