I’m a medical doctor, software engineer and regulatory dude. I’m also the founder of OpenRegulatory.

Through OpenRegulatory, I’ve helped 100+ companies with their medical device compliance. While it’s also my job that we stay profitable, I try to dedicate a lot of my time towards writing free content like our articles and templates. Maybe that will make consulting unnecessary some day? :)
