Since April 2020

Technical manager at CS GROUP - France

Development of the remote sensing library Orfeo Toolbox.

July 2015 - March 2020

Software Engineer at Thales Services SAS


Development of simulation tools for the MicroCarb project

Setting up of a protocol for the generation of simulation images for the MicroCarb project. Development of tools (Python) to easily run the simulations on the CNES' calculation cluster.


Technical support for the Image Quality service at CNES

The Image Quality as CNES develops multiples algorithms to assess the FTM of satellite images. Creation of a GUI (Qt PyQt) for those algorithms. Setting up of virtual machine to make the tools easy to use on various environments. Creating tests to assess the impact of vibration on a test bench.Generation of images simulations for the validation of the Darwin-CU chain. Technical support for the atmospheric correction of Sentinel-2 products In the framework of a competition organized by the NASA and the l'ESA, the CNES uses it's atmospheric correction and cloud detection algorithm MAJA over big volume of data. Development of tools for the preparation of the input data, launching the processing on the HPC, and the delivery of the output data. Python development using linux and Pycharm. Running the processing on a HPC using PBS. Configuration management with Git et Gitlab. Development of a proof of concept using images localization Industrialization of LibGeo, a C++ library for satellite images localization. This library allows one to compute the localization (latitude/longitude) of a pixel according to it's position in the image, and inversely. Use of this library for a proof of concept for the generation of DEM from a couple of images.


Mission at IRT Saint-Exupéry

Work on Deep Learning applyed to satellite image analyse (target detection, classification, change detection). Use of active learning techniques to compensate the lack of training data. Development of an active learning application allowing the training of deep neural networks over the cloud, and the labeling of wisely selected samples by presenting them to an operator to increase the training set. Python development using linux and Pycharm. Use of the Tensorflow and Keras library. Processing distributed on the Google Cloud Platform. Configuration management with Git and Phabricator. Study: Large Scale Object Based Image Analysis Scaling object oriented, segmentation algorithms base on adjacency graph. Use of the C++ library Orfeo ToolBox. Processes distributed on a HPC, with synchronisation between the nodes using MPI. This work is available on GitHub.


**Design and development of a calibration workshop.

Implementation using Python of various approaches for in-flight satellite calibration. Principal library used: Numpy, Pandas et GDAL. DevOps. Configuration management with Git, Gitlab and RedMine.


Development of an application for satellite image processing used in image quality centers

Image processing algorithms implementation (for image quality assessment). setting up of an orchestrator for on-ground processing. Development of an on-bord configuration files manager.

Python development using linux and Pycharm. Use of the SAG framwork (Structure d’Accueil Générique) with Isatis-ng. Use of the GDAL, Numpy, MatPlotLib and gnuPlot libraries. Use of the Phoebus-Lite orchestrator. Configuration management with SVN, Jira and Maven.
