Hello dear Sir or Madam! My name is Juan Antonio and I am a Chemical Engineer with an entrepreneurial spirit. My passion is hydrogen as a clean energy source and I am very interested in developing my profession in a creative and innovative environment. For this reason I am applying for jobs where I fit my profile.
My great interest in the renewable energy and energy efficiency sector, together with the affinity of this sector with my skills and training, accredit me as a candidate for professional positions. Without further ado, I would like to thank you for your attention and interest in me, and I would like to take this opportunity to greet you very sincerely.

My professional career is moving in the right direction to make me a person balanced in knowledge and experience. This is my personal goal.
In particular, I strive to continually expand knowledge, improve my practical application skills, and form my own critical opinion.
I am currently specializing in hydrogen, innovation, creativity and entrepreneurship. I finished my degree and master's degree in Chemical Engineering at the University of Granada. I passed the baccalaureate in nature sciences and health and the rest in a public school. Expand information here.
I am always willing to learn new things in subjects related to my profession, preferably from the hand of professionals and companies in the sector. I have a curious attitude towards scientific and engineering subjects. Expand information here.
I am not afraid to make mistakes and learn from my mistakes, each stage of my formation is accompanied by another stage of experience and reflection on what I have learned. I use experience to make judgments and make prudent decisions. Expand information here.
Being able to communicate with people from other countries and in other languages is fundamental for me, that's why I'm always in continuous training. Learning languages helps me to open my mind and make better decisions in my work. Expand information here.
Since 01/09/2019 I have held the position of Technical Project Manager of the Hydrogen Department at Hydrogen Clean Energy where my work focuses on planning engineering projects with a high degree of innovation and creative design. The key phases of my work are: - Process engineering: This is the moment when basic engineering is developed and evaluated. - Scope: At this stage you look closely at the technical teams that will be part of the process. - Necessary documents: All engineering projects must be supported by reference documents. - Basic engineering: a detailed description of the processes. - Distribution plan: the detailed description of limits, accesses, dimensions, etc. - Engineering management: use of all personnel and resource units to carry out and supervise operations.
Desde el 23/10/2018 I held the position of director of the hydrogen department in Letter Ingenieros where my main functions are to implement and develop the technical strategy, as well as to check the correct functioning of the systems to obtain a better final product. In this position I am mainly involved in my capacity for analysis, strategic planning, communication and leadership.
Since 12/01/2016 I have held the position of Director of Operations at the company Sonrisas Musicales where my main functions are to establish the market strategy, ensure the proper development of the activity and manage internal resources. In this position I am mainly involved in strategic planning, communication and leadership.
From 2014 to 2016, I was executive director at Eden Hogar where I and the director of the company created the vision and strategy of the company through the business model, as well as the definition of the work methodology and the motivation of the team.
My pre-professional experience is wide, the last jobs I have had have been in the companies Burger King and Kinépolis where I have worked in teams and have held various positions. In another area of work is my experience as a teacher of private classes for the subjects of mathematics, physics and chemistry.
In my daily work I am very tidy, I like to set goals at the beginning of the day and execute the action plan with discipline. I try to create a productive working environment and be a good teammate.
Success is my main objective, so I strive to have a broad vision of the problems, to have clear what my abilities are and to be constant in my work.
