Senior Full Stack Developer (MERN) specialized in Node.js Backend & IoT with over 5 years of experience. Expert in Clean Architecture, Microservices and cloud optimization (GCP/AWS). Passionate about creating scalable and efficient solutions that solve complex problems.
Developer with over 5 years of experience and an intensive training journey from 2017 to the present, building scalable systems and high-performance architectures.
My career began in 2017 with a solid foundation in web development through the State Professional Certification in Web Development. Since then, I have maintained a constant commitment to technical excellence through specialized training at the best academies and platforms.
I have completed intensive programs at GeeksHubs Academy, Fictizia with 500 specialized hours (325h MEAN Stack Full Stack and 175h MongoDB and Atlas Administrator), and CFTIC Community of Madrid. My training was expanded with specialized bootcamps at Imagina Formación, Escalab Formación and CodigoFacilito, building a solid foundation in full stack development.
Development with AI technologies, MCP (Model Context Protocol) and agent customization. I master APIs and tools with GPT, Claude, Gemini, Mistral, Grok, DeepSeek, MiniMax and ChatGLM models.
I turn complex problems into simple and efficient solutions. Specialization in integrating IoT hardware with high-performance web applications.
Clean code, clear documentation and scalable architectures. Every project applies best practices to ensure long-term maintenance.
Continuous learning with the latest technologies. Solutions that meet current requirements and adapt to future needs.
