About

Hey there - my name is Greg Hogg, a statistics alumni from the University of Waterloo in Ontario, Canada. I'm an ex-AI researcher who's published medical papers with Deepbreathe.ai, a startup that continues to win awards in the US military due to my and other's research. I still do AI contracts with companies like Nvidia, HP, and other big names today. I'm most known as a popular coding teacher online for interview skills like DSA and System Design, with over 150 million organic views and 650k+ followers in the space. My day job is running MLNOW Inc (which owns Algomap.io), where I help busy individuals get into the world's best software engineering roles at companies like FAANG. My company's website Algomap has over 75,000 users and a personalized live program tailored to cracking FAANG.
