WebRTC platform development
End-to-end engineering: signaling, media negotiation, browser compatibility and mobile support.
Services
Real-Time Communication Engineering
The hardest case in web engineering: WebRTC media, SFUs, SIP interop and live captioning under real-world network conditions — engineered by the team behind Sonar, a video-consultation platform used in the German banking sector.
Evidence
What this domain delivers
What we have shipped in this domain
- WebRTC and media-pipeline engineering inside a long-term platform engagement in the German banking sector — video consultation running in production, including recording and queue management.
- Kurento operation and migration in production, plus live in-call captioning and translation in 15 languages, integrated directly into the media pipeline.
What we offer as capability
- LiveKit builds including SIP/telephony interop — hands-on build experience across signalling, media and telephony bridging.
- Kurento-to-modern-SFU migration: a worked method for mapping recording, RTP/SIP bridging and in-pipeline processing onto LiveKit- or mediasoup-based architectures.
- Computer vision in the live media path, fed frame by frame from the pipeline we already operate.
Capabilities
What we do
Modern SFU engineering
We design and build on current media stacks: LiveKit (including SIP/telephony interop, which we have built hands-on) and mediasoup-class SFUs. Stack selection is driven by your requirements, not by habit.
Kurento operation and migration
Few teams still carry deep, production-grade Kurento expertise; we do. We operate legacy Kurento estates and migrate them to modern stacks (LiveKit, mediasoup) while preserving recording, compliance and in-pipeline processing features.
Video consultation platforms
Advisor-to-customer video for regulated industries, including recording, waiting-room and queue management, built through our long-term work on a video-consultation platform for German banks.
Live captioning and translation in calls
Real-time multilingual subtitles in 15 languages, including Indian languages, powered by Whisper ASR integrated directly into the media pipeline. The model work behind it is described under AI & model engineering.
AI in the video path
Computer-vision analysis of live video streams, such as our AI damage analysis for insurance video calls.

Method
How we work
-
Architecture first.
Media topology, codec strategy, and scaling model are decided before code is written — retrofitting these is expensive.
-
Modern stack, proven patterns.
New builds start from current SFU architecture; the signaling, recording and media-handling patterns come from years of operating a production video-consultation platform.
-
Test like the network is hostile.
Packet loss, NAT traversal, low bandwidth and browser quirks are part of our test matrix, not surprises in production.
-
Operate what we build.
We offer ongoing operation and monitoring — real-time media is a living system, not a delivered artifact.
FAQ
Frequently asked questions
Can you build a video-consultation platform for a bank or insurer?
Yes. That is our deepest track record: we are the long-term engineering partner for Sonar, a video-consultation platform whose users include German banks. We understand the data-protection and reliability expectations of regulated financial institutions. The sector view is on our banking & insurance page.
Which media server do you recommend — LiveKit, mediasoup or Kurento?
For most new platforms in 2026 we start from a modern SFU: LiveKit when you want a batteries-included, scalable stack with SDKs and SIP interop, mediasoup when you need a lean, high-performance SFU core. Kurento remains the right niche answer when heavy server-side media processing is the actual requirement. We have built with LiveKit, and our deepest production operating experience is in media pipelines — so the recommendation comes from running these things, not from a comparison chart.
We run a legacy Kurento platform — can you help?
Yes, in both directions. We can operate and stabilize an existing Kurento estate (a skill that is getting hard to hire for), and we plan and execute migrations to modern stacks — mapping recording, RTP/SIP bridging and in-pipeline processing onto LiveKit- or mediasoup-based architectures without losing the features that made you choose Kurento originally.
Do you support live captions and translation inside video calls?
Yes. We have built live multilingual captioning and translation for video consultations in 15 languages, including Indian languages, using Whisper ASR — running self-hosted, so audio never leaves the client's infrastructure.
Does "real-time communication" mean video only?
No. It covers the whole real-time surface we engineer: video and audio over WebRTC, telephony interop via SIP, live captioning and translation in the media path, recording and queue management. Video consultation is the application we have taken furthest in production.
Can AI analyze the video stream itself, not just the audio?
Yes. We have built AI damage analysis on live insurance video calls using a self-hosted open vision-language model, feeding frames from the media pipeline to the model in real time.
Do you also operate the platform after launch?
Yes. Long-term operation is our preferred engagement model — we run CI/CD, containerized deployment, and monitoring for the platforms we build. See our security & data stewardship page for how operational access is scoped.
