QA Automation Engineer at Mr. Cooper

December 1, 2024 - Present

Refactored the Playwright JavaScript automation framework with a fixtures layer, custom helper classes, and environment config files to enable cross-environment runs (dev, QA, staging) without code changes; reduced CI failures from ~40% to under 5% in 6 weeks. Implemented Page Object Model (POM) with module-specific page classes for loan application, document upload, and payment, sharing auth and test data via global fixtures for consistent onboarding. Applied Cucumber BDD (Gherkin) for business-critical loan workflows; used plain Playwright for lower-level regression and API tests to keep the suite lean. Diagnosed and resolved flaky tests in CI using trace viewer and video capture, fixed race conditions, and added test-runner retries to flag genuinely unstable tests. Performed API testing with Playwright APIRequestContext, authenticated via REST, triggering loan state transitions through API calls and verifying UI consistency to close front-end/back-end gaps. Integrated Playwright int

QA Engineer at Tanla Platforms

May 1, 2022 - January 1, 2024

Worked on high-throughput telecom messaging platform; established performance testing using JMeter from scratch, scripting top-5 high-traffic API endpoints with production logs, and running load, stress, spike, and endurance tests with Jenkins HTML dashboards for per-build performance trends. Identified a DB connection pool bottleneck (undersized HikariCP) causing degraded throughput beyond 800 concurrent users and implemented backend fixes that improved throughput by 35%. Set up Appium with XCUITest on BrowserStack for iOS automation validating carrier-side messaging client flows, DLT compliance, and promotional/transactional SMS handling. Conducted manual testing for unicode SMS, long-message concatenation, sender-ID validation, opt-out keyword processing, DND registry compliance, and SMPP integration. Configured Grafana/Prometheus dashboards for live CPU/memory/latency monitoring during load tests and traced production slowdown to a missing DB index, validating the fix with targeted

QA Engineer at HealthPlix

October 1, 2019 - May 1, 2022

Started as a Manual QA Engineer validating clinical workflows for an cloud-based EMR and FDA REMS portal; progressed to automation by building a Selenium WebDriver (Java) framework using Page Object Model with a base page and reusable components, and leveraging TestNG for test grouping and parallel execution. Built REST-assured API test collections to validate contracts, status codes, and data integrity; used WireMock to stub third-party insurance payer APIs. Validated Kafka async workflows and HIPAA role-based access/OAuth 2.0 security. Integrated validations into Jenkins pipelines and logged defects in Jira with steps, screenshots, and DB outputs; reconciled UI, API, and database results.
