About Nikitha Dubbaka

I am a results-driven Software Quality Assurance Analyst with 4 years of experience in manual and automation testing, with a focus on the healthcare domain. I consistently deliver high-quality solutions through test design, API testing, automation frameworks, defect management, and UAT collaboration.I have hands-on expertise in functional, regression, integration, smoke, and API testing across web, backend, and mainframe systems. I specialize in Selenium WebDriver (Java and Python), TOSCA, Postman, SoapUI, qTest, TestNG, and Maven. I build scalable test automation frameworks that improve efficiency and reduce manual efforts.At Cognizant, I performed end-to-end testing for CSC (Mainframe Application) and validated healthcare workflows aligned with FHIR profiles, HL7 standards, and US Core profiles. I led API testing and FHIR validation to ensure healthcare compliance and accurate data exchange.I automated over test cases using TOSCA, reducing manual testing by 70% and improving regression cycles for the Availity Healthcare Portal. I implemented AI-based batch scheduling to reduce test execution time by 20% and piloted AI-driven test case optimization to minimize redundancy.I am skilled in test execution, defect tracking, test data management, and consistently delivered high-priority user stories with zero defect leakage, contributing to a 15% improvement in team delivery efficiency. I independently handled user stories from requirement analysis to defect closure and supported UAT validations.I mentored new team members through Knowledge Transfer (KT) sessions, improving onboarding and productivity. I am passionate about continuous learning and expanding automation skills using Selenium with Java and C# to build scalable frameworks.I have strong healthcare expertise, including FHIR, HL7, claims processing, and authorization workflows. I thrive in Agile teams and am eager to contribute to quality engineering and healthcare projects.
