CHETHANA S REDDY

• Drove end-to-end QA for payments features, improving production stability and reducing payment flow defects by 35% through functional testing on the front end on Android and iOS devices, API validation, integration testing, and systematic regression.
• Collaborated with business owners to gather requirements, and scripted the user acceptance stories.
• Scripted and maintained project documentation, including test plans, test cases, and defect reports, to facilitate knowledge transfer among team members.
• Increased test coverage from approximately 60% to 80% across critical user journeys by adding test designs, BDD scenarios, and data-driven test case prioritization in Xray.
• Supported successful product launches by rigorously testing activities and functionalities in different environments and configurations, such as Dev, Test, UAT, Preprod, and Prod.
• Implemented JMeter performance test suites (API and UI flows) to validate peak traffic on the app, identified bottlenecks that reduced the 95th percentile latency by 20% after CPU and latency adjustments.
• Established Jenkins/GitLab CI pipelines to run nightly API, performance test suites, and automation suites that improved early defect discovery, cutting UAT critical defects by 25%.
• Improved release confidence by formalizing sanity and upgrade testing on UAT/PROD, decreasing post-release hotfixes by approximately 15% over two quarters.

Key Responsibilities:

• Frontend functional testing and exploratory testing on the web and mobile (iOS and Android).
• Backend API validation via Postman, Swagger, and Charles; data verification on the backend.
• Test planning, execution, defect triage, and reporting in Agile ceremonies (planning, review, retrospectives).
• User Acceptance Testing support and post-release verification of features on the app across all the platforms.
• Performance test scripting for API and UI features for payments and other features of the app.

E-commerce Platform (Web, APIs, Data Pipelines)

• Owned functional, regression, integration, and end-to-end testing for multiple releases, contributing to a 98% on-time release rate.
• Reduced defect leakage to production by 28% via expanded regression coverage, and earlier API contract testing.
• Automated critical web journeys with Selenium and Cucumber, saving approximately 25% of manual effort per release cycle.
• Built API load and stress tests in JMeter; validated target QPS and resource utilization, enabling performance tuning that improved throughput by 15% under peak.
• Designed and executed API automation in Postman and service-level validations; established collections and environments for repeatable runs.
• Validated batch processes and data flows across Hive, MongoDB, and SQL; detected and prevented multiple data quality regressions before production.
• Led peer test case reviews and established quality gates; produced QA metrics dashboards for stakeholders, improving transparency and decision-making.
• Mentored interns and trainees on QA fundamentals, tooling, and project workflows.
• Coordinated cross-functional testing with product managers, BAs, devs, and support teams to refine requirements and acceptance criteria.
• Authored release QA reports summarizing coverage, defect density, and risk assessment.

• I researched chatbots and NLP, and developed a Python chatbot and a web application frontend using Python and MySQL.
• Evaluated system requirements to create strategic test approaches tailored to various project needs.
• Facilitated bug tracking and resolution through detailed documentation and communication with developers.
