H.urna

Our goal is to: “awaken joy in creative expression and knowledge”

(Albert Einstein)

H.urna is building a place where people can learn, teach and communicate visually about science.

The purpose of H.urna is to deliver science insights to everyone. It aims a wide range of fields such as informatics, mathematics, physics, electronics etc. Basically, anywhere there is code, equations or symbols that need understanding.

The main idea is that everyone can learn anything and that everything may be learnt. Visualization leverages the human visual system to augment human intellect: we can use it to better understand abstract processes and discover many other things.

As a freelance I made occasional improvements and audits few years ago before being hired to work back on the project leaved out by previous IT services compagnies.

Alongside improvements, debugging and feature redefinitions, my work has included:

Auditing the current plateform from back to front, proposing and improving the architecture

Implementing a Git WorkFlow

Implementing a Coding Style / Best Practices development / Code Quality tools

Implementing a Wiki/Documentations website for developpers

Handling project management tools with remote coworkers

A consequent refactoring of the back-end on both the general architecture and code logic have been processed in an iterative way. Several important optimizations have been made both resulting in a way better user experience, stable plateform, simplified development/deployment process, simplified and reduced code.

I also have the occasion to play with WebSockets as well as WebRTC by developing features such as dynamic message boxes, chat rooms, audio/video calls...

Working in the DxO Framework team developing the core DxO libraries used by the other DxO application's teams. C++ and cross-platform development, I implement new image processing features and enhance code quality, testing procedures and architecture of the current framework. Its main goal is to provide a unified and cross-platform access to the base image correction algorithms along with many utility classes for dealing with Images, Exif, Color Spaces, Collections, threading...
