Experience
Inverno Framework
https://inverno.ioThe Inverno Framework is the next-generation Java application framework that has been carefully designed to create efficient, cost-effective, and maintainable cloud-native applications. It takes advantage of cutting-edge technologies like the Java module system and reactive programming that make it a perfect choice for modern application development on the Java platform.
It has been built around four main lines:
• Modularity allows to properly separate the various parts of an application into isolated modules.
• Performance has become an essential concern following the cloud transformation.
• Simplicity is what makes an application stable and maintainable.
• Configurability enables applications to adapt to any particular context.
An Inverno application starts fast and can absorb very high throughput by making efficient use of resources, which directly impacts the operational costs of an application running in the cloud.

Microservice Architecture for Airport IT Solutions
https://amadeus.com/en/portfolio.airports.airport-management-solutionsAs part of an architecture team, I participated in the definition of microservice architecture for the development of airport IT solutions, including airport operational database, airport sequence manager, and fixed resource management system, by distributed teams around the world with 100+ developers.
Designed a Java application framework based on Spring that enforces best practices and integrates with DevOps workflows and monitoring tools.
Provided support and training for the teams to work efficiently with Java, build tools and frameworks.

Web Command Page for an Online Booking and Fulfillment Platform
https://amadeus.com/en/portfolio/retail-travel-agencies/selling-platform-connectA web command page for interacting with a GDS using cryptic commands. I led a team of three people to deliver a web-based command page module integrated into an online booking and fulfillment platform used by travel agencies around the world to book flights, cars, hotels, and trains.
The module was highly extensible and allowed us to define custom user-defined commands to enrich the command page experience with widgets.
It received an internal quality award, leading to an innovation contest with more than 50 participants to propose innovative widgets to be integrated into the product.
