About Nuria

Hello, I'm Nuria, a fullstack developer with over 10 years of experience, specializing in web and mobile development. I have worked for universities, tech startups, and large consultancies like NTT Data.

📌 Frontend
My strength lies in development with Angular (6 to 16), Vue, React, and Ionic, creating robust and well-optimized SPA and hybrid mobile applications. I use libraries like PrimeNG, Angular Material, Chart.js, or RXJS. I have also worked with Vite and Astro on personal projects focused on performance and SEO.

📌 Backend and APIs
I work with Node.js, Express, Sequelize, and have developed secure and versioned REST APIs. Experience with MySQL, PostgreSQL, MariaDB, and MongoDB databases, as well as managing roles, permissions, and complex business logic.

📌 DevOps and Methodologies
I use tools like Docker, GitLab CI/CD, GitHub, Jira, and workflows like Gitflow. Experience in containerized environments, automated deployments, and Kubernetes-managed environments.

📌 Automation and No-Code / AI
In personal projects, I have worked with WordPress, no-code platforms like Make (Integromat) and n8n, and integrated AI solutions into workflows for tasks such as content generation, customer support, or process control.

📌 Other Technologies
I have developed with Python, Flask, Laravel, GoLang, and embedded software for devices like Raspberry Pi.

✨ I get 100% involved in every project, offering practical solutions, a global technical vision, and rapid adaptation to any team or technology.

Looking for someone resourceful, versatile, and with a growth mindset? I'm ready to boost your next development 🚀
