🚀 About Me

I'm an IoT Expert and Embedded Systems Engineer from Vietnam, specializing in building embedded systems from the ground up. With deep expertise in ESP8266/ESP32 ecosystems, I've written most networking protocols from scratch for resource-constrained embedded devices.

I'm a core contributor to Espressif's official ESP-IDF framework, where I developed the base protocol stack that powers millions of IoT devices worldwide.

🎯 Core Expertise

📡 Protocol Implementation from Scratch

I've implemented the following protocols from scratch for embedded systems, optimized for memory-constrained environments:

Protocol Description Used In
MQTT Lightweight pub/sub messaging protocol ESP-IDF, esp_mqtt
HTTP/HTTPS Full HTTP client with chunked encoding, auth, redirects ESP-IDF esp_http_client
WebSocket Real-time bidirectional communication ESP-IDF, esp_mqtt
DLNA/UPnP Digital Living Network Alliance for media streaming ESP-ADF
AirPlay Apple's wireless streaming protocol Custom projects
SIP Session Initiation Protocol for VoIP Custom projects

🎵 Audio Processing for Embedded

Deep expertise in embedded audio systems:

  • I2S driver development with APLL clock support
  • Audio codec integration (ES8388, AC101, etc.)
  • Real-time audio streaming and processing
  • Text-to-Speech integration (AWS Polly, Google TTS)
  • SAM (Software Automatic Mouth) implementation

🔧 ESP-IDF Base Protocol Contributions

As a core contributor to Espressif's ESP-IDF, I built foundational components:

  • Transport Layer - TCP/SSL/WebSocket abstraction
  • HTTP Client - esp_http_client component
  • MQTT Client - Official esp-mqtt component
  • I2S Driver - Audio I/O with DMA support
  • HTTP Server - Request/response handling
