Work History
Senior Systems Engineer
G2 OPS, INC.
02.2023 - Current
- Developed and implemented SysML-based system models for the NAVSEA03 SABER Program, ensuring system design alignment across Government, contractor, and system engineering teams
- Strengthened customer confidence and partnership by working with NAVSEA, NUWC, and PMS397 stakeholders to validate and refine system configuration and requirements
- Led requirements development, deriving requirements from activity diagrams before mapping them to system components in the SysML model leading to the submission of a successful System Requirement Document (SRD) for SABER
- Enhanced safety and operational readiness by implementing improved validation processes and model-based verification techniques for versioning in SysML models
- Simulated operational availability (Ao) for system parametric model based on reliability of subsystems and their components
Reliability & Maintainability Systems Engineer
SAIC (Engility)
08.2018 - 02.2023
- Developed an MBSE-driven Failure Modes, Effects, and Criticality Analysis (FMECA) framework, integrating standards like MIL-STD-1629 'Procedures For Performing a FMECA', SAE1025 'FMEA/FMECA Global Standard', and DI-SESS-81495 'Failure Modes and Effects Criticality Analysis' to enhance system reliability
- Developed digital sustainment models aligned with DoD compliance frameworks, ensuring traceability with MIL-STD-1629
- Created SysML-based models to replace document-based failure modes and criticality analysis reporting, improving data traceability and reducing design cycle times for service programs
- Piloted the integration of XML files with the Defense Standardization Program Office’s (DSPO’s) database (ASSIST), giving defense programs the ability to automate data ingestion, improve traceability of standardization documents, and enhance interoperability with contractor systems
