• Lead the AI-assisted migration approach, designing reusable AI-automation paradigms such as agent swarms, automated dual-repo synchronization, and continuous improvement of translation efficiency using automated feedback loops.
• Architect a paved-road native framework in Swift and Kotlin that sets the architectural bar across teams, unlocking the ability for a single mobile contributor to be productive in both iOS and Android codebases simultaneously.
• Drive organizational readiness as a trusted cross-functional partner with product, design, and engineering leadership, resolving cross-team blockers, de-escalating conflict during the dual-app straddle period, and holding peer leaders to a high bar so their patterns spread across teams.
• Mentor L5-L6 engineers, develop the technical leadership pipeline for native mobile, and recruit actively through reputation, ensuring the team excels in your absence and your successor is developing.
• Become a leader throughout the entire mobile community at Coinbase, defining best practices and fostering connection and support between all mobile engineers.

• Track record of owning outcomes spanning 2-3+ teams that drive business impact, including multi-phase platform migrations or rewrites at scale where you shaped strategy and made trade-offs that raised ROI across teams.
• Deep mobile performance expertise across iOS and Android, including cold start optimization, frame stability, scroll jank elimination, and device-tier profiling, with experience setting the architectural bar and defining ownership boundaries other teams build against.
• Proven influence without authority at senior levels, with experience changing the technical direction of teams outside your own, securing leadership alignment on ambiguous high-stakes decisions, and resolving cross-team blockers using all tools at your disposal.
• Experience designing AI-native engineering workflows adopted across teams, including LLM-driven code generation, agent-based automation, or reusable automation patterns that re-implement existing workflows.
