Hi there! 👋 I'm Tuan

🚀 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
