Chemical Engineer graduated from the Universidad Politécnica de Madrid and specialized in Energy and Environment, the École Centrale de Nantes (France) and with over 10 years of experience in the energetic and technological sector, having developed my career in France, Spain and Belgium. I have a deep knowledge of the entire value chain of waste management and treatment and the different types of waste to energy technologies such us Pyrolysis, Gasification and Anaerobic Digestion. I am used to working directly both with customers and suppliers. I develop my skills with computational engineering software as Aspen Plus, Hysys and costumer model. I also have some experience in the field of data processing too with python, matlab and sql.

$55 total earnings

I am a data scientist with domain knowledge in energy, mechanical, and aerospace engineering, with a PhD in the latter field. I have 7 years of experience in developing Python-based solutions to engineering problems encompassing various topics such as processing of simulation results, time-series analysis, or material property calculations. Most recently I work on problems of mobility and connected vehicles/internet-of-things, leveraging SQL for processing the vast amounts of data generated by vehicle fleets, and Python to find insights and model relevant processes.
