What I do

I build the backends and the storefronts and the glue in between. Product engineering that sounds like writing, writing that leaves room for the product.

Day-to-day it looks like TypeScript, Postgres, a lot of Stripe, and a distrust of heavy frameworks. Weekends it looks like mixing desks, custom DAC filters, and arguments about speaker placement.

If one of the brands above is the right door, open it — MadCoolSocial is the widest door, anyone-with-a-business friendly. If you want to work together on something else, the contact link below is live.
