For my external PR I worked and still am working on a library project that my professor maintains outside of Seneca called Filer. Filer is a drop-in library that works like node's fs module but for browsers. The issue I was working on was making a migration of parcel 1 to parcel 2.

  • GitHub repo bootswatch

    Themes for Bootstrap

    Project mention: What am I learning? | | 2021-10-08

    As a piece of concrete advise, you can use something like Bootstrap, which is already highly theme-able (almost all React component frameworks are highly theme-able, but Bootstrap can be themed with a simple link tag in your HTML),, so that you can have a consistent UI, while you focus on learning the ropes of React. Just becareful that some bootstrap elements might need jquery, which is why reactstrap or react-bootstrap exist.

  • GitHub repo 30-seconds-of-interviews

    A curated collection of common interview questions to help you prepare for your next interview.

    Project mention: Frontend Developer Interview @Zalando | | 2021-03-31

    I can't give you Zalando specific prep tips, but general prep tips from my experience with bigger companies that still have this startup-ish mentality. Make sure that you understand the details of JS (event loop, promises, etc.) and if they mentioned the tech-stack (vue, react, whatever) make sure you thoroughly understand them as well. And expect questions about your cultural fit, so have a genuine interest in the company (google it) and in a good work environment (knowledge sharing, pair programming, mentoring). For system design, be sure to think of CI/CD, testing and monitoring. And if you don't know something, be open about it and mention that you are willing to learn, don't make something up or try to cheat, it will be noticed. And remember its a two way street, ask questions. i like this resource for interview preparations a lot: 30-seconds-of-interview
