Case Studies
Selected work
Four engagements from roughly a year of test automation work on a multi-tenant commerce operations platform: a React micro-frontend application, a backend-for-frontend, and several GraphQL subgraphs behind a federated router.
Client, product, service and people names have been removed, and figures are counted from version control rather than estimated. We will go deeper on any of these on a call, under NDA where that helps.
API contract and authorisation testing on a federated graph
62 API test cases, a persistence read-back module called from 44 sites, and 22 silent skips turned into hard failures.

Taking over a red pipeline
12 quarantined tests restored in 20 days, leaked test data cut from 7 records per run to zero, and a suite that stopped killing other teams' pipelines.
- CI
- flaky tests
- test data management
- pipeline stability
An AI-augmented QA workflow
A custom agent skill, live locator verification through MCP, and an enforcement layer that blocks a commit until the self-audit is clean.
