Spanish Engineer willing to help with both scientific subjects and Spanish to children all ages up to high school

I have a bachelors degree in Biomedical Engineering and a Masters on Medical Device Design and Entrepreneurship from Imperial College. I have been helping my friends out with multiple subjects since high school and they have always agreed I have a special ability to understand their different needs and adapt my explanations accordingly. Apart from feeling comfortable teaching all scientific subject, I would also be able to tutor or do "conversation hours" in Spanish.
