About Mario

Hello world, I am a Full Stack developer with more than 8 years of experience creating digital solutions and more than 3 years training new programmers. Since 2022 I have been part of the eldiario.es team as a developer, where I participate in the design and evolution of high-impact digital products.

My experience ranges from the development of native Android mobile applications to the construction of robust APIs with Node.js and Express, through the integration of modern Frontends with RESTful services.

In the web field, I work in both Frontend and Backend, which allows me to approach projects holistically: from strategic definition and requirements analysis to the delivery of scalable and maintainable platforms.

In recent years, I have also specialized in creating chatbots with Artificial Intelligence, helping companies automate processes, improve customer service, and offer more personalized experiences.

I have had the opportunity to collaborate with startups, SMEs, and multinationals such as Carrefour, as well as founding and managing my own business project, coordinating a development team with which we deliver large-scale solutions.

If you are looking for a technological partner capable of transforming your ideas into solid, innovative, and scalable digital products, I will be happy to help you make them a reality.

Do not hesitate to contact me, even if it's just to chat!
