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.

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 |
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
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
