The most amazing...

...thing I've designed and implemented was an interactive tool for a Fortune 500 company that allowed to visualize real-time 3D air quality data on a map.


  • Founder/Developer

    2018 - PRESENT
    • Developed a Node-based software to create interactive 3D web applications. Current demo (beta):
    • Anticipated end-goal will be to create 3D configurators for online shops as well as online real-time visualizations.
    Technologies: Ruby on Rails (RoR), Ruby, TypeScript, GLSL, WebGL, Three.js, 3D Modeling, Algorithms
  • Senior WebGL Creative Developer

    2020 - 2021
    Virtual Tour Company
    • Acted as the sole WebGL developer and was in charge of creating a virtual tour, where the users can navigate inside a space where many high res 3D models are displayed.
    • Optimized 30+ different 3D models, each being a 1G+ file. Reduced them each to 1Mb without loss of visual quality.
    • Created different level of details (LODs) for each model and switch which version is displayed depending on the camera position.
    • Developed the camera navigation system where the user can click on the point of interest (POI) and this animates the camera to the target position (At each camera position change, hide or show the relevant objects, such as new POI or specific tractors).
    • Developed the look dev, which included the creation of lightmaps, the addition of a sky to create stunning visuals.
    • Created custom GLSL shaders for pulsating POI.
    Technologies: WebGL, Three.js, TypeScript, HTML, CSS, GLSL, Webpack, Houdini, Python, Vex, 3D Modeling, Algorithms
  • Lead Map Visualization Developer

    2020 - 2020
    Health Facility Company (NDA)
    • Created a visualization tool to view medical facilities over the US.
    • Implemented designs provided by the client to allow users to create PPE requests, saving to the database, and displaying summarized previews to visitors.
    • Implemented a custom visualization tool, with a combination of data points displayed on the map and others on an online spreadsheet.
    • Tested several map look and feel, involving map skins (dark, light, colorful) and color scheme for the thousands of markers present at any given time.
    • Optimized loading system to pre-cache map data, update it as users entered new data, and display it in a reasonable time frame.
    Technologies: TypeScript, Vue, Ruby on Rails (RoR), Mapbox, 3D Modeling, Algorithms
  • WebGL Developer

    2018 - 2019
    Fortune 500 Telco (NDA)
    • Created several design propositions to display air quality data in 3D over a map.
    • Implemented tools and technology to create 3D histograms from the real-time feed with three.js and custom GLSL Shaders on top of Mapbox.
    • Fetched street data from Mapbox, converted it to geometries, and applied custom GLSL Shaders to show street animations, mimicking traffic flow.
    • Implemented interactions allowing users to select any streets and display data for that location.
    • Implemented a tool to navigate back and forth in time, allowing to see past air quality data.
    Technologies: Houdini, Vue, Three.js, GLSL, Mapbox, WebGL, Algorithms
  • Lead WebGL Developer

    2018 - 2018
    Streaming music provider (NDA)
    • Created a 3D interactive globe with dots representing music events using Houdini, Three.js, and Vue.
    • Created a system to artistically place music events using Houdini, and export them to Three.js. The goal was to find the right balance between accurate locations and visually pleasing dots distributions.
    • Created custom glsl shaders to have 3D wave effects on the globe when a user would hover over a dot.
    • Given the artistic quality of the project, strong emphasis was put on the look and feel. and the final design is an adaptation from the pdf designs given by the client, as the perception changed once animations were in place.
    • Created the various animations: for the camera, rotation of the earth, wave effects, stars fading in.
    Technologies: Houdini, Vue, WebGL, Three.js, Algorithms
  • Three.js/WebGL/Vue Developer

    2018 - 2018
    • Implemented a site for an event at a music company.
    • The site was an experience centered around a 3D globe, on which 50+ dots were placed at precise locations to announce music events.
    • The user could navigate in time to display specific festivals, as well as interact with the globe, and click on the various dots to display history and statistics of each one.
    • The globe design was created using Three.js instancing system, combined with a custom glsl shader reacting on user click, to create a smooth propagation of color on the globe.
    • I've also used Houdini to pre-generate some geometries, such as the points location and the countries texture.
    • Custom event propagation was used to display and position event label created in html, based on the 3D position of the dots in threejs. Distance from camera also had to be taken into account to make the dots fade away when crossing the horizon.
    Technologies: Chart.js, Vue, JavaScript, GLSL, WebGL, Three.js, Algorithms
