Design, enhance and institutionalize test engineering procedures and standards; define, implement and report on test metrics to measure application quality and delivery risk.
Champion shift-left testing practices (TDD/BDD, white-box/gray-box testing, code coverage, static analysis, service virtualization) to detect defects earlier and improve code quality.
Lead and manage complex projects and subprojects: create project plans, assign tasks, estimate effort, manage QA activities to plan and coordinate cross-functional teams in onsite-offshore delivery models.
Drive automation strategy and implementation across Java and TypeScript stacks; integrate automated tests (unit, API, end-to-end, regression, smoke) into CI/CD pipelines and pipeline gating.
Own performance, load and scalability testing initiatives and perform holistic system-level analysis to identify bottlenecks and remediation actions.
Establish and manage test data management, environment virtualization and security testing initiatives to support reliable and repeatable testing across sprints.
Lead defect triage processes and collaborate with development and product teams to prioritize and resolve issues.
Provide expert guidance on testing systems, processes and methodologies to clients, IT management and project teams throughout the full project lifecycle.
Mentor and coach QA engineers; build team capabilities, promote knowledge sharing and improve technical depth across teams.
