    January 2024 - Today (2 years and 7 months)
    Valencia, Spain
    As a manager of a software agency, my responsibilities go beyond technical development. I have led software development projects from start to finish, organizing and coordinating multidisciplinary teams to ensure compliance with deadlines and the quality of the final product. My ability to organize myself and manage multiple tasks and priorities has been fundamental in ensuring the timely delivery of functionalities and client satisfaction.

    In this role, I have worked directly with clients to understand their needs, translating their requirements into clear and effective technical solutions. I have proactively managed client communication, setting clear expectations, presenting detailed proposals and budgets, and ensuring client satisfaction by delivering products that not only meet but exceed their expectations. My client-centric approach has allowed me to build strong and lasting relationships based on trust and transparency.

    In addition to technical and project management responsibilities, I have played a key role in creating and executing growth strategies for the agency. This includes identifying new market opportunities, expanding the client portfolio, and developing long-term business relationships. I have worked closely with sales and marketing teams to develop value propositions and effective presentation strategies, which have allowed us to win new business and expand our market presence.

    As part of my management role, I have also been responsible for resource planning and task allocation, ensuring that projects are completed on time and within budget. I have developed and implemented risk mitigation strategies to minimize impacts on project timelines and quality.

    March 2023 - Today (3 years and 4 months)
    Valencia, Spain
    As a Full Stack developer specializing in the MERN Stack (MongoDB, Express.js, React, Node.js), I have developed and maintained complete web applications, ensuring seamless integration between the front-end and back-end. My experience includes implementing data storage and retrieval solutions using MongoDB, creating efficient data models, and optimizing queries to improve application performance. I have developed RESTful APIs with Express.js and Node.js, facilitating communication between the front-end and back-end, and ensuring data integrity and security through authentication and authorization mechanisms.

    Additionally, I have created dynamic and responsive user interfaces with React.js, using advanced techniques such as Redux for state management and class and functional components to improve modularity and code reusability. I have also worked on optimizing application performance, implementing improvements such as lazy loading, file minimization, and the use of technologies like Server-Side Rendering (SSR) to enhance the user experience.

    I have led development projects, organizing and coordinating multidisciplinary teams to ensure compliance with deadlines and the quality of the final product. My ability to organize myself has allowed me to effectively manage multiple tasks and priorities, ensuring the timely delivery of functionalities. I have collaborated closely with design and product teams to translate business requirements into effective technical solutions, participating in all phases of the software development lifecycle, from planning and design to implementation and deployment.

    Furthermore, I have performed unit and integration tests to ensure software quality, and configured continuous integration and continuous deployment pipelines.
