Work History

Guarantee Engineer – U.S. Navy New Construction & Lifecycle Sustainment

GENERAL DYNAMICS NASSCO
San Diego, CA
07.2024 - Current

USNS EARL WARREN & USS Robert E. SIMANEK

KEY RESULTS

  • Built an engineering approved Kanban prioritization and lifecycle repair sequencing system that prevented scope drift, enforced validated technical need, and maintained lifecycle control. The structure prevented over $130,000 in potential cost overruns across two Navy hulls and earned direct praise from the department Director for transparency, cost discipline, and lifecycle accountability.
  • Led discrepancy closure and guarantee repair execution across two delivered Navy vessels, resolving 245+ guarantee discrepancies and completing corrections under budget.
  • Authored pressurized tank air testing safety requirements that removed safety hazards during readiness phases. These procedures were formally endorsed by the VP of operations and rolled into operational standards across construction programs.
  • Developed refueling evolution hazard signage and tank movement safety controls for fuel receipt, tank transfer, and removal operations, improving maintenance safety compliance, readiness posture, and procedural discipline. These procedures were formally endorsed by the VP of operations and the director of test and trials and rolled into operational standards across construction programs
  • Facilitated lifecycle aligned repair decision forums that strengthened sequencing logic, lifecycle condition assessment, cost control, and discrepancy prioritization.
  • Conducted lifecycle evaluations, feasibility analyses, subcontractor quote approvals, cost projections, and overhaul versus replacement assessments to support repair decisions.
  • Applied maintenance KPIs and CASREP aligned condition logic to enforce acceptance critical closure timing, repair quality, lifecycle plan alignment, and readiness criteria.

DAILY RESPONSIBILITIES

  • Provide repair policy structure and maintenance safety oversight for guarantee phase discrepancies and compartment readiness tasks.
  • Maintain overhaul aligned repair schedules outlining sequencing, lifecycle timing, acceptance milestones, and Test & Trials alignment.
  • Perform lifecycle assessments and failure mode logic to support cost, feasibility, subcontract, and repair path decisions.
  • Conduct shipboard surveys with engineering, subcontractors, and SUPSHIP to verify repair need, lifecycle risks, and acceptance conditions.
  • Communicate status through discrepancy dashboards, engineering briefs, and Test & Trials reviews to maintain cost, schedule, and lifecycle integrity.

USNS Robert F. Kennedy

  • Directed 65+ improvement initiatives tied to lifecycle sustainment, rework elimination, discrepancy cycle time reduction, schedule acceleration, cost avoidance, waste reduction, and throughput gains across new construction and guarantee cycles.
  • Led lifecycle sequenced build planning for C4I, Accommodations, Machinery tanks and elevator compartments, allowing turnover and government acceptance three weeks ahead of plan, advancing inspection timelines and reducing schedule risk exposure.
  • Authored a Ship Pipe Systems Technical Training Guide used for readiness preparation, system function learning, maintenance fundamentals, and lifecycle sustainment skills. The guide was endorsed and adopted by Upper ship’s Management leadership.
  • Standardized maintenance-based discrepancy routing, prioritization logic, lifecycle sequencing, and PMI aligned readiness triggers that improved closure velocity and sustainment planning discipline.
