Real systems, with their real status.

Challenge

An ageing toll revenue system, with manual per-department deployments, dependence on lane equipment and no central traceability of operations.

What we did

• Relational analysis and design of the system data
• Source code changes and deployment across 7 departments
• Support for toll and weighing posts, and coordination of satellite connectivity
• Administration of centralised databases and nationwide backups

Status and outcome

• Sustained national operation throughout the period
• Knowledge base later reused for centralised monitoring

Challenge

Each station reported in isolation: there was no national view and no standard integration with lane and weighing peripherals.

What we did

• Development of the tracking and monitoring system
• Deployment across 5 departments
• Integration of weight indicators, traffic lights, barriers and IP cameras

Status and outcome

• Centralised view of stations and weighings
• Integration protocol reused in later proposals

Challenge

Digital affiliates cannot prove which ad produced each sale: attribution is lost between the landing page, the affiliate network and the ad platform report.

What we did

• Multi-tenant architecture with row-level isolation and an append-only ledger
• OIDC identity, opaque click identifier and signed server-to-server postback
• Plan entitlements and usage metering in the core

Status and outcome

• Foundations deployed and verified with cross-tenant isolation tests
• Dashboard, landing editor and public tracker under construction
