About
I am a Mechanical Engineer specialized in the calculation, design, and documentation of pressure vessels and piping systems according to ASME, EN, PD 5500, and AD 2000 codes.
I have over 15 years of engineering experience, with a continuous focus on pressure equipment, including:
Pressure vessel design and calculation (PV Elite, manual calculations).
Piping design and compliance (ASME B31.3, EN 13480).
CE Marking and complete PED 2014/68/EU documentation.
Working with gases such as oxygen, steam, compressed air, nitrogen, and flammable gases.
Coordination with Notified Bodies (dimensional inspections, pressure testing, technical file reviews).
I combine my freelance work in pressure vessels and piping design with my current role in an industrial company, where I manage projects, perform legalization processes, and carry out on-site inspections.
What I offer:
✔️ Pressure Vessel Calculations (ASME VIII Div.1 & 2, EN 13445, PD 5500)
✔️ Piping Calculations (ASME B31.3, EN 13480)
✔️ Technical Files for CE Marking (PED 2014/68/EU)
✔️ Detailed Manufacturing Drawings
✔️ Engineering Reports and Dimension Control
✔️ Communication with Notified Bodies
Software:
PV Elite, SolidWorks, AutoCAD, AutoCAD Plant 3D
I deliver accurate, high-quality, code-compliant engineering solutions.

Spain
Throughout my career, I have held various engineering roles that have significantly broadened my skill set and problem-solving capabilities. I have worked in energy auditing, process improvement, technical education, and project management in mechanical, hydraulic, pneumatic, and electrical systems. I have also provided engineering consulting services as a freelancer, optimizing manufacturing processes, reducing energy costs, and enhancing productivity in industrial plants. In my early years, I worked in a boilermaking shop doing pressure vessel projects, so I started developing these types of projects on my own and then moved on to process piping as well.
My experience includes collaborating directly with customers, leading multidisciplinary teams, supporting technical tenders, and working on international projects. These complementary positions have allowed me to develop a strategic vision, solid negotiation skills, and a high capacity for technical adaptation, which I now bring to specialized projects like pressure vessel design and mechanical engineering.
Education
-
ETSII UNED, Spain
Mechanical Industrial Engineer, Engineering, Mechanical Industrial Engineer (6 courses)
1998 – 2006
Activities and Societies:
Registered engineer from the College of Industrial Engineers of Bizkaia No. 6026
My degree is taught remotely. We only had tutoring sessions for a few subjects, mainly for the first two years. Lab practices were done in Madrid. The tutors only answered questions, not explanations. The professors at the headquarters (Madrid) also only answered questions.
It corresponded to the old curriculum. Today, engineering doesn't have as many courses. It's a European-recognized Master's degree, with full competencies throughout Spain to practice in all fields of industrial engineering, not just the mechanical branch. For example, I'm qualified to carry out electrical projects. The dropout rate for this degree when I graduated was tremendous. When I graduated, I was working full-time, but there were years when I had shift work and made better use of my time.

Phisics and mathematics advanced by my own
In my free time, I dedicate myself to studying physics and mathematics independently. As a result of this attempt to learn more about these two fantastic tools, I have discovered a mathematical theorem that I have published. Furthermore, I have advanced studies in relativity that have allowed me to see for myself that some advances in physics in the field of time machines may not be very lucid. Although the theorem is developed in English, the work done on time dilation to demonstrate that conducting physical experiments in these fields is not profitable is in Spanish.
Si alguien está interesado le puedo enviar tanto el enlace al teorema como a los dos estudios de dilatación temporal que demuestran que la ingeniería necesaria junto con la inversión no sirven para nada en este campo y se supone que en millones de años,incluso en una civilización 5+ (estamos en una civilización 0,73 según la escala de Kardashev).
