About this gig

Need live video calling, live streaming, or real-time audio in your

app? I build it right the first time.


With 14+ years in real-time media systems deep WebRTC, FFmpeg, and

streaming expertise combined with full stack skills, I integrate

reliable video/audio features most developers struggle to get right.


WHAT I BUILD:

- One-on-one or group video calling (WebRTC)

- Live streaming (RTMP, HLS, low latency)

- Screen sharing and recording

- Real-time audio/video for social, dating, education, telehealth apps

- IP camera / RTSP feed integration for web playback


WHY THIS IS HARD:

Streaming has real traps sync issues, latency, NAT traversal,

scaling media servers. Most devs just plug in a third-party SDK,

which breaks under real conditions. I build at the protocol level.


TECH STACK:

WebRTC, FFmpeg, SRS, Mediasoup, LiveKit, Node.js, React, C/C++


HOW IT WORKS:

1. Tell me what you're building and your current setup

2. I recommend the right architecture

3. I build, test, and integrate the feature

4. You get working code plus scaling guidance


Message me with your use case before ordering.

I'm a software engineer with 14+ years of experience across backend, real-time media, and full stack development. I specialize in real-time video/audio systems, media servers, and embedded video pipelines — with deep expertise in WebRTC, FFmpeg, and streaming protocols across Linux, Android, and Windows. More recently, I've been using AI tools (Claude Code, Cursor) to rapidly build full stack MVPs, combining senior-level judgment with AI-accelerated speed. Whether you need a robust streaming solution or a fast, well-architected MVP, I bring deep experience to get it right the first time.
