Software engineer · mobile, web & the bits in between

Hi, I'm Angel.

I build apps that people use every day. Twik, a voice keyboard I built end to end (native Android and iOS apps plus the backend), passed half a million signups in its first ten weeks. At Reelax I'm the primary mobile and frontend engineer across six production apps.
