  • React Administration UI and JS Show Runner for Online Theatrical Experiences

    AnyOneThing creates online theatrical experiences which often get the viewer to participate in the play through his microphone and/or camera. I was given the task to create an administrative UI with React which interfaces the backend API (written in Ruby on Rails) and facilitates administrators to edit the sequences of scenes and theatrical cues (videos, audios, images, and sounds).

    Moreover, I created a box office application (also in React) and have optimized and evolved the showrunner to work across browsers and offer a better overall experience.

  • ClassRoomQ | Node.js and React App

    ClassRoomQ is a Node.js and React app that allows students and teachers in virtual classrooms to interact with each other in a structured way. There were two authorization levels. The authentication had to be done through a middleware that could identify the users who were already logged in to a WordPress application. The Node.js and React interaction was done through WebSockets rather than an API to facilitate the 2-way interaction between authenticated and anonymous users.

  • Tradunity

    I was part of a 2-founder team of Tradunity: a bootstrapped startup. Our goal was to help beginner traders find success in the financial markets.

    I was responsible for technical development and leading the technical team as we grew. I also created the original app and integrated it with all the vital services we needed to create a thriving community.

    As our team grew to eight people, so did my responsibilities. We created and executed a very efficient product and promotion strategy, which led to great results. Tradunity has turned a profit from the first month up until the beginning of 2020. The project was closed at the beginning of 2020.
