At NDP Health, I validate HIPAA-sensitive document ingestion and PHI/PII handling in RCM pipelines. I test REST API responses and AWS microservice integrations for a GPT-based RAG system, using LLMs to expand test scenarios and edge-case coverage.
At Insignia Group, I owned testing for VISA Direct and MS Dynamics 365 payment integrations, including APIs and financial reports. I resolved a critical production transaction defect and reduced regression testing time by 30% through migration from Jira Zephyr to Allure TestOps.
At Colnect, I built the QA function from scratch, defining KPIs that reduced development task downtime from 7+ days to 2. Earlier, I created Python/Pytest integration suites and API automation at Tochka Bank and VTB Bank, and established QA processes at King Bird Studio.
