  • Serverless-offline

    A serverless plugin that emulates AWS API Gateway and Lambda locally. I wrote it in 2016 and have maintained it ever since with more than 180 collaborators. In 2020, It reached a total of 3,500 stars and 250,000 downloads per week and continues to increase. It's the top serverless plugin in terms of users, downloads, and activity.

  • Pix: French Ministry of Education

    An application to test and assert civil servants' and students' information technology skills. As a full-stack developer, I was part of the second wave of developers and enjoyed every bit of developing the app.

  • Gourmet: eat, review, love

    A web application to explore and review restaurants. Any user can register one or more restaurants. Restaurants can then be reviewed by users, and owners can reply. Restaurant owners can access the restaurant's dashboard to read meaningful information about the reviews and analytics for their restaurant. Administrators can update and delete any data on the app.

  • Personal Website

    I built this website to display my skills in vanilla JavaScript, along with a few pieces of my artwork. The site is the hardest app I've developed in terms of code complexity. It includes famous mathematical wonders such as fractals, polyhedrons, and Fourier series.
