Staff Mobile Engineer
& On-Device AI Expert

Challenge: Scaling mobile development across 25+ squads within a 3,000-engineer organization while maintaining architectural consistency, security, and performance for a financial super-app serving a massive user base.

My Role: Serving as the Head of Mobile Guild, I define the "Flutter-Native Hybrid Strategy" and technical standards for the entire organization. I act as the primary technical authority, advising on complex architectural decisions (when to use Flutter vs Native) and establishing the CI/CD and observability infrastructure (Firebase/Analytics) that enables data-driven product agility.

Impact: Successfully standardized coding practices, reduced technical debt, and implemented a "Zero Downtime" strategy for various platform shifts (e.g., Privacy Manifests), ensuring stability for mission-critical financial services.

Challenge: To enhance security for our massive user base in a high-security financial application, we needed to implement real-time face liveness detection that could run entirely on-device without compromising user privacy or app performance.

My Role: As Staff Engineer, I have been leading an ongoing initiative since 2022 to integrate and continuously optimize a LiteRT (TensorFlow Lite) face liveness model in our production Flutter app. I architected native iOS and Android bridges using platform channels, optimized model inference performance (reducing latency by 40%, memory usage by 30%) across different device capabilities, and coordinate between data science (model training), mobile engineering (integration), and security (compliance) teams to deliver seamless production improvements.

Impact: Successfully deployed on-device AI that processes sensitive biometric data locally, eliminating server round-trips and maintaining user privacy while achieving real-time detection accuracy that met our security requirements across millions of daily authentications.

Challenge: Our financial app serving millions of customers needed to maintain enterprise-grade performance while handling increasing feature complexity, strict security requirements, and variable network conditions across diverse device capabilities.

My Role: As Staff Engineer leading platform engineering, I architected and implemented comprehensive performance optimizations including intelligent API strategies, multi-layer caching, offline-first architecture, and server load reduction—all while maintaining strict security compliance for financial transactions.

Impact: Reduced app launch time by 40%, decreased API calls by 60% through smart caching, improved offline functionality for critical user flows, and significantly reduced server costs while maintaining zero security incidents.
