Summary
Project-focused Electrical, Instrumentation & Controls engineer with end-to-end delivery experience across energy, resources, and advanced R&D. I’ve managed large E&I portfolios at Santos (reliability & operations, Port Bonython) and led niche bespoke projects up to $500k TCV at Ohmni, spanning HV/LV design, protection/coordination, VSD/drive integrations, PLC/SCADA, and data/reporting automation. Background includes Collins-class LoTE systems/detailed design at ASC (holding NV1), microgrid and custom energy storage prototyping, and embedded/PCB work. Anchored in AU standards (AS/NZS 3000, 2067, 60079) and rigorous MoC/QA. Known for stabilising plants, de-risking commissioning, and turning cross-disciplinary teams (AU/PH) into predictable delivery with zero LTIs under my control. Equally comfortable on the tools and in the boardroom: technical depth in controls/OT and the pragmatism to scope, plan, vendor-manage, and close.

Work History
Electrical and Control Systems Engineer
Ohmni
01.2024 - Current
- Co-founded Ohmni and delivered projects up to $500k TCV, keeping positive gross margins and completing all contracted scopes on time and to spec across mining, energy, and agriculture.
- Delivered a Flywheel Energy Storage System (FESS) prototype to 14,500 rpm using a PM-SynRM and Vacon/ABB drives as well as custom Power Electronics; Stabilised closed-loop operation end-to-end, and verified regenerative operation under full speed range testing.
- Designed and commissioned multi-axis electromagnetic controllers for precision off-loading: 0–10 V analog control, up to 25 A continuous, PLC-integrated; improved settling/hold behaviour to enable reliable high-speed spin-ups and safe decals with customised cascaded control algorithms.
- Engineered EMI reliability issues on high-speed rigs (e.g., 128-tooth and above TTL encoders), introducing shield/ground schemes and parameter templates that cut commissioning iterations by ~30% and improved signal integrity at max rpm.
- Built production SCADA/Dashboard stacks (Ignition + bespoke web UI) covering hundreds of tags and dozens of KPIs; reduced weekly ops reporting from ~4 hours to
- Contributed to microgrid and HV interfacing deliverables (protection coordination reviews, switching plans, isolation/MoC): executed field work with zero safety incidents under my control, aligned to site HV rules and LOTO.
- Created the modular Ohmni Platform (React/Node): shipped productionised containers for dashboards, reporting, and engineering design automation with >99% pilot uptime, handling continuous telemetry ingest and role-based access for client users.
- Orchestrated AU–PH delivery (engineering + BDM): standardised ADRs, MoC, code reviews, and QA checklists; improved estimate-to-actual variance on jobs to within ±10–15% via gated design reviews and test scripts.
- Scoped, priced, and closed niche service packages (controls/SCADA/energy) all while running marketing, proposals, and financial planning.
Software and Control Systems Engineer
ASC
01.2023 - 01.2024
- Contributed to the Life-of-Type Extension (LoTE) program on Collins-class submarines, delivering systems and detailed design packages for priority upgrades through peer, PDR, and CDR reviews with no major actions.
- Produced end-to-end control systems deliverables—schematics, cable schedules, I/O lists, load/voltage-drop and thermal calcs—for cooling systems, power distribution, and electronic control panels, aligned to defence/maritime standards and shipyard practices.
- Defined and documented upgrade pathways for control-panel PCBs (obsolescence, reliability, DFM/DFA), including interface/system updates and qualification test requirements to protect backward compatibility and reduce integration risk.
- Authored detailed technical reports, design justifications, test procedures, and work instructions, enabling reproducible builds and clear acceptance criteria for production and commissioning teams.
- Supported configuration and change management (ECR/ECO), risk assessments (incl. FMECA-style analyses), and verification plans, improving traceability and reducing rework during build and fit-out.
- Coordinated daily with production, QA, and supplier stakeholders to de-risk install/commissioning, resolve non-conformances, and unblock long-lead procurements on the critical path.
- Ensured designs reflected maintainability and safety constraints (access, isolation/LOTO, redundancy, EMC/earthing, segregation), improving serviceability and inspection clearance.
- Received NV1 security clearance during tenure at ASC, enabling contribution across restricted work packages.
Electrical and Instrumentation Engineer
Santos
11.2020 - 07.2023
- Reliability & Operations supporting Cooper Basin assets and specficially Port Bonython midstream plant; delivered risk-based investigations (DEM, FEA, RCA/5-Why) and implemented fixes that eliminated repeat failures and stabilised plant runtime.
- Managed an annual E&I project portfolio exceeding AUD $5M from concept/FEED through detailed design, procurement, construction, commissioning, and handover.
- Served as the sole Operations Engineer for Port Bonython, coordinating daily operations with maintenance/HSE, planning isolations and permits (LOTO/PTW), executing maintenance windows, and leading safe restarts through key milestones.
- Optimised control logic and protections across MCCs, VSDs, instrument loops, ESD/SIS, and fire & gas systems; rationalised alarms and tuned PID loops to reduce nuisance trips and improve stability.
- Drove RCM2 and reliability upgrades for critical motors and instruments. Setting PM strategies, deploying condition monitoring (thermography, vibration trending, valve/loop diagnostics), and improving mean time between failures.
- Completed hazardous area (EEHA) compliance tasks per AS/NZS 60079. Classification reviews, inspection campaigns, remediation of non-conformances, and drawing pack updates.
- Performed LV/HV studies (load flow, voltage drop, motor starting checks, protection/coordination screening) and verified cable sizing and switchgear settings against site standards.
- Produced E&I design deliverables; single-line diagrams, loop drawings, I/O lists, instrument datasheets, cause-and-effect matrices. Authored test procedures, commissioning plans, and work instructions.
- Led vendor interfaces (FAT/SAT, NCR resolution, punch-list closure) and unblocked long-lead procurement on the critical path.
- Maintained MoC/ECR traceability and improved CMMS data quality to support planning, spares, and reliability reporting.

- Configured Windows (and light Linux) environments, drivers, firmware/BIOS, device encryption, VPN clients, and user profiles. Ensuring stable, repeatable workstation setups.
- Provided L1/L2 support using a ticketing system (e.g., Jira/ServiceNow): triaged incidents, performed root-cause analysis, and closed tickets with clear knowledge-base documentation for future reuse.
- Wrote lightweight automation in PowerShell to standardise software installs, log collection, and configuration checks, cutting manual effort and variability in builds.
- Supported small office network needs (DHCP/DNS printer adds, VLAN-aware switch port requests, Wi-Fi troubleshooting) and coordinated with admins on access control changes.
