team black box

i joined team black box for my first long internship (six months) and rotated through take a sip, i won't forget, and land blocks. each one skewed differently: consumer ui, text intelligence, and geo visualization.

the stack was react native, firebase, and zustand for state. it was my first time designing custom ui from scratch and my first real exposure to skia on mobile.

on take a sip i built the custom sips flow end to end and wired it to firebase. i also added markdown-based changelog support inside the app so shipping notes could stay in-product instead of bouncing people to email or a blog.

for i won't forget i used compromise.cool to pull structured reminder details out of free-form text. tuning the parser moved accuracy up by about 30% against our test set.

i wrote unit tests around the extraction paths so refactors didn't silently break production behavior. that was my first time treating parsing like a subsystem, not a one-off script.

on land blocks i took location data and drew polygons on the map using react-native-skia, wiring geo inputs to something visual on screen.
