I would document ownership boundaries, version shared packages, define testing expectations, and use governance through design reviews and code reviews so reuse does not prevent project teams from moving quickly. Describe how you would improve accessibility for a highly interactive web experience. I would begin with an accessibility audit covering semantic HTML, keyboard navigation, focus management, form errors, color contrast, and screen-reader behavior. I would use ARIA only where native semantics are insufficient, test with automated tools and manual keyboard and screen-reader checks, then add accessibility criteria to component definitions and pull-request review standards. What techniques would you use to diagnose and improve rendering performance at scale in a React application? I would profile real user and lab performance metrics, inspect unnecessary renders with React tooling, measure bundle size, and identify expensive layout or network operations. Typical improvements include code splitting, route-level lazy loading, memoization where justified, virtualization for large lists, optimized images, stable state boundaries, and performance budgets in CI. How do you lead code reviews and mentor senior front-end engineers without becoming a delivery bottleneck? I make engineering standards explicit through documented conventions, component patterns, automated linting, tests, and clear review expectations. I prioritize reviews involving architecture, accessibility, security, and high-risk changes, while empowering senior engineers to review routine work and rotating ownership to build team capability. How would you introduce tools such as Claude Code or other coding assistants into an engineering workflow? I would start with approved use cases such as scaffolding, test generation, documentation, and refactoring assistance, while prohibiting sensitive data exposure and requiring human review for all generated code. I would measure impact through quality, cycle time, defect trends, and developer feedback, then refine team guidance and guardrails based on evidence.
