Experienced, close teacher focused on each individual pupil

Hello, I'm Rafa and I have more than 15 years of experience teaching English, German and French and also science (maths, chemistry, physics) both at the class level with 25 students and at the individual level. I do it by vocation because I already have a job as a, IT technical. I have taught both children and adults and I prefer to focus on individual exercises to adapt to the needs of each student since it is difficult to find 2 students with exactly the same knowledge/needs, so when do we start?
