Deep Playwright and TypeScript, strong API testing, and a track record of killing flake — suite reliability from 72% to 99.4%.
Professional Experience
QA Automation Engineer · Saltbox Software
Mar 2023 – Present
- Cut escaped production defects 63% by building a 1,200-case Playwright/TypeScript suite gating CI on the 15 revenue-critical user journeys.
- Shrank full regression from 3 days of manual passes to 45 minutes automated, unblocking the move from biweekly releases to daily deploys.
- Raised suite reliability from 72% to 99.4% pass-consistency by eliminating flake: network stubbing, deterministic waits, and a quarantine lane with a 48-hour fix SLA.
- Built the API test layer (600 contract and integration tests, Supertest) that catches breaking changes before the UI suite runs, cutting mean defect-detection time 80%.
- Cut per-release manual testing 30 hours by risk-scoring the regression matrix with the product team — automating the top tier, deleting 200 obsolete cases outright.
QA Analyst · Lakeshore Insurance Technologies
Jun 2019 – Feb 2023
- Wrote the team’s first automated smoke suite (Selenium/Java, 80 cases) cutting release-day verification from 6 hours to 20 minutes.
- Found and documented 400+ defects across 3 product lines, including a premium-calculation bug that would have misbilled 12K policyholders.
- Designed the test-case management standard (traceability to requirements) adopted across 4 QA analysts, cutting audit-preparation time in half.
Projects
Open-source: flakewatch
- Published a Playwright reporter that clusters failures by root-cause signature and tracks flake trends per test; 400+ GitHub stars, used by several teams in CI.
