More about me

Dedication, passion and coffee keeps me going

Since the beginning of my career as a programmer I have always enjoyed helping and collaborating with other developers. This has allowed me to meet people from all over the world and learn new things every day of my life.

My student days

I have always liked computer science in general, but the world of development led me to explore new knowledge and goals to overcome, this led me to study systems analysis and application development.

My specialisations

In 2017 I had a turning point in my career, which led me to make different decisions towards a future more focused on my tastes. It was then that I made the decision to complete the master's degree in cybersecurity in Madrid and the MERN STACK development master's degree in Harvard University remotely.

My work experience

I have worked and continue to work for companies in different sectors, this has given me the opportunity to get to know and participate in different departments, facilitating my learning and knowledge in the areas of accounting, customer management, technological advancement, human resources, digital marketing and development.
