ILLUSTRATIVE DEMO · NOT A LIVE TESTENTERPRISE AUTOMATION PLATFORM01 — 05
Scalable UI & API automation
Built a Playwright-based automation platform for UI and API testing across applications and services. Coverage grew from about 15% to 85%, with 4,000+ test cases across four applications. Parallel execution through Azure DevOps reduced automated execution time by approximately 80%.
Regression: about 2 days to 6 hours
