Validated complex transaction lifecycle scenarios end to end authorizations, clearing and settlement, postings, fees, disputes, chargebacks, and reconciliation across TSYS and downstream mainframe systems. Performed processor integration testing between Citi card applications and TSYS, validating inbound and outbound file exchanges, transaction confirmation codes, timestamps, and posting accuracy across system boundaries. Tested dispute and chargeback workflows including case initiation, representment, provisional credit, and final resolution, verifying accurate adjustment and posting on cardholder accounts. Validated daily settlement and reconciliation cycles by comparing TSYS settlement files against mainframe balances and general ledger postings, identifying out-of-balance conditions and monetary discrepancies before production impact. Validated fee assessment and cycle posting logic (late fees, interest, annual fees) on private label and co-brand card accounts, confirming accuracy against documented acceptance criteria. Designed and developed scalable BDD-based automation frameworks using Java, Selenium WebDriver, Cucumber, Gherkin, TestNG, JUnit, and Page Object Model to support functional, regression, smoke, sanity, and end-to-end testing for card applications. Built and maintained reusable Selenium automation scripts for critical customer-facing and internal banking workflows including card issuance, activation, transaction processing, OTP-based authentication, payment checkout flows, and payment session management. Performed integration and end-to-end testing across banking application, service, and database layers, validating data flow, transaction accuracy, and system-to-system integrations before each release. Ensured established QA processes and standards were followed at every stage of the SDLC, from requirement analysis and test design through execution, defect management, and release sign-off. Worked closely with onshore QAs and developers to reproduce and resolve defects, review automation coverage, and align on test approach, consistently delivering quality results with minimal oversight. Executed manual functional, regression, UI, and integration testing across private label and co-brand card processing systems to validate business workflows and user journeys. Performed API testing and automation using Postman, RESTful APIs, SOAP services, JSON, and XML to validate request/response payloads, authentication flows, status codes, error handling, and microservices integration with payment systems and Fiserv. Executed database testing and backend validation using SQL queries across Oracle, SQL Server, and MySQL to verify transaction data, customer records, payment status, audit logs, and data consistency across UI, API, and database layers. Extracted and validated data from mainframe and TSYS databases using SQL queries to verify card data integrity, transaction records, balance updates, settlement postings, and customer information processing accuracy. Validated Fiserv payment processing system transactions, verifying payment statuses (Approved, Declined, Pending) and ensuring monetary data accuracy across payment gateway integrations. Integrated UI and API automation suites with Maven, Jenkins CI/CD pipelines, Git, GitHub, and Zephyr to enable continuous testing, scheduled regression execution, build verification, and faster release feedback. Leveraged GitHub Copilot and Friday AI for intelligent automation script drafting, generating card application test cases automatically and reducing manual scripting time by 40% while maintaining code quality. Supported shift-left testing by participating early in requirement analysis, story grooming, sprint planning, test design, and development discussions to identify automation scope, test data needs, and quality risks. Collaborated with business analysts, developers, product owners, and scrum teams to refine acceptance criteria, validate user stories, perform defect triage, and reduce defect leakage into UAT and production. Logged and tracked defects in JIRA with detailed reproduction steps, screenshots, and severity levels, managing the complete defect lifecycle from identification through resolution and verification. Conducted PCR (Post Change Request) testing to validate code changes in card processing logic and payment workflows, ensuring no regression impact before production deployment. Conducted internal review cycles (2 weeks pre-UAT) with Citi stakeholders and external client review sessions (1 week pre-UAT) to validate test scripts, refine test data, improve coverage, and align on UAT entry criteria. Executed UAT testing within defined timeframes, delivering daily EOD test execution reports with status summary, card transaction metrics, and payment processing data.
