Re‑architected the bank’s distributed quality platform into a cloud‑native, event‑driven pipeline. Deployed Playwright & REST‑assured tests as immutable containers orchestrated by AWS ECS/Fargate Spot, shrinking feedback loops from 4 hrs to <60 mins while saving $180K annually.Evangelized contract‑first development: embedded Pactflow verification across 230+ micro‑frontends and payment rails (ACH, FedNow, RTP, Zelle), resulting in zero schema rollbacks post‑release.Piloted a private generative AI assistant (Llama 2 fine-tune) on internal policies; built a 250-scenario Playwright red team suite for hallucination, PII leakage, and bias checks—kept error rate <1% during beta.Maintained Terraform IaC patterns and wired Snyk/Trivy scans into GitHub Actions so every merge leaves an audit trail—simple, boring, and reliable.Codified “Quality‑as‑Code” infrastructure in Terraform/CDK, gated by Snyk IaC and Trivy, achieving SOX‑attestable traceability through GitHub Actions with OIDC‑based secretless deploys.Wrote and debugged “bread and butter” SQL and bash scripts that archive logs, clean up S3 buckets, and rotate test data—small things that keep pipelines humming.Conducted performance testing with Playwright and led machine learning-based anomaly detection, improving system responsiveness and early issue detection.
