About Javier

Engineer with experience in cloud, critical systems, and IoT, specializing in designing robust and scalable solutions for real production environments. I have worked in demanding sectors such as energy and infrastructure, where reliability and security are not optional.

I have a strong maker profile: I like to build, experiment, and understand end-to-end systems, from electronics and devices to cloud platforms. I regularly work with Python, distributed architectures, industrial communications, and cloud services on Azure and AWS.

In addition, I have a clear business orientation. I am interested in finance, marketing, and product development, so I always look for solutions that are not only technically correct, but also useful, sustainable, and aligned with the project's objectives.

I am very involved in projects, I communicate clearly, and I like to work closely with clients and teams to turn ideas into real and maintainable solutions.
