• Improve performance and reliability of large pipelines through indexing, sharding, caching and query optimization.
• Build AI-assisted surfaces on top of existing AI capabilities: context assembly, cost/latency budgets, graceful degradation.
• Ship end-to-end when needed—including Vue UI changes—without blocking cross-functional handoffs.
• Instrument the system: logs, metrics, traces, and SLOs for production visibility.
