I’m the founder of FightKit — the best app for managing a martial arts school, built by instructors.

I wrote the jQuery Credit Card Validator, which has over 1,000 stars and 200 forks on GitHub. I’m currently working on its modern replacement.

I’m a black belt and an officially certified instructor for the Krav Maga Uri Refaeli organisation. Get in touch if you’re interested in private Krav Maga classes in north-west London.
