I wrote my first program at around 10 years old — a Commodore 64 connected to a TV, learning from my father's programming books in Basic. I stepped up to Turbo Pascal next, building simple games and tools on my own. That self-taught curiosity led to a technical secondary school, then a computer engineering degree with a microelectronics specialisation. 15+ years of professional work later, the stack has changed completely — the approach has not.
