Why MetaDesign
LiveKit experts who ship production voice AI.
Hire LiveKit developers — Agents, rooms, SIP — real-time infrastructure done right.
01
Ultra-Low Latency
Our real-time voice AI infrastructure built on LiveKit's WebRTC stack delivers sub-200ms latency — enabling natural, real-time conversations between users and AI agents.
02
AI Agent Framework
We specialise in LiveKit AI agent development using the Agents framework — server-side Python/Node agents that listen, think, and speak in real time with STT, LLM, and TTS pipelines.
03
Self-Hosted or Cloud
As a trusted LiveKit integration partner, we deploy on your own infrastructure for data sovereignty, or use LiveKit Cloud for managed scalability — architected for both.
AI Voice Agents
Custom voice AI solutions with LiveKit — real-time voice AI agents that handle customer calls with natural conversation flow and sub-second response times.
Video Conferencing
Custom video conferencing with AI features — transcription, translation, and intelligent meeting summaries.
Live Streaming
Interactive live streaming with multimodal AI agent development — real-time audience participation and AI-powered moderation.
Contact Centre AI
AI-powered contact centre with low-latency WebRTC AI integration replacing legacy telephony systems.
Our approach
Five stages, paired end-to-end.
Predictable delivery. No black-box sprints.
01
Architect
Design real-time infrastructure — rooms, participants, tracks, and AI agent topology.
02
Build
Develop LiveKit agents with STT/LLM/TTS pipelines and custom business logic.
03
Integrate
Connect to your CRM, knowledge base, and telephony systems via SIP.
04
Deploy
Production deployment with auto-scaling, monitoring, and failover.
05
Optimise
Latency tuning, cost optimisation, and continuous agent improvement.
Customer value
Six places it pays back in the first sprint.
Real outcomes our clients report within the first engagement cycle.
Faster time-to-market
Production-ready teams that ship from week one — no ramp-up lag.
Reduced technical risk
Architecture reviews, code audits, and security scans baked into every sprint.
Measurable velocity
Cycle time, PR throughput, and defect density tracked from day one.
Cost predictability
Fixed-price or capped T&M — no surprise invoices, ever.
Continuous improvement
Retros, post-mortems, and process refinement every sprint.

LiveKit is an open-source, real-time voice AI infrastructure purpose-built for AI applications. Unlike Twilio, it offers self-hosting, an AI Agents framework, and ultra-low latency — ideal for custom voice AI solutions with LiveKit.
Yes. When you hire LiveKit developers from MDS, we deploy clusters handling 10,000+ concurrent sessions with automatic load balancing and geographic distribution.
Yes. LiveKit supports SIP trunking — your AI agents can receive and make real phone calls via PSTN while running on modern WebRTC infrastructure.
Yes. Self-hosted LiveKit with encryption, access controls, and audit logging meets HIPAA requirements. Our dedicated LiveKit support & maintenance team deploys compliant configurations for healthcare clients.
LiveKit utilizes a highly optimized WebRTC architecture and a globally distributed edge network, which minimizes audio transit times and allows for real-time, conversational Voice AI without noticeable lag.
Absolutely. You can hire our experienced LiveKit developers on a staff augmentation basis to seamlessly integrate with your in-house engineering team and accelerate your real-time voice AI projects.
We enforce end-to-end encryption via WebRTC, secure token-based authentication for room access, and strict data retention policies to ensure your real-time voice AI infrastructure is fully compliant and secure.
Common use cases include autonomous AI customer support agents, real-time language translation over audio, interactive AI tutors, and sophisticated multimodal AI avatars.
Yes, by integrating low-latency transcription and translation LLMs into the LiveKit pipeline, the AI agent can seamlessly listen, translate, and respond in multiple languages.
We utilize LiveKit's adaptive bitrate streaming and intelligent packet loss concealment algorithms to ensure the voice AI interaction remains stable and intelligible even on poor network connections.
