Professional Experience

Lead Quality Assurance Engineer

MedImpact • San Diego, CA
  • Directed QA delivery across enterprise PBM platforms, ensuring test strategies validated both web applications and backend drug benefit workflows (REST/SOAP, Kafka, HL7/EDI 270/271, NCPDP transaction sets).
  • Applied AI-driven test generation in Python to create permutations of drug codes, benefit edits, and restriction scenarios — expanding coverage to uncover edge cases that impact patient safety and benefit accuracy.
  • Troubleshot complex drug data issues across distributed systems, using Oracle SQL/stored procedure analysis to validate formulary restrictions, benefit calculations, and cross-plan eligibility. Partnered with DBAs to trace errors in medical data pipelines and resolve discrepancies.
  • Built and maintained Java/Selenium WebDriver frameworks, integrated into Jenkins CI/CD and executed on Kubernetes-hosted Selenium Grid pods for scalable, reliable automation.
  • Used Grafana dashboards and kubectl to monitor QA/non-prod pods, analyze environment health, and perform restarts during test cycle incidents.
  • Collaborated with Product Managers and Engineers to review requirements, identify risks, and plan coverage for highly regulated workflows, balancing automation with exploratory testing on critical benefit and drug restriction logic.
  • Guided QA engineers in analyzing coverage — separating manual vs. automatable test cases — and scaling automation to cover repetitive transaction validation while preserving exploratory focus on high-risk clinical and compliance scenarios.
  • Advanced tooling and compliance integration (Xray/Jira workflows, Git branching strategies, NiFi file transfers) to streamline delivery and reduce operational risk in regulated healthcare systems.

Senior Quality Assurance Engineer

CareFusion • San Diego, CA
  • Led the development of a custom automation framework in C# with integrated REST/SOAP testing using Postman and ReadyAPI to support HIPAA-compliant healthcare applications hosted on AWS EC2.
  • Validated structured message formats (HL7, JSON, XML) and ensured alignment with federal security standards including HIPAA, NIST, and SANS.
  • Oversaw testing and deployment of system-level security patches using WSUS and PowerShell, supporting the reliability of offline medical devices in controlled QA environments.
  • Contributed to platform hardening efforts by incorporating virus scanning (ESET) into release cycles and partnering with infrastructure teams to deliver secure image deployments.
  • Worked cross-functionally to align test architecture with delivery milestones and operational risk management strategies.

Product Support Product Manager

Hewlett-Packard • San Diego, CA
  • Led technical support operations for software and hardware diagnostics, mentoring frontline teams on root cause analysis, test strategy, and effective escalation workflows.
  • Collaborated closely with product and engineering teams to identify and prioritize system-level defects, driving improvements in field stability across hardware platforms.
  • Analyzed recurring issues and shared actionable insights with stakeholders to influence release planning and strengthen quality gates.
  • Documented and proposed sustainable technical solutions to reduce resolution times and enhance end-user satisfaction across enterprise deployments.

Senior Quality Assurance Engineer

Mitchell International • San Diego, CA
  • Designed and executed automated test suites using C# and CodedUI to validate complex user workflows in RepairCenter, a mission-critical desktop application.
  • Conducted API performance testing using JMeter to assess scalability and reliability of endpoints integrated with the Apigee gateway.
  • Managed QA infrastructure using VMware vSphere, building and maintaining virtual environments to support high-throughput performance testing.
  • Collaborated with DBAs to optimize SQL Server-based data warehouses, tuning stored procedures to enhance data flow and reporting capabilities.
  • Maintained versioning and deployment permissions via AWS S3 for distributed application rollouts.
  • Provided mentorship to QA engineers, promoting consistency in automation practices and improving infrastructure readiness across the engineering team.

Automotive Technician

San Diego Dealerships
  • Completed General Motors ASEP Certification at Cuyamaca College and worked across multiple GM dealerships in San Diego as a bumper-to-bumper technician specializing in 15A and engine repair.
  • Applied standardized safety and hazardous waste handling practices while diagnosing and repairing mechanical, ignition, electrical, and emissions systems using industry-standard diagnostic tools.
  • Interpreted wiring diagrams and technical service bulletins to resolve drivability concerns, conducted smog inspections in compliance with BAR regulations, and ensured high-quality customer interactions through clear communication and accurate repair documentation.
