Amorn Apichattanakul - Mobile Engineer with AI On-device Expertise and Flutter GDE

Mobile Engineering Excellence

As a Flutter GDE with 15+ years of experience, I've mastered the art of building exceptional mobile applications across Flutter, iOS, and Android platforms. My journey has taken me from native development to cross-platform solutions, always focusing on delivering high-quality, performant apps.

I've successfully integrated and optimized TensorFlow Lite models in production for features like face liveness detection, serving 3M+ users. My focus is on making AI work efficiently on mobile devices—optimizing inference speed, managing memory constraints, and maintaining the smooth, privacy-focused experience users expect.

Philosophy: Depth Over Breadth

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.

  • Deep Mobile Expertise: I don't claim to know everything, but I've dedicated 15+ years to mastering mobile development. I focus on complex challenges like memory management, app size optimization, and 120fps rendering rather than spreading myself thin across backend technologies.
  • Platform Mastery: My expertise spans Flutter, iOS (Swift/SwiftUI), and Android (Kotlin/Java). I understand the nuances of each platform and know when to use native solutions versus cross-platform approaches.
  • Quality & Performance: I ensure enterprise-grade reliability through comprehensive testing strategies including golden tests, widget tests, and integration tests. Performance optimization is at the core of everything I build.

"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."

Career Highlights

Flutter GDE

Recognized by Google as a Flutter Developer Expert since December 2022. Actively contributing to the Flutter community through public speaking and technical blogging.

Staff Engineer @ KBTG

Leading a team of 12 mobile engineers on a high-security financial app serving 3 million users. Building with Flutter, iOS, and Android while integrating on-device AI capabilities using TensorFlow Lite.

15+ Years Mobile Expertise

Deep expertise in Flutter, iOS, and Android development. Mastered mobile internals including memory optimization, native platform integrations, and performance profiling for enterprise-scale applications.

Featured Work

On-Device Liveness Detection @ KBTG

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 led a 2-year initiative to integrate and optimize a TensorFlow Lite face liveness model into 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 coordinated between data science (model training), mobile engineering (integration), and security (compliance) teams to deliver a seamless production solution.

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.

App Performance Optimization @ KBTG

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.
