Second-year Electronics & Telecommunications student at VNUHCM – University of Science.
I build native, high-performance applications for Apple platforms and embedded hardware —
focused on privacy, offline-first design, and hardware–software co-design.
STM-FaceGuard — Dual-MCU Smart Lock
Real-time face recognition smart lock built on a STM32F411 + ESP32-S3/OV3660 dual-MCU architecture. Sub-0.2 s door-unlock latency via a custom UART protocol with packet checksum, watchdog recovery, and 24/7 security lockouts.
Pad Code AI — Code Editor & IDE
Write, compile, and manage code on iPhone and iPad with an Offline Compiler and Apple Intelligence integration — no internet required.
Pad Notes AI — Smart Note-Taking
Handwrite with Apple Pencil via PencilKit, convert to text with offline OCR, summarize with Apple Intelligence, record voice memos, sync via CloudKit, and chat with a Gemini AI assistant — all on device.
My NAS Manager — Synology DSM Client
Remotely manage your Synology NAS from iPhone and iPad. Real-time CPU/RAM/disk/S.M.A.R.T. monitoring, File Station, SSH terminal, HTTPS + 2FA authentication, and an offline Demo Mode.
PHTV — Precision Hybrid Typing Vietnamese
A native, offline Vietnamese input method for macOS 14+ built with Swift & C/C++. Smart Macro engine, Spell Checker, built-in Emoji Picker, and fully automated CI/CD via GitHub Actions, Sparkle, and Homebrew.
LunarV — Vietnamese Lunar Calendar
Cross-platform lunar calendar for iOS · iPadOS · macOS · visionOS built with SwiftUI + WidgetKit. Timezone-aware lunar conversion, home screen widgets, and traditional Vietnamese holiday reminders.
Lunar Block — 3D Space Puzzle
A high-fidelity 3D falling-block game built with SceneKit on a 14×20 playfield. Physics-driven block fracture, AVAudioEngine synthesized audio, layered haptics, and a circular gamepad. Runs on iPhone, iPad, Mac, and Vision Pro.
