Global Bank Payment Gateway Refactor
A Tier-1 bank ran a 14-day manual regression cycle blocking every release of its payment gateway, causing critical fixes to queue for weeks.
Designed and shipped a Selenium/Java automation framework with API-layer test orchestration, parallelized across 200 containers in their private cloud.
Regression cycle compressed from 14 days to 36 hours. Production incident rate fell 62%. Annual QA spend reduced by $2.1M.
