Geofencing Verification

The Infrastructure Challenge

Eliminating remote employee timesheet fraud (e.g. clocking in from home) and providing secure, auditable separation of multi-tenant corporate databases.

The Engineering Flex

We bypassed generic framework options and constructed a modular, optimized algorithm directly tailored to the systems overhead constraints.

We implemented hardware-level geofencing utilizing Expo location tracking to match user coordinates against physical office radius parameters on clock-in. On the backend, we secured the database utilizing PostgreSQL Row-Level Security (RLS) policies inside Supabase, validating that tenant organizations can never access each other's timesheet data.

    SELECT tenant_id

Project Outcomes

100% geofenced verification, eliminating timesheet and location fraud.

Enterprise audit compliance with clean multi-tenant database separation.
