Kumar Saheb

I’m a Lead SDET with 12+ years of experience in test automation, quality engineering, and QA leadership across Fintech, Wealth Management, E-commerce, and ERP domains. I’m known for architecting scalable automation frameworks from scratch—covering web, mobile, API, and performance—then driving measurable automation coverage fast.

At OnePay (Fintech subsidiary of Walmart), I’m the sole automation lead for the India Banking Team, owning end-to-end strategy across mobile (Detox), web (Playwright), and API (SuperTest/Bruno). I’ve used Claude Code and Cursor to accelerate test generation by ~40%, and I’ve built n8n workflows that auto-trigger test runs, aggregate results, and post Allure summaries to Slack.

I also spearhead LLM-assisted test case generation to uncover edge-case scenarios in banking flows, leveraging prompt engineering to surface gaps missed in manual review. I’ve led deep-link automation initiatives, integrated reusable frameworks into CI/CD with GitLab CI/CD and Allure reporting, and maintained org-wide tooling like QA Lambda (AWS Lambda serverless test command repository) and a centralized Bruno API repository.

Previously, I increased automation coverage from 20% to 80% within 6 months at Fidelity Investments, led a Protractor-to-Cypress migration that reduced execution time by 30%, and embedded smoke, unit, and integration tests into developer pipelines for instant feedback. Across my career, I’ve mentored QA teams, debugged production incidents using observability tools, and executed load/performance testing with K6 (and Gatling) to protect quality at speed.
