duplication

// Context

Three products each re-implemented step and workout sync against Google Fit, Health Connect and Huawei Health — duplicated code, inconsistent behaviour and fragile Huawei support.

// What I built

+Designed one Health SDK exposing a single Flow-based API over all providers

+Added fallback logic that picks the first available provider and retries

+Built a unified permission manager to remove per-app boilerplate

+Wrote an integration guide so teams adopt it in hours
