Performed system testing, integration testing, regression testing, and User Acceptance Testing (UAT) for complex, multi-application telecom environments, translating business requirements and functional specifications into detailed test scenarios, test cases, and test data. Conducted backend SQL data validation to verify accuracy of customer orders, pricing rules, product configurations, promotions, contract terms, discounts, and billing outputs across tightly integrated enterprise systems.
Identified, documented, and tracked functional, integration, and data-related defects; collaborated closely with developers, business analysts, and operations teams to validate fixes, support Operational Readiness Testing (ORT), and assist with production release and post-deployment verification. Automated selected business-critical test scenarios using JavaScript and Selenium to improve regression coverage, coordinating testing activities across distributed teams to support multiple release cycles.
Supported system and integration testing for enterprise telecommunications platforms delivering wireline and wireless services, including customer account management and service order workflows. Executed test scenarios validating service order creation, provisioning flows, and billing initiation, ensuring accurate end-to-end telecom service lifecycle processing.
Participated in requirements analysis and test planning, translating business and functional requirements into executable test cases and test data, and validated application behavior against telecom service logic, pricing rules, and provisioning dependencies. Identified, documented, and tracked functional and data-related defects, collaborating with development teams to validate fixes, and supported UAT while maintaining test execution records and documentation to ensure traceability.
Began as a Junior Process Associate supporting healthcare billing and claims processing, and later transitioned into a Software Testing Engineer, applying healthcare domain expertise within Revenue Cycle Management (RCM) environments. Performed functional, system, and regression testing for healthcare billing and RCM applications including ProBill, validating end-to-end workflows such as charge entry, claim generation, insurance submission, payment posting, adjustments, and balance calculations.
Executed backend SQL data validation to ensure consistency between application interfaces and underlying databases, supporting accurate claim and financial data processing. Validated payer-specific business rules including claim edits, rejection handling, correction workflows, resubmissions, and insurance eligibility verification to ensure Medicaid and Medicare regulatory compliance. Verified financial accuracy by validating insurance payments, patient responsibility amounts, write-offs, adjustments, and remaining balances across billing cycles, collaborating with development and business teams to support UAT and improve application stability.
