On-Device AI & High-Performance Runtimes

Pioneered on-device AI architectures running open-source LLMs and image generation models natively on mobile hardware with zero cloud dependencies. Engineered dual-model Speculative Turbo decoding, modular dynamic GPU feature delivery (Vulkan/OpenCL/Metal), and defensive fork() crash isolation.

Kotlin Multiplatform (KMP) & Cross-Platform Parity

Architected production cross-platform solutions sharing game logic, MVI presentation stores, and offline-first persistence across Android, iOS, and Android TV, while preserving 100% native platform fidelity and ergonomics.

Modern Android & Adaptive UI

Expert in modern Android development patterns using Jetpack Compose and Compose Multiplatform, delivering responsive adaptive layouts across phones, foldables, tablets, and 10-foot TV experiences.

Digital Commerce & Hardware Integration

Led the development of scalable digital commerce platforms and low-latency hardware abstraction layers interfacing with 27+ POS peripherals, handling millions of transactions with high reliability.

📊 Impact & Results

  • Architected scalable mobile and multiplatform applications serving millions of users
  • Pioneered on-device LLM inference and local multimodal AI pipelines on consumer mobile hardware
  • Led teams of developers in implementing modern MVI and Clean Architecture patterns
  • Optimized performance across diverse Android devices, operating systems, and NDK backends
  • Mentored junior and mid-level developers in modern Android and Multiplatform practices
  • Contributed to developer communities through technical speaking and open-source contributions

AI Playground

  • Director & Lead Engineer | Kotlin Multiplatform, Compose Multiplatform, C++20 / NDK (llama.cpp v0.7.0), Google AI Edge LiteRT, Apple MLX, Vulkan/OpenCL/Metal, SQLDelight
  • An offline-first, on-device multimodal AI workstation for Android and iOS that turns mobile devices into self-contained inference engines. Executes local LLMs (GGUF, Safetensors, MediaPipe), synthesizes on-device diffusion images (Bonsai Image Ternary 4B / FLUX.2-klein), and parses 25+ document formats with zero cloud dependencies and 100% data privacy.
  • Features dual-model Speculative Turbo decoding (2x throughput speedup), crash-resilient fork() Vulkan driver isolation with SIGKILL watchdog, 100% offline activity ledger (SQLDelight v10), streaming mid-turn persistence, and full cross-platform voice parity.
