2020 - PRESENT
Mira Beauty
  • Led a team to build and maintain the web app of an eCommerce firm primarily catering to female audiences in the beauty industry.

  • Participated in scoping, estimating, and risk management efforts for better product delivery.
  • Owned the overall maintenance of the front-end codebase for the web application. Integrated tools like Sentry to catch issues happening on production. Later, I added Sentry to the staging server to catch all hard-to-reproduce matters.
  • Added unit test coverage using the React Testing Library. I wrote many tests myself and motivated the team by introducing the code coverage concept and its importance in the sprint retrospectives.
  • Scaled the unit test coverage to almost 90% and added a few end-to-end tests for the main pages of the user journey. Later, integrated the tests into the CI/CD pipelines.
  • Helped the team in migrating the codebase from React to Next.js.
