Problem

São Paulo publishes public police report data, but it is raw and fragmented, making street-level safety context hard to understand for the public.

Solution

Aggregated police reports into street-level safety indexes with geospatial processing and an interactive map so anyone can browse incidents per street.

Problem

Planning events with friends was scattered across chats, making it hard to coordinate who is going, what to bring, and how to split costs.

Created a mobile app to create events, track RSVPs, organize responsibilities (who brings what), and split expenses.
