Humana, USA QA Automation Engineer Jan 2025 – Present

• Engineered a Playwright + TypeScript automation framework with parallel execution and API virtualization to resolve regression delays, boosting test coverage 63% and accelerating release cycles by 45%.

• Automated REST Assured and Postman-based API workflows for claims, eligibility, and enrollment to eliminate repetitive manual testing, improving accuracy and reducing verification time 70%.

• Executed large-scale JMeter and BlazeMeter load tests on core eligibility and claims APIs to address performance gaps, improving throughput and response efficiency by 38% post-optimization.

• Implemented a Cucumber + TestNG BDD framework aligned to CMS and HIPAA rules to eliminate requirement misinterpretation, reducing ambiguity-related defects by 95% across teams.

• Optimized UI, API, and FHIR validation using Selenium Grid, JDBC, and contract testing to fix integration gaps, decreasing high- impact defect leakage across releases by 52%.

• Integrated automated test suites into Jenkins and GitHub Actions CI/CD workflows with Docker to standardize deployments, increasing pipeline stability 41% and strengthening continuous delivery output.

• Strengthened system compliance posture by embedding OWASP ZAP scans, secure secret policies, API governance, and Okta identity verification, supporting HIPAA and HITRUST regulatory standards.

• Collaborated with clinical, operations, and product stakeholders to validate claims exception flows, provider accuracy, and authorization logic, reducing critical production defects by 27% through improved test coverage. Persistent Systems, India QA Engineer May 2021 – Sep 2023

• Built a scalable automation framework using Selenium, Java, TestNG, Page Object Model, and Extent Reporting, improving regression efficiency by 58% across fintech release cycles.

• Performed API testing using Postman, backend verification using SQL, and log analysis for microservices, reducing integration- level defects by 40%.

• Designed and maintained smoke and sanity suites integrated with Jenkins and Git, improving deployment validation consistency and reducing feedback time.

• Developed reusable automation libraries for authentication, input validation, dynamic data generation, and utility functions, increasing scripting speed by 35%.

• Conducted performance and load testing using JMeter for loan processing and billing modules, identifying concurrency issues and improving throughput stability by 22%.

• Executed detailed manual and exploratory testing for onboarding, loan lifecycle, repayment, and billing workflows, achieving 92% functional test coverage.

• Validated financial ledger entries, account reconciliation, and transaction accuracy using SQL, identifying mismatches that prevented major financial discrepancies.

• Collaborated with developers, business analysts, and product teams to clarify requirements, reducing misunderstanding-related defects by 30% and improving sprint delivery timelines. EDUCATION

Master of Science, Information Technology Management Oct 2023 – May 2025 ST. Francis College, NY, USA

PROJECTS

Web-Based Learning Portal – Automated Testing Suite

• Improved release quality by designing an automated suite using Selenium, Java, and TestNG to validate enrollment and assignment flows, reducing manual testing effort and ensuring stable weekly deployments through structured regression cycles. Microservices Billing System – API and Performance Validation

• Enhanced billing stability by building Postman API collections automated with Newman in CI and creating JMeter load scenarios, identifying latency issues and improving microservices response consistency across peak transaction periods.
