   • Architected a hybrid deterministic + LLM system with structured outputs, validation gates, evidence-backed constraints, on-device intent routing, and offline fallbacks, reducing AI-coach execution from up to 9 model calls to a 4-call budget per question while improving privacy and failure handling.
   • Built a 4- to 12-week adaptive training-plan engine with automated progression, constraint validation, retry-on-violation, and deterministic fallback, and validated generation through an 82/82 live-AI run, ~3,945-case test matrix, adversarial testing, and 6 XCUITest flows.
   • Engineered HealthKit-based Recovery, Training Readiness, Strain, and Stress systems using personalized baselines, plus adaptive nutrition, menstrual-cycle-aware guidance, and Weekly Intelligence. Replaced an unsourced calorie model with 2024 Compendium MET values, correcting a 6-hour idle-workout estimate from 1,260 kcal to 53 kcal.
   • Built the Apple Watch companion with live workout execution, heart-rate zones, motion-based rep detection, and effort scoring, and integrated StoreKit 2, iCloud sync, Firebase Analytics, Realtime Database, Crashlytics, and App Check for subscriptions, synchronization, telemetry, crash diagnostics, and app integrity.
   • Expanded ZEALO beyond Apple Watch by integrating WHOOP, Oura, Fitbit, and Garmin, normalizing cross-device health, activity, sleep, heart-rate, and recovery signals into a unified intelligence layer for readiness, training, recovery, and personalized recommendations.
   • Built and launched Tech Signal, aggregating 30+ developer sources with cache-first loading, personalized ranking, trend detection, and on-device summarization using Apple’s Natural Language framework, with zero third-party runtime dependencies.
