Summary

I’m a Chartered Professional Engineer (Australia) and a licensed Professional Engineer in Canada, with global recognition in Reliability, Availability, Maintainability, and Asset Management. I lead high-performing reliability teams, delivering data-driven strategies to enhance system performance, optimize maintenance, and reduce lifecycle costs. My technical expertise includes FMEA/FMECA, Fault Tree Analysis, RBDs, Weibull modelling, Monte Carlo simulations, lifecycle cost analysis, and preventive/corrective maintenance planning with CMMS integration.

My work has generated over $5.2M in project savings and earned multiple industry awards, including the prestigious “Eight Inch Award” and the Australian Government’s Distinguished Talent Award for global leadership in engineering. I’ve published 10 international journal papers and actively mentor emerging STEM professionals while continuing to deliver high-impact engineering outcomes.

Work History

Reliability & Maintainability Manager

Downer Group Australia
06.2024 - Current
  • Led the development of comprehensive Failure Modes and Effects Analysis (FMEA) to identify service-affecting failures, assess equipment criticality, and support design improvements.
  • Directed the creation of reliability block diagrams (RBDs), fault tree analysis (FTA), and Weibull life data analysis to model failure behavior, calculate system reliability metrics (e.g., MTBF, reliability growth), and validate compliance with performance targets.
  • Oversaw reliability apportionment modelling across major subsystems including control systems, communications, power supply, and mobile platforms, ensuring target alignment with system-level requirements.
  • Developed and validated system-level reliability predictions using field data, statistical methods, and failure rate databases (e.g., MIL-HDBK-217, NPRD).
  • Directed and reviewed the development of maintainability analysis including Maintenance requirements analysis and the technical maintenance plan.
  • Provided oversight on the development of RAM performance models to support life cycle cost assessments and availability forecasting (e.g., Ao, uptime, failure frequency).
  • Led technical collaboration with system designers, systems engineers, and interface managers to embed reliability requirements into the design baseline from concept through detailed design.
  • Reviewed and contributed to test plans and validation strategies to confirm that reliability and maintainability characteristics were demonstrably integrated into the final product.

Reliability Engineering Manager

01.2023 - 06.2024
  • Conducted comprehensive Failure Modes and Effects Analysis (FMEA) to identify service-affecting failures, determine component criticality, and define maintenance tasks at system and sub-system levels.
  • Directed the creation of asset hierarchies and functional location structures aligned with ISO 14224 and ISO 55000, forming the basis for maintenance strategy development and CMMS integration (e.g., Maximo).
  • Performed maintenance requirements analysis, including task profiling, preventive and corrective maintenance strategy definition, and maintenance task grouping for work packaging efficiency.
  • Led maintainability modelling including Mean Time to Repair (MTTR), repair crew requirements, tool/part dependencies, and maintenance access constraints.
  • Delivered reliability block diagrams (RBD), fault tree analysis (FTA), and Weibull life data modelling to simulate failure behaviors, calculate MTBF/MTTF, and validate reliability growth across lifecycle phases.
  • Developed corrective maintenance backlogs and preventive maintenance plans informed by reliability predictions, historical data, and failure rate libraries (e.g., MIL-HDBK-217, NPRD).
  • Oversaw the development of RAM models to forecast operational availability (Ao), system uptime, and lifecycle support cost under varied failure and maintenance scenarios.
  • Supported the design and configuration of asset management systems by providing technical inputs on failure modes, inspection frequencies, replacement intervals, and performance thresholds.

Lead Reliability Engineer

CN
02.2021 - 01.2023
  • Directed the application of reliability analysis techniques such as Failure Modes, Effects, and Criticality Analysis (FMECA), Fault Tree Analysis (FTA), Root Cause Analysis (RCA), and Reliability Block Diagrams (RBD) to identify systemic failure risks and improve operational reliability.
  • Facilitated the integration of reliability data into maintenance strategies by linking observed failure patterns to corrective and preventive maintenance actions through structured condition monitoring and trend analysis.
  • Developed and refined preventive maintenance (PM) plans using reliability tracking insights, asset performance metrics, and failure data to extend asset life, reduce unplanned downtime, and optimise inspection intervals.
  • Oversaw the setup and execution of corrective maintenance workflows, using historical reliability data to refine maintenance response plans and adjust resource allocation based on criticality and frequency of failures.
  • Implemented and managed Failure Reporting, Analysis, and Corrective Action System (FRACAS) frameworks to enable data-driven reliability growth and continuous maintenance process improvement.
  • Championed asset management strategies, including critical spare parts definition, Life Cycle Cost (LCC) modelling, and Total Maintenance Planning (TMP) to improve maintainability and cost predictability.
  • Collaborated with engineering, operations, and maintenance teams to align reliability objectives with practical supportability outcomes across concept, design, and operational phases.
  • Supported the configuration and integration of Computerized Maintenance Management Systems (CMMS) such as Maximo, ensuring accurate asset hierarchies, task libraries, failure codes, and maintenance schedules.

Senior Systems & Reliability Engineer

Dalkiranlar Group
