Erictech
Summary
Erictech is a Spanish fleet and asset telemetry platform built on Ruptela and Teltonika IoT devices; I worked for its small Brazilian division as the link to the headquarters in Spain. Engagement focused on shipping Quick Command (Flutter mobile app for SMS-based tracker configuration), Go backend improvements to the tracking system, and supporting mass data migration during the system's rollout at a large enterprise client.

Enterprise data migrationThousands of users, devices and vehicles migrated to the new system
Enabled the system's enterprise rollout by supporting mass data migration of thousands of users, devices and vehicles.
