QA Infrastructure Platform (Built from Scratch)

Production-grade systems that tie the entire testing lifecycle together:

Repository What It Does
ci-quality-gate-engine Multi-signal CI/CD quality gate - aggregates test results to produce ship/no-ship verdicts
test-data-factory Schema-driven test data generation with relationship integrity and compliance masking
flaky-test-detective Statistical flaky test detection, root cause classification, quarantine management
ephemeral-env-controller On-demand PR-based test environment provisioning with TTL and resource tracking
api-chaos-testing-engine Chaos engineering for APIs - fault injection, resilience scoring, circuit breaker validation
api-mock-gateway Configurable API mock gateway with latency simulation and contract validation
qa-test-orchestrator Test suite scheduling, execution orchestration, and multi-environment reporting
feature-flag-engine Feature flag evaluation engine with gradual rollouts and A/B testing
