Experience

  • Awesome Grocery App
    https://awesomegroceryapp.netlify.app/

    During the lockdown, I developed this small app to practice my vanilla JavaScript skills. I followed the object literal pattern, using the object literal encapsulate data, enclosing it in a tidy package. This minimized the use of global variables, which can cause problems when combining code.

  • Movie App
    https://awesomemovieapp.netlify.app/

    This is a React-based movie app that fetches movie information using the OMDb API, a RESTful web service. The user needs only to input the movie name in the search field. This app was built within a couple of hours as a project challenge.

  • CompareTheMarket Mobile Homepage Redesign

    I developed the variant UI for CompareTheMarket, which was tested as an alternate design to the existing one. It was developed with vanilla JavaScript and deployed through Optimizely to validate the hypothesis.

  • Sixt.de Listing Page Redesign
    https://drive.google.com/drive/folders/1wmtEQgKn-jmm-VjxRxXtHTeRAYHahX5c?usp=sharing

    Using JavaScript, this design variant was developed within a day for the Sixt.de listing page. It was tested thoroughly through Optimizely against the current design. The results validated the hypothesis.

  • Weather App

    This a very simple React app that shows the functioning of weather API and provides information about weather based on user input. The background and imagery are dynamic. It was done using state React Hooks.
