About
I enjoy building projects that solve real-world problems. My projects include a disposable email service (80k+ monthly web users & 26k+ mobile downloads), a gaming analytics platform (8k+ monthly users & $1,200+/month in ad revenue at seasonal peaks), and a price tracking tool for Costco shoppers.
