About Rubén

I am a Senior Frontend Developer with extensive experience in developing modern web applications, specializing in Angular and building clean, maintainable, and business-oriented interfaces.

I collaborate with companies and teams that need occasional frontend support, development of specific features, resolution of complex bugs, or improvement of performance and code quality in existing projects.

I work with special attention to:
Clear, scalable, and easy-to-maintain code. Frontend best practices and architecture. Usable and consistent interfaces. Seamless integration with backend and product teams.

I am accustomed to joining ongoing projects, quickly understanding the technical context, and providing value from the outset. I have experience working with distributed teams and agile methodologies, easily adapting to different environments and work paces.

I offer flexible availability for small projects, hourly collaborations, or temporary support during peak workloads, always with a practical, results-oriented approach.

Experience

  • Vueling
    Web Developer Vueling
    January 2019 - January 2021 (2 years)
    I was responsible for maintaining and developing new features for the desktop website. It was an MVC in .NET Framework that used Navitaire libraries on the backend, and the layout was done with Razor. In this project, I had to do both front-end and back-end work.
  • UNIR
    Web Development UNIR
    August 2023 - Today (2 years and 10 months)
    I have developed my career in two key stages: initially as a Full-Stack Developer, in charge of integral backoffice projects where I implemented user interfaces with Angular and built backend services in .NET Core.

    My performance allowed me to move up to the Software Architecture area, where I took on a strategic role focused on optimizing the codebase. In this phase, I was responsible for the design and development of internal libraries for massive reuse, as well as the analysis, planning, and execution of migrations of the technological ecosystem to the latest versions of the frameworks in use. This work was fundamental in reducing technical debt, increasing security, and ensuring the scalability of applications.
  • Flylevel
    Web Developer Level
    TRAVEL AND TOURISM
    January 2021 - August 2023 (2 years and 7 months)
    In this project, which was within the Vueling environment, although it was a different airline, I had to perform maintenance and development of new functionalities for the website, which was responsive. In this case, I didn't have to do the layout, but I did have to adapt the layout provided by the designers to the page and add its dynamic functionality. It was a hybrid where one part was MVC with .NET Core and the other part was made with Angular 9. I started by taking charge of backoffice projects where layout was done in Angular and backend development in .NET Core. Then I moved to the architecture area where I was responsible for the development of the company's internal libraries, as well as the analysis, creation, and migration of projects to the latest versions of the libraries and frameworks used.
