I worked (mainly) in network management apps.Projects were challenging since We were building UIs to make easy-to-use features related to the management of anything related to network management and monitoring, such as cyber security, routing, or WANs and LANs management.The UI needed to be up to date with data changing almost per second in most cases.The team used HTML, CSS, and Javascript. VUE was the framework used for building reusable components.We maintained different internal components libraries to reuse components between the different apps.And Web workers were used for keeping real-time data up to date between web clients.We worked in small agile teams. Knowledge-sharing, best practices, state-of-the-art code quality, future-proof features, MVP focus and collaboration with other departments was a priority for the company, which made the work at OmniAccess definitely a challenging but amazing experience.

I was working in "Travel circuits" product. The team was in charge of building new features and maintaining the front-end and the back-end full product flowWe worked from the database to the UI.The tech stack in the front-end side was HTML, CSS and Vanilla Javascript (in some projects).In another projects We used Angular (with Typescript) and SASS.In the back-end side We used Java 8 with Spring boot.

I had the pride of working at Ryanair almost 2 years in a fast paced and international environment.What I am most proud of is having collaborated in the digitalization of some tools that are used every day in Europe's favourite airline to carry out flight operations.During that time, the team I was working with built 5 internal operation apps from scratch using Angular stack.Of course I can't explain any private detail about the purpose of the software We built.But they provided value to business in terms of processes automation, which is key in the current context of the travel and tourism market.From the personal point of view, I had the pleasure of working with high skilled and multidisciplinary teammates.Which makes me firmly believe team work is essential in agile team for providing value (as previously mentioned) to business.We worked following git flow with a code review (through pull requests) for every feature or bug, which improve code quality and teams collaboration.As I said before, Angular was the stack chosen by the company at the Front End side. (Java was at the back-end side but that wasn't my field).It clearly helped allowing teams to grow fast but building well-structured software.Among other front-end tools, I learnt how to work with (or improved knowledge):- HTML- CSS- Typescript- RxJS- NGRX- GraphQL- Functional programmingI learnt how to work with Amazon Web Services (AWS) platform and I cooperated with the team I was part of managing the projects deployments from DEV to PRE-PRODUCTION stages.So I could gain knowledge about DEV Operations (aka DEVOPS) and tools like Docker and NodeJs (for some integrations with 3rd party APIs).

I contributed to various teams during my tenure at eDreams Odigeo, including the “Flight + Hotel” product team. Comprising a Product Owner, UX specialist, QA professional, and five developers (alongside a BA profile coordinating across teams), the collaborative environment was both diverse and dynamic.This experience was exceptionally rewarding, allowing me to engage in the end-to-end process of bringing an idea from design to production. Iterations were seamlessly implemented through A/B tests, Google Analytics analysis, and user sessions facilitated by the team’s UX expertise.Operating in a genuine agile and fast-paced setting, our guiding principle was to “Fail as quickly as possible to learn, and improve the product from experience.”Our tech stack included HTML, CSS, Javascript (utilizing Backbone JS), and Java. Version control was managed through Mercurial and GIT, with Jenkins serving as our Continuous Integration platform.

I worked on the maintenance of a web application, and the new version of it in the pharmaceutical robotics sector.In the front-end part of the application, the technologies used were HTML, CSS, Javascript (using jQuery as the main library for the UI). We also apply Bootstrap 3 as a CSS framework.From the backend point of view, in the new application we work with CodeIgniter (PHP framework), and MySql.Additionally, I worked on an application developed with VB.Net and SQL server.I also made a one-off change to an existing Android app.

Intership in a Microsoft innovation centre focused on Tourism Technologies.I could learn the basics of Microsoft technologies building some apps with C#.Some of the engineers working in this innovation centre were Microsoft MVP, so learning from them was a great opportunity.
