Global Bank Payment Gateway Refactor

85% less manual QA
Problem

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.

Solution

Designed and shipped a Selenium/Java automation framework with API-layer test orchestration, parallelized across 200 containers in their private cloud.

Outcome

Regression cycle compressed from 14 days to 36 hours. Production incident rate fell 62%. Annual QA spend reduced by $2.1M.

Electronic Health Records Cloud Migration

0% downtime cutover
Problem

A 15-year-old monolithic EHR system on Windows Server was failing audits and could no longer scale to a planned national rollout serving 4M+ patient records.

Solution

Strangler-fig migration to .NET 8 microservices on Azure with event sourcing, FHIR-compliant APIs and full HIPAA-grade observability.

Outcome

Zero downtime during cutover. 3× faster patient lookup. Passed HITRUST certification first attempt.
