Hello! I'm Daniel, a software engineer based in Brooklyn. I enjoy building simple products with a deep emphasis on user experience.
In 2015, I founded a small bootstrapped business1 and have grown it to 1.8MM+ users. I also created Relisten.net, a free and open source concert streaming platform.
I spent a decade consulting on projects for a variety of companies2 at every stage, focusing largely on frontend, product, and UX.
These days I'm exploring some new ideas, maintaining some old ones, and seeing far too many concerts.
