  • Roots of Me

    Created an Electron based desktop app for making genograms. It is written in TypeScript using Electron, and has a Ruby on Rails back end and api. I am the founder of this company and the main developer. I architected and developed the app, and developed an API for it. It is an SaaS app using a subscription model. The main goal is to enable health professionals to create complete, beautiful, and inclusive genograms.

    It consists of:

    • An electron based desktop application
    • REST APIs
    • A dashboard for subscription management
    • A complete training environment

  • Commercial Website for a Broadcasting Company

    Developed a React application with a Node.js back end. The app served high-density traffic. It is the commercial website of one of the top five broadcasters in the Netherlands, containing fragments and teasers as well as programming from the linear TV channels. My role was Scrum Master and Full-stack developer.

    • I helped migrate an existing codebase from Angular to React and built a Node.js API.

    • I managed and developed an internal JavaScript tooling library used by many departments inside the organization. We hosted this using semantic versioning.

    • I helped architect and implement a complete CI system based on Jenkins and Git to bring the code changes into staging and production.

  • Online Learning and Visual Feedback Application

    Developed a Ruby on Rails based visual feedback application. I had the role of full-stack developer, as well as serving as technical advisor to the CEO. This application served many courses and is used by universities and private instructors alike. It is a linear learning platform, but also includes an elaborate visual feedback tool for instructors to provide students with usable and concrete feedback on their creations.

    • I developed many new features for this application.

    • I improved performance for peak hours, when a big group of students would follow a course and submit their work all at once.

    • I upgraded the codebase from HTML and Angular to React in one month in a major rewrite.
