About me

I am a Data Scientist and PhD in Computer Science with four years of experience specializing in statistical analysis, data modeling, machine learning, and data-driven decision-making. My expertise lies in developing innovative data solutions and implementing machine learning models that optimize complex systems and drive operational efficiency and strategic planning.

I have extensive hands-on experience working with large datasets, particularly in areas such as traffic management, environmental impact studies, and urban planning. Proficient in Python, SQL, and machine learning libraries like Scikit-learn, as well as data visualization tools such as Tableau, Power BI, Matplotlib, and Seaborn, I am skilled in transforming raw data into actionable insights that support informed decision-making. My ability to automate data extraction, ETL processes, and data transformation workflows has enhanced operational efficiency and streamlined research and development efforts.

Throughout my PhD research and professional career, I have developed advanced skills in statistical modeling, predictive analytics, and data mining. I excel at communicating complex data insights to both technical and non-technical stakeholders, ensuring that my work adds value across diverse teams and drives impactful business outcomes.

I am passionate about using data to solve real-world problems and thrive in dynamic, cross-functional environments where I can collaborate with others, innovate new approaches, and contribute to an organization's growth through data science and analytics.

Studies

  • Sept. 2021 - Dec. 2024
    PhD in Computer Science
    UNIVERSITAT POLITÈCNICA DE VALÈNCIA

    My PhD focuses on developing an urban traffic management system that integrates pollution criteria to optimize traffic flow and air quality in cities. Throughout my research, I have gained expertise in critically analyzing complex ideas, advanced data analysis, and visualization techniques. This process has also strengthened my skills in communicating and disseminating research findings effectively. I have a comprehensive understanding of my field but also I am equipped with the resilience needed to tackle future challenges.

  • Feb. 2023 - Oct. 2024
    Master in Project Management
    EAE BUSINESS SCHOOL

    During the Master, I studied the necessary skills to manage challenging projects.
    Risk management, finance and team, as well as leadership, are some of the topics covered in the program, which also includes practical experience through a final project. I am also developing my communication and leadership skills, which are essential to successfully manage a project.
    Upon completion, I will have an in-depth knowledge of project management, which will make me an important asset to any organization.

  • Sept. 2020 - July 2021
    M.Eng. in Computer and Network Engineering
    Universitat Politècnica de València

    Throughout the master's degree, I have learned various concepts ranging from software development to computer architecture.
    What I highlight the most from the master are the knowledge learned in relation to IoT, communication networks, Python development and the reading and writing of research papers.

  • Sept. 2018 - July 2019
    Erasmus + in Maribor, Slovenia
    University of Maribor

    During my Erasmus in Maribor, I learned several things: how to integrate in multicultural environments, programming languages among which C++ stands out, how to manage in an environment that is not yours and diverse cultures through the trips I made (Czech Republic, Slovakia, Greece, Austria, Italy, Hungary, Serbia, Bosnia...).
    Without a doubt, I think that Erasmus has been the best experience of my life.

  • Sept. 2016 - July 2020
    B.Eng. in Telecommunications Technologies
    UNIVERSIDAD DE LAS PALMAS DE GRAN CANARIA

    During my years at the University of Las Palmas de Gran Canaria, I have acquired technical and personal knowledge.
    On one hand, from the technical side, there are wide aspects that go from web development to network management. For example, programming languages I have studied are: Java, JavaScript, Python, PHP, C, ASM... Of these I highlight that my greatest knowledge is in Java and Python.
    On the other hand, of the personal ones, the following stand out: teamwork, confidence in one's partner, perseverance, sacrifice and effort.
