👋 Hi, I'm Phil!
Critical Power & Mission-Critical Operations Engineer · 12+ years
This portfolio documents systems I've designed, deployed, and operated — from Abuja's citywide traffic control room to estate-scale embedded power-management products.
Open to roles in critical power, embedded systems, and intelligent infrastructure — remote, on-site, or relocation.
About Me
Critical Power & Mission-Critical Operations Engineer || COREN R56955 || NSE 50295 || Embedded Hardware Specialist
I build critical electrical infrastructure that stays running — at city, factory, estate, and product scale. Across 12+ years with the Transportation Secretariat of the Federal Capital Territory Administration (FCTA), CyberFlux, KEGA, and Urban Motion, I've developed the operational discipline behind high-availability systems: layered power redundancy, predictive maintenance, embedded power monitoring, board-level hardware troubleshooting, and direct OEM coordination with Cummins and Studer Innotec. B.Eng. Electrical & Electronics Engineering, University of Ilorin.
I co-designed and operate the Abuja Integrated Intelligent Transportation Information System (AIITIS) — a continuously-operated traffic platform spanning 100+ signalized intersections — and design embedded power-management products for estate-scale energy systems. Hands-on with UPS/ATS, Cummins PowerCommand (Modbus RTU), IEC 62053-21 metering, solar/battery hybrid backup, and BMS/EPMS/SCADA supervision; I cut MTTR from 48h to under 8h at >99% availability.

Selected Work
Selected work across critical infrastructure operations and embedded systems
AIITIS — Abuja Integrated Intelligent Transportation Information System
What it is. AIITIS is the FCT's integrated platform for traffic management and transport administration. Its public face, at aiitis.fcta.gov.ng, handles operator licensing, payments, and vehicle verification for passenger, parking, and goods-transport providers — the layer any visitor can see. Behind it sits the operational core I co-designed and run.
My role. I operate the continuously-staffed control room overseeing 100+ signalized intersections and distributed field infrastructure across the Federal Capital Territory, and lead a cross-functional team of 8 across maintenance, upgrades, and new installations — guaranteed power switching across UPS / ATS, generator, and solar sources, alarm triage, and shift-based operational continuity.
Outcomes. Established the preventive-maintenance and rapid field-swap protocols that cut MTTR from 48h to under 8h while sustaining >99% availability; solar/battery backup at critical sites reduced grid-outage downtime by ~40%. The platform is integrated with Galaxy Backbone for data protection and backup per government standard.
Stack: UPS/ATS architectures, Cummins PowerCommand via Modbus RTU, IEC 62053-21 metering, solar/battery hybrid backup, SCADA-style supervision, automated event logging.
Indigenous Wireless Traffic Light Controller (2017–2025)
The problem. The FCT's signalized intersections relied on imported controllers with hard-coded wireless configurations — prone to RF interference and impossible to reconfigure after installation, so every fault meant another import cycle.
My role. As lead R&D and design engineer on Urban Motion Nigeria Ltd.'s wireless traffic controller project, I took the FCT's first indigenous wireless traffic light controller from research through to a productized device: the QT-TSLC v1.1, a dual-band RF (433 MHz + 2.4 GHz) and Wi-Fi controller branded Quadrum Technologies, with flexible pre- and post-installation configuration, remote access, and a wide 9–36 V DC input. It is operated through the monitoring portal at traffic-signal.quadrumtechnologies.com.
The deployment arc. Initial Abuja deployment in 2017, extended to Kebbi State (2022), Lagos State (2023), and Bauchi State (2025) — four jurisdictions, four procurement processes, eight years of sustained field operation, aligned with the FCT Urban Traffic Control Master Plan.
Stack: Dual-band RF (433 MHz + 2.4 GHz), Wi-Fi, embedded firmware, field-configurable parameters, die-cast weatherproof enclosure with IP-rated connectorisation, 9–36 V DC.
SmartSAV Energy Management Platform (v1.0 → v2.0)
The product. SmartSAV is an end-to-end embedded power-management product family for Cosgrove estate developments, developed under CyberFlux Nigeria Ltd. I lead its hardware and firmware across the v1→v2 architecture — board-level design and troubleshooting through prototype, first-article, and field-deployment phases, including DFM / DFT handoff to contract manufacturers.
v1.0 — monitoring (~160 domestic units, Cosgrove Wuye). Estate-wide LoRa-based normalised energy monitoring with a custom TDMA schedule, achieving 99.2% uplink reliability over 2 km. The TDMA cycle's latency made it monitoring-only — which set the brief for v2.
v2.0 — real-time control (~40 systems, Cosgrove Katampe). GSM / Wi-Fi telemetry with on-board STM32 / ESP32 edge control and a full onboard power stack: UPS / ATS, battery monitoring, relay sequencing, solar charging. Modbus RS-485 integration with JSY-MK-323 three-phase meters (IEC 62053-21 Class 1), solar inverters, and BMS, plus Cummins PowerCommand generator monitoring via Modbus RTU and a WebSocket dashboard with threshold alarming.
Stack: STM32, ESP32, LoRa RF, GSM, Wi-Fi, Modbus RS-485 / RTU, Node.js, custom PCBs (KiCad).

Recognised the establishment and leadership of the Department's first traffic-light maintenance team and the successful direct-labor installation of the FCTA's first wireless signalized intersection. The commendation became the basis for the team's permanent appointments in 2019.
Verbal Commendation & Cash Prize — AC-Wired Traffic Signal Controller Reverse Engineering
Received in 2014 from the Transportation Secretariat, FCTA. Recognised the board-level reverse engineering of failing imported AC-wired traffic signal controllers and the rollout of a maintainable equivalent across multiple FCT intersections, breaking a recurring import-spend cycle.
