Hi! I’m Martín, an engineer and AISTS Master’s student in Sport Management & Technology in Lausanne. I teach Math, Sciences, English, and Spanish with a coach’s mindset: clear goals, structured sessions, and steady progress. My background in sport as a coach, referee, event organizer, and performance analyst shaped the way I teach: I break complex topics into simple steps, build confidence fast, and help you perform with ease. What you can expect: Clear explanations + step-by-step methods Plenty of guided practice + correction A simple plan after the first session (strengths, gaps, next steps) Support for school curriculum, exam preparation, and adult learning Lessons available in English or Spanish (and French support at A2).

Want to stop “fighting with data” and start getting answers? In these lessons, you’ll learn Excel and/or Power BI in a practical, results-focused way, the same approach used in real corporate environments to build reports, dashboards, and automated workflows. We’ll start from your current level, build strong fundamentals, and quickly move into high-impact skills: cleaning data, building a solid model, writing DAX measures, and creating dashboards that communicate insights clearly. Bring your own dataset (work, school, sports, personal projects) or I can provide exercises. The goal is simple: you become faster, more confident, and more valuable with data.
