Senior SDET | Playwright + Python/TypeScript | Healthcare Data QA | CI

I'm a Senior SDET with 5+ years building test infrastructure that scales — from manual QA and test planning through full automation, CI/CD quality gates, and observability. My specialty is healthcare and data-heavy platforms, where correctness isn't cosmetic — it's revenue and compliance. I work across the full QA spectrum: writing test plans and filing detailed bug reports, testing REST APIs directly via Swagger and browser console, building Playwright suites from scratch, and designing CI pipelines that catch defects before they reach production. Recent work: — Currently embedded with a healthcare data products company, building QA coverage for billing and claims data pipelines. This work sits at the intersection of data quality, API validation, and healthcare domain rules (CPT codes, payer logic, denial workflows) — an area where most automation engineers don't have domain depth. — Sole QA engineer for a luxury e-commerce marketplace during their pre-launch sprint. Built the QA process from zero: structured test plans, payment flow validation (Stripe, 3DS), end-to-end offer/negotiation testing (API + UI), 15+ prioritized Jira bugs, and real-time fix verification with frontend/backend engineers. Core purchase, offer, and checkout flows validated for soft launch within two weeks. What I bring to your team: Manual QA and exploratory testing — structured test plans, detailed bug reports with reproduction steps, prioritized by severity API testing — REST endpoint validation, Swagger, Postman, contract testing with JSON Schema and Pact Test automation — Playwright (UI, API, E2E), Python, TypeScript, Robot Framework Data quality testing — SQL-based validation, pipeline verification, healthcare billing datasets CI/CD quality gates — GitHub Actions, AWS Lambda, Azure DevOps Observability — Postgres, Grafana dashboards, Slack alerting for test health Deep domain experience in healthcare billing (I spent two years inside a medical practice before engineering, and founded ClaimReady, a pre-submission claim validation engine) — so I bring both engineering depth and product-owner perspective to QA work.
