Perform end-to-end testing of backend data pipelines processing cryptocurrency market data; validate data ingestion, transformation, aggregation, and delivery flows; lead API testing for internal backend services; identify inconsistencies in data aggregation logic to prevent incorrect financial data reaching end users; utilize Jenkins-based CI/CD pipelines for build validation and release readiness; access remote environments via SSH to troubleshoot backend processes and inspect logs; own QA activities from ticket analysis and test planning to release validation and production checks; reduce manual verification by creating validation scripts and workflows for repetitive backend and data checks; collaborate with developers, product stakeholders, and data teams to clarify requirements and improve test coverage.

Tested 8+ interconnected microservices in a large-scale healthcare system used by 52,000+ staff and 320+ locations. Reduced release regression time by 70%+ through automated tests using Kotlin. Performed deep API and database validation to ensure data consistency across backend services and integration points. Validated complex backend workflows, service interactions, business rules, and data synchronization. Used SQL and backend checks to verify data accuracy and support root cause analysis. Accessed remote servers via SSH to validate backend uploads, scripts, runners, and logs. Collaborated with cross-functional US-based teams to clarify requirements and improve defect detection and acceptance criteria. Supported release validation activities, regression planning, smoke testing, and production readiness checks.

Tested a global event platform during migration from a legacy system to a new architecture, helping ensure a stable production transition. Designed and executed test scenarios for new features from scratch, covering functional, API, regression, acceptance, and release testing. Performed API testing for core platform functionality, validating business logic, backend responses, and integration behavior. Implemented and maintained Cypress-based UI automated tests, contributing to growing regression automation coverage. Conducted data migration validation to ensure data integrity and consistency between legacy and new systems. Created test plans, regression checklists, release validation scenarios, and production verification steps; presented testing progress and results to stakeholders.
