  • Production and UAT incident triage

Experience

Selected professional experience from the current resume. LinkedIn provides the detailed public chronology.

  1. Quality Assurance Engineer III

    Healthcare SaaS

    Current professional focus

    • Validate pricing, cost-of-care, eligibility, claims, provider search, and user-interface workflows across complex client configurations.
    • Author Playwright regression coverage with reusable fixtures, data-driven parameterization, helpers, and page abstractions for authentication, client data flows, and cost assertions.
    • Lead release validation across multiple environments and support escalations with API traces, observability logs, and database evidence.
    • Diagnose eligibility and cost logic by decoding EDI 270/271 responses and coordinating resolution across engineering, configuration, data, and client stakeholders.
    • Design deterministic AI workflows, CLI routing, and reusable agent skills with explicit evidence requirements and reviewable outputs.
    • Build evidence-first investigations that distinguish facts, inferences, and uncertainty, then trace issues across APIs, logs, and data.
    • Implement read-only defaults, sensitive-data redaction, human approval gates, and contract checks for routing, evidence schemas, and workflow consistency.
    • Reviewed 9,999 records with approximately 50 expected matches, saving 8+ hours per relevant investigation.

  2. Quality Assurance Engineer

    Embedded systems, robotics, and semiconductor inspection

    Technical foundation

    • Designed test coverage across embedded systems, desktop applications, and APIs that supported semiconductor and wafer-inspection workflows.
    • Defined robotics test matrices covering edge cases, failure modes, and recovery paths for production equipment.
    • Automated repeatable graphical-interface, API, and script-level validation in Python.
    • Created test manuals and troubleshooting guides that made defect reproduction repeatable across QA, engineering, and field teams.
    • Led cross-functional improvements to silicon wafer cassette analysis, reducing processing time by 50% while maintaining quality standards.

  3. Lead Quality Control Engineer

    Class II medical device

    Regulated systems

    • Built and led a production quality-control function for a Class II BiPAP medical device.
    • Established procedures, trained technicians, and standardized repeatable testing across manufacturing stations.
    • Applied calibration, instrumentation, and traceable validation practices in a regulated production environment.
    • Debugged and extended Python and Arduino scripts for instrumentation, measurement integrity, data logging, and repeatable testing.

  4. Quality Assurance — Fintech

    Blockchain and digital assets

    Early QA experience

    • Alpha-tested a gaming and streaming platform, configured Qt wallets and masternodes on headless Linux servers, and verified defect fixes with developers.
    • Ran testnet nodes and scripts in Linux and Unix environments to validate interoperability and throughput across financial-system components.
