LEAD ANGULAR DEVELOPER @ DXC

Jan 2020 - present

Led the development of an Angular backoffice app for one of the biggest car manufacturers in Germany.

Highlights:
- wrote a script, that queried GitHub for all OpenAPI microservice specs, linted and merged those and then called the openapi-generator-cli to generate Typescript interfaces and Angular services so the developers didn't have to manually create those themselves
- introduced Typescripts "strict" flags and Angular's "fullTemplateTypeCheck" and refactored the whole app to be compatible
- created a generic, reusable datatable component with a corresponding datatable service that encapsulated common logic like editing rows, API queries and UI behavior to make creating new views with a datatable (of which there were a lot) much simpler

- Typescript + Angular 8 to 10
- Karma + Jasmine (unit tests)
- Protractor (automated e2e tests)
- Bootstrap 4 + PrimeNG
- NodeJS
- OpenAPI tools
