High‑volume metro operations platform: real‑time control & intelligence

Executive summary

A major metropolitan transit operator entrusted Babini Mazzari with replacing its fragmented tool‑set with a unified, real‑time operations platform. Handling more than 100.000 daily passengers, the network needed instant visibility at every gate, consolidated analytics across payment and journey data, and security strong enough to satisfy upcoming ISO and GDPR audits. Over three agile sprints we modernised the stack end‑to‑end — introducing live gate orchestration, a modular suite of operational‑intelligence reports, TOTP‑based two‑factor authentication, and a serverless import engine that reduced data‑onboarding from hours to minutes. Within weeks of go‑live the operator recorded a 98% drop in unauthorised login attempts and, more importantly, gained a single pane of glass for day‑to‑day decisions.

Business context

Urban mobility lives and dies by timing. Station staff were toggling gate directions manually while juggling siloed CSV exports for passengers, EMV payments, and vehicle trips. Nightly batch jobs meant yesterday’s data informed tomorrow’s plan. Meanwhile, an ageing Firebase auth layer was a soft target for credential‑stuffing bots. The organisation needed immediate control, fresh insights, and audit‑ready security — without halting service.

Our approach

The engagement unfolded in three tightly‑scoped sprints, each anchored to a concrete pain‑point identified by the operator’s control‑room team.

  • Sprint 1 – Real‑time station control

    We inserted a WebSocket broker that streams every gate’s telemetry — open/closed state, direction, sensor readings and GPS position — into a React/Redux dashboard. Operators can now schedule directional switches in advance, eliminating last‑minute manual toggles during the morning rush.

  • Sprint 2 – Unified operational intelligence

    Four previously isolated data domains — passenger journeys, corporate credit purchases, EMV tap‑to‑pay transactions, and vehicle trips — were funnelled into a single PostgreSQL lake. Micro‑services expose REST APIs, while React front‑ends visualise heat maps, payment success rates and benefit utilisation.

  • Sprint 3 – Security uplift and rapid data onboarding

    We upgraded Firebase to the latest SDK and wrapped it with TOTP‑based MFA, immediately reducing automated attacks by 98%. At the same time we replaced ad‑hoc import scripts with an Azure Functions pipeline that validates, normalises and processes CSV batches of up to 50.000 rows in minutes.

Outcomes

Six months after the final sprint, the control room runs very differently.

Continuous situational awareness

Gate states, sensor health and directional scheduling now update instantly, freeing staff from radio calls and spreadsheets.

Decisions powered by current data

Passenger counts, transaction metrics and vehicle telemetry populate dashboards within minutes, allowing planners to finalise staffing before the last train reaches the depot.

Measurable security gains

TOTP‑protected MFA slashed credential‑stuffing noise by 98% and eased the burden on the SOC.

Rapid data onboarding — and a new revenue stream

Bulk imports process in minutes instead of hours; the same tooling is now offered to peer networks, offsetting additional cloud spend.
