Amadeus being in the process of migrating its on prem infrastructure to the cloud needed engineers to understand the existing software and infrastructure constraints of the migration process and develop tools and practices to ease the migration for the applicative teams. As part of the OTF team (Open Transaction Framework, backbone of the Amadeus ecosystem).

I was involved with:

• The core interceptor project aimed at monitoring and collecting core dumps in all Amadeus environments (dev, test, staging and production).
  • Production of dashboards as code
  • Definition of alerts for applicative teams
• The Cloud OTF Router, a routing component aimed at routing traffic to the Amadeus back-ends running in Microsoft Azure without the need for upgrading the service discovery system configuration.
  • Dependency update and new release deployment
  • Monitoring and support
• Transition to Argo CD and Helm charts for applicative deployments.
• Development of Python scripts for various automation
• Support for the queuing system team migration to the cloud

Development on a battlefield awareness application used by foot soldiers as part of Atos Digital battle management ecosystem.

I was involved with:

• The migration of functionalities from the legacy project SICS (Windows, monolith) and it's upgrade to latest standards and architecture SICSD (Android, hexagonal architecture).
• The improvement of the development and testing environment on the project. Putting in place end to end automated testing and Behavior Driven Development practices.
• Evolution of the applicative framework to accommodate new testing requirements
• Development on the Back-end software running in an android environment

The SpineNav project aimed at providing hospitals with a more affordable platform for spine surgeries than the existing ROSA solution from Zimmer Biomet Robotics. It consists of a stand equipped with stereoscopic cameras for object tracking (markers on patient anatomy, surgical instruments) for the hardware. And surgery planning and tracking software. Its goal is to help surgeons in the precise implantation of surgical screws and spacers in the patient spine to address various pathologies.

My contributions included:

• Implementation of new features (patient file management, recovery procedures, etc)
• Detail technical documentation (as requested for medical device certification process)
• Bugfix, defect reproduction and characterization on pre-production hardware
• Testing (automated and manual)
• Design proposal and review
• Continuous improvement of the development environment and team practices via tooling, automation script, CI pipeline evolutions

The ROSA ONE platform is used for brain and spine surgeries. It consists of a stand equipped with stereoscopic cameras for object tracking (markers on patient anatomy, surgical instruments) and a robotic arm derived from the manufacturing industry holding surgical instruments. The software is capable of handling surgery planning (surgery preparation phase: load of CT and TEP imaging data and planning of surgical tool insertion trajectories) and live tracking of the surgical instruments (via calibration using imaging data, patient anatomy and trackers) to ensure precise positioning of surgical tools during various types of surgeries. The use of the ROSA platform help decreases recovery time and procedure duration and increase precision while reducing preparation time.

I was involved with:

• Maintenance of the software
• Investigation, reproduction and fix of issues reported on the field
  • Notably heavy investigations and improvements on concurrency issues due to synchronization between the applicative software and the robotic arm state machine.
• Close collaboration with the post market surveillance team to provide risk assessments and technical analysis
• Features development to meet the evolving needs of surgeons with their corresponding impact analysis and technical documentation.

Amadeus provides airlines, travel agencies, hotel chains and car rentals companies with a comprehensive set of software. Most of those components are highly configurable by the customers and many rely on the Logon Security Service (LSS) for access and right management. This custom build platform handles high traffic and relies on multiple layers of caching to ensure low latency in the Amadeus system.

My contributions to this service include:

• Implementation of new features and evolutions on the access right management platform
  • Introduction of new APIs endpoint
  • Evolutions to accommodate hospitality business expansion into smaller businesses since most of the software is geared towards complex configuration of airline access management policies
• Automated test implementation
• New implementations in the underlying C++ library
• Close collaboration with PDA (product definition analyst), QA (quality analyst) and DevOps teams
• Validation of deliveries with DevOps engineers during load process (remote tests on newly updated nodes)
• SQL queries optimization
• Python integration test development

Modeling of the neutronic behaviour of research nuclear reactors using Tripoli (computational code developed by the CEA).

I was involved with:

• Set up of numeric simulation of the neutron flux of research core in different instrument load out configurations
• Development of scripts aimed at simplifying the definition of the core geometry base on instrument emplacement.
