Influence and evolve our architecture: propose and lead initiatives to decompose monoliths, build shared libraries and frameworks, improve modularization, enable reuse across Android, iOS, and Web; evaluate new Android platform capabilities (e.g., new OS releases, device types, form factors, architectures) and lead their adoption. You have been a technical leader (not just an individual contributor): you've influenced roadmap decisions, contributed to multi-team initiatives, mentored/led developers, driven culture/process improvements, and interfaced with senior developer/product leadership.
