Smart-signage device platform
Tech Lead · Hivis Group
Primary software owner for a $750k proof-of-concept that took a connected smart-signage platform from feasibility into build and field trial, supporting 900 live devices with a path to 20,000.
Challenge
A state transport authority needed to know whether a fleet of connected smart-signage devices could be operated safely and at scale before committing to a full rollout. The hardware, firmware, field operations, and cybersecurity reviews all depended on a software platform that did not yet exist, and a hardware/software mismatch or a cyber delay would have stalled the whole trial.
Approach
As the primary software technical owner I designed the Azure platform architecture, delivery approach, and cybersecurity-aligned controls, then aligned software, firmware, hardware, cyber, and field-operations stakeholders around shared architecture documents, API contracts, deployment processes, and a firmware test and simulation strategy. Real-time, event-driven telemetry replaced fragmented manual checks with structured dashboards, alerts, and maintenance workflows, and a three-year roadmap sequenced migration, authentication, integrations, and predictive maintenance.
Outcome
The project progressed from feasibility into a live build and trial across 900 field devices, with telemetry and fault-modelling spanning device data volumes from 24 daily records up to roughly a million per day. The platform and its ISO 27001-aligned controls were built to scale toward ~20,000 devices and to satisfy the authority's cyber review.
