I’m currently a software engineer at Block. I currently work on Cash App’s marketing engineering team, and have also worked on Square’s (user) authentication team.

Before all that, I did my undergrad at Northeastern University and got my BS in computer science. During that time, I did some research focusing on mobile privacy (specifically, media exfiltration from apps) and interned at a couple of swell startups.
