I'm an Embedded & IoT Engineer from Ho Chi Minh City University of Technology - Vietnam National University (HCMUT - VNU), dedicated to building seamless and optimized systems.
-
Industrial Machinery Maintenance Monitoring System (IIoT Maintenance System)
- Hardware: Designed a data acquisition system using ESP32-WROOM-32U with MPU6050 (3-axis vibration), AHT30 (temperature & humidity), and INA219 sensors.
- Analysis: Integrated FFT algorithm to distinguish vibration sources and send alerts via Google SMTP.
- Dashboard: Built on DevExpress WinForms platform, aligned with IIoT workflow requirements.
-
Factory Employee Tracking System with Edge AI & YOLOv8
- Computer Vision: Implemented YOLOv8 and ByteTrack for zone-based personnel identity assignment, dynamically tracking work time, away states, and returns without relying on facial recognition.
- Optimization: Exported and deployed neural networks using the OpenVINO toolkit to maximize real-time inference speed and FPS on local Intel CPU architecture.
- Software Pipeline: Developed an interactive OpenCV application for custom multi-zone drawing, automated CSV event logging for DevExpress dashboard integration, and built a custom fine-tuning pipeline using Roboflow and Google Colab.
-
Air Quality Prediction System with Edge AI
- Model: Trained a Neural Network (2 hidden layers, ReLU activation) for nonlinear regression on PM2.5 and toxic gas data.
- Deployment: Deployed model on CK-RA6M5 (RENESAS) kit; data forwarded to ESP32 via UART3 and pushed to a dashboard through WebSocket.
- Debugging: Used J-Link driver on e2 Studio with breakpoints and Expressions monitoring.
-
Handheld Game Console — BKonsole
- Hardware: Designed PCB in KiCad, integrating LCD 1602, 8x8 LED Matrix driven by MAX7219, and 4 physical buttons on ATmega324P.
- Firmware: Programmed in Embedded C with interrupt handling to implement Snake and Pickleball game logic.
- 🐋 Containerization: Using Docker to orchestrate IoT services (MQTT, Node-RED) on Ubuntu Linux Gateways.
- 🐧 System Optimization: Deep diving into Linux Kernel and resource management for Embedded Linux.
- 🖥️ Desktop Apps: Utilizing DevExpress to build professional monitoring and management UIs.
- ⚡ Advanced PCB: Mastering multi-layer PCB design and EMI/EMC protection in KiCad.
- Model compression techniques (Quantization, Pruning) for low-power hardware.
- Industrial IoT security standards (TLS/SSL, Secure Boot) for embedded devices.
I'm an introvert who enjoys cooking and staying active through sports like badminton, swimming, and gym workouts. ^^
