About Natasha

I am a Full Stack Developer with over 5 years of experience in web applications, internal administration systems, and scalable enterprise solutions.
My greatest specialization is in frontend development with Vue.js (v2 and v3), complemented by experience in Node.js, PHP, and SQL, applying best practices such as testing (Jest/Vitest), CI/CD, and Gitflow.

I have led the modernization of platforms for public and private organizations, as well as the implementation of solutions with artificial intelligence, data visualization (ECharts), chatbots, and PWAs in sectors such as health, education, professional football, and retail.

I currently reside in Spain with a valid work permit and am part of a development team for a leading retail client.

🚀 I am open to collaborating on additional projects, both freelance and team-based, where I can contribute my experience in modern frontend and full-stack solutions.
If your company or project needs a specific implementation, system migration, or temporary team reinforcement, do not hesitate to contact me.

    - I participated in the re-engineering and migration tasks of the internal administration system for the College of Psychologists, moving the application from Sencha Architect (EXT JS) to Vue 2 for the frontend, which allowed for modernizing the interface and improving user experience. During this process, I implemented frontend solutions using Vue 2 and its ecosystem, ensuring agile and efficient navigation. Additionally, I performed backend tasks using PHP with SLIM Framework and SQL, optimizing database management and server logic to ensure the system's proper functioning. I was also responsible for the continuous maintenance of the platform, resolving incidents and making periodic improvements to ensure its stability, performance, and adaptation to new needs.

    - Following the pandemic, I developed from scratch a scheduling module that interacts between the affiliate portal and the internal administration system. The portal allows affiliates to request appointments, while the internal administration system manages schedules, non-working days, and appointment administration. The portal development was done using HTML, CSS, and Bootstrap, ensuring a user-friendly and accessible interface. On the administration side, I used Vue 2 to create a dynamic and efficient solution for appointment management. Furthermore, I developed the backend with PHP and SQL, enabling the integration of both platforms and ensuring the correct management of information and appointment availability.
    This module significantly contributed to optimizing internal processes and improved user experience during times of social distancing. I performed simple maintenance tasks on the affiliate web portal, developed with HTML, CSS, JavaScript, PHP, and SQL. These tasks included detecting and correcting errors, minor updates, functionality improvements, and database adjustments.
