What You’ll Build

• Spin up environments with specific feature flag combinations using infrastructure‑as‑code
• Load test configurations with realistic customer data volumes in containerized environments
• Run comprehensive test suites across multiple environment configurations with automated benchmarking
• Generate detailed performance and reliability reports across different cloud environments
• Automatically detect and flag regressions in diverse usage scenarios
• Scale testing infrastructure to accommodate our growing customer base
