Work experience
- October 2022 – March 2023: Part-time Fullstack Developer @ Rotate (Utrecht, The Netherlands)
- Development from scratch of the new web application for analysis of air cargo capacities and revenues for airlines.
- Active participation in the design process, providing suggestions on UI decisions, and testing different frameworks and libraries to choose the one to use.
- Angular App with Fuse for user interface, and NestJS for an API used both by the frontend and customers of the company.
- Application deployed using Amazon Web Services: Amplify with Cognito for user management.
- Data integration with Databricks through headless BI tool CubeJS, and chart creation with Apache Echarts.
- September 2021 – August 2022: Full-time Junior Java Developer @ Ayesa Advanced Technologies (Sevilla, Spain)
- Maintenance and development of enterprise applications for the Andalusian Statistics and Cartography Institute and Culture and Historic Conservation Agency.
- Worked in different teams of various sizes (2-7 people) in a Scrum environment. Multidisciplinar teams with analysts, architects, and developers.
- Position and responsibilities: Fullstack Java web development using Spring Framework and JSP with Thymeleaf or Angular. Development of new features, testing, updating documentation, and deliverables.
- Also worked on improving the quality of the different projects through refactoring and bug fixing. Around 30\% of the code had to be fixed or redone, and multiple vital functionalities had to be developed. Successfully delivered numerous versions to the clients, all met with satisfaction on their end.
- September 2018 – June 2019: Student Research Assistant @ University of Seville (Sevilla, Spain)
- Research into API Documentations to classify dependencies between parameters for a paper by a PhD student. This experience eventually lead to my bachelor thesis in the subject, implementing automatic code generation for APIs considering these dependencies.
