About Me

Engineering Leadership & Background

Phnom Penh, Cambodia · UTC+7

I'm a Mobile Tech Lead & Software Engineer based in Phnom Penh, Cambodia. Over the past 4+ years, I've designed and shipped mobile applications used by tens of thousands of users across Southeast Asia, specializing in Flutter, Dart, real-time WebRTC, and Node.js.

Currently, I direct mobile development at GateKhmer.ai (Codingate Technology), guiding engineering teams through complex product lifecycles — from initial architecture and custom UI design to store compliance and backend integrations.

Beyond day-to-day product leadership, I maintain open-source packages on pub.dev, publish technical breakdowns on Bakong KHQR and Mediasoup SFU architectures, and help development teams avoid costly store rejections and architectural missteps.

Production Architecture

Mediasoup SFU • Real-Time Audio & Video Infrastructure

Production WebRTC architecture built for GateKhmer.ai video & audio consultations, replacing third-party SaaS with a self-hosted SFU cluster.

< 180ms End-to-End Latency
65% Bandwidth Savings vs Mesh
Opus 48kHz Adaptive Audio Codec
PRODUCER Flutter Mobile Client flutter_webrtc • Camera/Mic capture
WSS Signaling + DTLS-SRTP
SFU CLUSTER Mediasoup C++ Workers Selective packet forwarding • Zero transcode
Adaptive Simulcast Downlink
CONSUMERS Multi-Party Participants Dynamic bitrate • Network loss resilience
Selective Forwarding vs. Mesh: Instead of N×(N-1) uplink streams choking mobile bandwidth, each mobile peer produces a single encrypted stream, forward-routed at C++ worker speed.
Simulcast & Dynamic Degradation: Multi-layer spatial video encoding (1080p / 720p / 360p) with seamless layer downgrading when mobile peers experience cellular jitter.
NAT Traversal & ICE Restarts: Co-located STUN/TURN fallback ensuring high connection success across strict enterprise and cellular firewalls.
