Flutter Developer

Part of a 10+ developer team across the US and EU on Pro2Col Health, Herbalife's production health and wellness app.

Built a region-aware privacy consent system for EU, Canada and Quebec, with banners, dialogs, and SMS, marketing and coach consent. Integrated with Adobe MobileCore to block analytics until consent is given.
Designed a QA automation ID system (800+ IDs) with two custom lint rules that fail the build on hardcoded or duplicate IDs. Fixed locale-dependent IDs so UI automation stays stable across all supported languages.

Contributed to the nutrition tracking rebrand: food search and add/edit screens, recipes, barcode scanner and press-and-hold voice input.
