The content represents our development journey and architectural decisions. Code examples are simplified illustrations and may not reflect the exact production implementation. The Biometric Challenge Caroline had a question that changed everything: “What if we could track heart rate during pressure points?” I looked up from my keyboard. “You mean correlate biometric data with match events?” “Exactly,” she said. “We already track every shot, every score change. If we add heart rate and movement data, we could see exactly when players get stressed.” Claude liked the idea: “Biometric data would let you detect fatigue patterns, recovery rates, momentum shifts—all based on actual physiology, not just scores.” We needed a system that could handle high-frequency data (up to 50Hz for gyroscopes), stream it in real-time from wearables, and correlate it with our existing event sourcing system. ...
