Architected a hybrid web automation ecosystem from scratch, transitioning critical enterprise workflows from Selenium WebDriver (Java) to Playwright (TypeScript), expanding web UI and responsive design coverage by 45%. Engineered custom Claude AI prompts and context engines for automated test script generation and runtime self-healing, accelerating regression velocity and increasing overall QA efficiency by 60%. Designed and implemented a scalable API automation framework using REST Assured and Java, programmatically validating multi-tier microservice response patterns, data models, and JSON schemas. Conducted manual API testing and payload validation using Postman, verifying authorization tokens, edge-case query parameters, and boundary conditions prior to framework integration. Executed end-to-end Mobile Manual Testing across Android and iOS real devices, evaluating feature parity, native gestures, background states, and responsive layout consistency. Designed a BDD Cucumber framework wrapped around Selenium/Playwright and REST Assured to facilitate behavior-driven development and seamless cross-functional collaboration. Constructed continuous testing pipelines within Jenkins, executing 350+ automated web and API test cases on every code commit to trigger immediate defect alerts. Optimized backend data validation by writing complex multi-table SQL queries to reconcile live database state transitions against API responses.

QA Analyst

LTIMindtree Ltd.

Dec 2021 - Oct 2024

Implemented a robust web automation framework using Selenium WebDriver and Java adhering to the Page Object Model (POM) design pattern to test the Duck Creek Billing application, dramatically reducing code duplication. Designed and maintained BDD Cucumber features and step definitions for core commercial insurance processing paths including FNOL, billing account creation, installment plan schedules, and invoice generation flows. Developed automated API test scripts using REST Assured to validate complex Duck Creek Server transactions, payload structures, and external payment gateway integrations, transitioning 40% of legacy manual validation into the automated regression suite. Led extensive manual API testing operations via Postman, constructing parameterized collection suites and environment variables to thoroughly validate complex JSON schemas passing through the Duck Creek Anywhere API layers. Executed targeted Regression, Smoke, and Sanity test suites covering complex commercial premium rating rules, installment schedules, and billing delinquency lifecycles, maintaining a 98% defect-detection accuracy rate. Executed comprehensive functional testing during the critical enterprise core platform migration to Duck Creek Claims V12, ensuring zero functional or data regression across legacy configurations and custom configurations. Authored and executed automated data-driven testing suites using TestNG and Maven, leveraging external data sources to validate multi-tier financial transactions, reserve changes, and claim indemnity/expense payment calculations. Conducted thorough backend data validation utilizing advanced SQL scripts to verify insurance premium calculations, transactional consistency, ledger entries, and historical claims migration integrity across microservices. Managed end-to-end defect tracking and lifecycles within Jira, tracing functional flaws back to specific Duck Creek Author configuration pages and generating comprehensive test reports and Requirement Traceability Matrices (RTM). Collaborated closely in an Agile environment with business analysts and developers to break down complex underwriting guidelines, policy line characteristics, and claim handling rules into structured functional test cases.
