Daniel Venna Kauffmann

I'm a computer scientist with 5 years of experience as a full-stack software engineer.

I've worked in multiple Brazilian companies and one international team. In the past few years, I've shipped full-stack products from scratch — from a solar sales CRM with maps used by hundreds of sellers, to an AI startup backed by an angel investor with hundreds of users searching every day, to leading mobile authentication/2FA for a Brazilian fintech.

Projects

Safety indexes from public police report data

Oct 2025 – Present
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.
