Software developper

Graduated from INSA Rennes engineering school and Université Lyon 2

 

Specialisations:

• 3D graphics
• video games
• geographic information systems

I like software development, video games, and geography, but not only, as I dabble with pretty much anything nerdy I encounter, including but not limited to linguistics, drawing, music theory and history.

 

I have worked on:

• Several commercially released video games at Ankama
  • Including Krosmaster Arena
• Realtime 3D city viewers at Siradel (part of Engie Group)
  • Unity as well as WebGL based
  • For multibillion-revenue companies
• Personal projects

 

And more precisely:

• Unity based game development
  • Base application framework, sits on top of Unity and provides:
  • Dependency injection capabilities
  • Event-command pattern
  • Scene compositing (declare a scene in a simple struct, at runtime the scene is created, abstracting main data vs scene vs asset bundle, automatically loading and unloading data, code and event definitions)
  • Loading transitions
  • In-game scripting
  • Camera system (many modes, transitions between the modes)
  • UI
• Realtime city viewer in Unity
  • Fully dynamic data loading
  • Composable data visualisation
  • Ex.: Scale building heights according to inhabitant count, colour them according to revenue, while displaying a crime heatmap on the ground and colouring roads according to traffic
  • Sparse virtual texturing (aka megatextures) system, including associated texture generation and update tools
  • Multithreading system (task, continuation and executor based)
  • Advanced coroutine manager
  • Dynamic line-on-mesh drawing systems (polygon-based and decal-based)
  • Custom terrain collision system
  • Camera system
  • Runs on PC, tablets and web browsers
• WebGL development
  • Based on the Cesium 3D globe renderer
  • Tiled 3D-building rendering system
  • Level of detail support
  • Dynamic texturing and palette-based colouring
  • Efficient data format
  • Format conversion and texturing tools
• Java server development
  • Highly concurrent architecture (multiple thousands of simultaneously connected players)
  • Binary client-server protocol
  • SQL data storage and retrieval (with and without ORMs)
• Build systems — continuous integration
  • Using Maven as project defintion tool
  • GitLab for continuous build/testing/integration/deployment
• Web stuff
  • Node.JS server development
  • Client-side JS
• Flash game development
  • Some things I used to be quite proud of, but hey, nobody uses Flash anymore!
