Mar 2022 - now
- Translated interface requirements into a system architecture model, allocating timing and failure behavior to subsystems. Maintained traceability from each requirement to its verification procedure.
- Used MATLAB modeling to test sensor noise and delayed inputs against the control assumptions; recorded failed cases and updated interface documentation before the integration review.
- Provided mentoring through peer reviews of interface requirements, tracing each failure case to a verification procedure. Used a worked sensor-timeout example to resolve ambiguous acceptance wording and retained the reviewed model for subsequent design checks.
- Traced interface requirements from system specifications to integration tests; resolved a mismatched timing assumption between subsystems before the acceptance review.
- Owned interface validation using MATLAB models and traceable requirements, resolving timing mismatches between two subsystems before integration testing.
- Published system-architecture documentation linking each acceptance test to its requirement, reducing unowned review actions from 17 to 6 at the next baseline review.

Systems Engineer
Jan 2019 - Feb 2022
- Tested recovery of 14 critical services from clean infrastructure definitions. Held the reliability gain through the next operating review.
- Reviewed a proposed change against the existing interface contract, reproduced a reviewer’s edge case, and added the missing test or example before merging the change.
- Investigated a failure reported by a downstream team using the exact version and input they supplied. Reduced it to a reproducible test, delivered the fix with compatibility notes, and confirmed the original case passed before closing the report.
Selected project
Systems Engineer — independent case study
Project owner
Feb 2024 - Jun 2024
- Consolidated 31 host alerts into 9 symptom-based signals with runbooks
- Built an isolated fixture with normal, malformed and interrupted inputs; recorded the expected response before running the implementation so failures were distinguishable from a changed assumption.
- Packaged the reproduction steps, configuration and regression tests with the project; checked the instructions from a clean environment and documented the unsupported cases instead of claiming production readiness.
- Owned the independent regression fixture using isolated inputs, resolved a failing edge case and released a reproducible test package with expected outputs.

- Published an independent technical note using the project’s before-and-after traces, explaining the failed assumption, regression coverage and cases the implementation does not support.
