I am a freelancer scientific visualization software developer based in Marseille (FR), specialized in GPU and HPC computing. I also design and build clean, interactive, and functional graphical user interfaces which comply with the latest standards.

My working interests range on astronomical, physics and medical computational sciences. One of my previous main software development projects is SlicerAstro.

Davide came highly recommended to us by one of the primary 3DSlicer contributors, and did not disappoint. His expert knowledge of 3DSlicer and VTK was invaluable to our project and both his code and work ethic were of a high standard. It was a pleasure working with him and we hope to again in future.

Davide did a PhD project on 3D Visualisation of Radio Astronomical Data with me. I have been very impressed with the results and especially with Davide's capabilities to provide excellent, user friendly and innovative software. The experience he built up during this project is impressive, ranging from coding software at various levels, including the core level of the well developed package 3DSlicer, to being able to translate user input effectively into well developed and efficient software for the user. The package he developed, SlicerAstro, is now being used more and more widely by the radio astronomical community.

Professional Freelancer

Scientific Software and Visualization developer:
C++, Python, Qt, VTK, Paraview, 3DSlicer, SlicerAstro, parallel computing.

Apr/2017 - Aug/2018

Scientific Software and Visualization Developer

Kapteyn Astronomical Institute, University of Groningen.
SlicerAstro development: implementation of various modules in SlicerAstro and contributions to the 3DSlicer source code to offer visual analytics techniques (algorithms and user/software interactions) for a faster and deeper interaction with the complex 3D astronomical data.

Apr/2016 - May/2016

Visiting Scholar: Kitware Inc.

A scholar visit for developing several customization features in 3DSlicer required by SlicerAstro and other extensions. For example, features such as support for managing custom Slicer orientations presets and GPU based volumetric filters have been implementated with the help of kitware's experts.
The visit was hosted by J.C. Fillion Robin.

Apr/2013 - Apr/2017

PhD Astronomy

Kapteyn Astronomical Institute, University of Groningen.
3D Visualization and Analysis of HI in and around galaxies.
During my PhD, I worked mainly on SlicerAstro, an astronomy (HI) C++ extension for 3DSlicer. Specifically, I have led all the developing phases of SlicerAstro: i) review the visualization prerequisites by understanding deep down the astronomical data and the required tools to visualize and analyze the data; ii) design the software solution and define a roadmap; iii) build the solution using the software developing agile principle.
The thesis is available at the following link.
Supervisor: prof. dr. J.M. (Thijs) van der Hulst.

Strategy Solutions

For creating new scientific software, it is mandatory to deeply understand the challenges of the projects (Big Data, complexity of the data, methodology, etc.) and defining the development requirements.

Software Architecture Consueling

The design of the overall architecture of the scientific package is the first step.

Scientific Software Development

Scientific exploration is highly enhanced by the employment of new techniques: interactive visualization, visual analytics and HPC infrastructures.

Graphical Interface Design

The Qt user graphical interface design is implemented using an AGILE approach taking care of your needs.

Easy To Setup

Togheter with binaries, the software package will be delivered with easy-installation cross-platform compiliation tools.

Clean Code

Clean code which comply to the latest standard is guaranteed.
