Staff Mobile Engineer specializing in Flutter, iOS, Android, and On-Device AI
As a Flutter GDE with 15+ years of experience, I've mastered building exceptional mobile applications across Flutter, iOS, and Android platforms. My journey from Environmental Engineering to ActionScript development, then to mobile platforms, and now to on-device AI demonstrates continuous learning while building cumulative expertise—each phase added depth to my understanding of building user-facing applications.
I've successfully integrated and optimized LiteRT (TensorFlow Lite) models in production on-device AI mobile applications for features like face liveness detection, serving 3M+ users. I'm actively studying and expanding my expertise in on-device AI mobile technologies—focusing on optimizing inference speed, managing memory constraints, and maintaining the smooth, privacy-focused experience users expect.
The mobile ecosystem is deceptively deep. I believe that to truly master the nuances of performance and UX, one cannot afford to be a generalist.
"I'm not just a mobile developer—I'm an expert who understands mobile platforms deeply and delivers experiences that users love and businesses depend on."
Recognized by Google as a Flutter Developer Expert since December 2022. Actively contributing to the Flutter community through public speaking and technical blogging.
Leading a team of 12 engineers on a high-security financial app serving 3 million users. Building with Flutter, iOS, and Android, with proven on-device AI mobile experience integrating LiteRT (TensorFlow Lite) models in production.
Deep expertise in Flutter, iOS, and Android development. Mastered mobile internals including memory optimization, native platform integrations, and performance profiling for enterprise-scale applications.
Challenge: To enhance security for 3M+ users 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 3M+ users 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.
Since becoming a GDE in December 2022, I've been actively contributing to the Flutter community through technical articles on benamorn.medium.com and speaking at tech conferences across Southeast Asia.
My talks cover Flutter development, mobile architecture, platform integrations, and recently, on-device AI implementation—sharing practical insights from real-world production experience.
