At Advarra, I design multi-agent delivery workflows and quality gates for a HIPAA-regulated clinical-trial intelligence product. Our seven-engineer team now completes in roughly a day work that previously took a week under Scrum.

At Wabtec, I led a four-engineer QA squad through rail-platform MVP validation, executing 474 unique tests across 175 requirements in six days. I rebuilt regression coverage that surfaced 70% more pre-deployment defects and reduced client-reported issues by 45%.

I build the test layer and the practice around it: Playwright and Selenium automation, Jenkins pipelines, API and microservice coverage, onboarding, documentation, and traceability from requirements to tests. My full-stack development background helps me read the implementation, not only the ticket.

I also teach microprocessor architecture at Pontificia Universidad Javeriana, applying the same discipline of root-cause analysis, verification, and performance thinking from low-level systems to production software.
