*OCCASIONAL PROJECTS -Design 3D parts and metal structures. - 3D fabrication and end-use products in our facilities. - Traditional manufacturing process for metal parts. - Use of laser cutter to produce methacrylate components. - Use of Solid Works and CATIA V5.

Diagnostic of mechanical and electrical/electronic failures. - Use of computer diagnosis tools to update, program and manage Electronics Control Units (engine, exhaust emissions, power control, helmet stations), including programming automation. - Calculate and install small isolated renewable energy systems, such solar panels, regulators, inverters, batteries and small wind turbines. - Day-to-day contact with clients, most of them from UK, Germany, France and Scandinavian countries.

Management of the City Light System. - Tele-management of the electrical distribution boards. - Designing new electrical networks, creating lighting studies, as well as adjusting the power network to the new LED system. - Failures management and corrective and preventive maintenance. - Installing remote system devices to automate the switching timing of the lights per day.

- Junior Java Programmer for different management apps. - Data analysis. - Developing a new automatic system to manage the office workflow.

- Working in the manufacturing department as a member of the research team. - Developing a system to detect the snoring sounds using algorithms (signal analysis). - The research was part of my master degree. The algorithm and system we designed was able to detect the snoring sounds from different samples, with a 97% success. - The method was presented to the Spanish Patent Office.

-Creating, designing and testing different ways to “burn/cut” samples of aeronautical composite materials to improve the cutting performance as well as the surface properties after cutting/burning. - Modifying parameters of the laser cutter such as cutting speed, cutting/burning patch, energy per second, laser focus. - Analysing the test results using microscopy and high resolution cameras, re-designing the experiment to improve the results.
