Lahore, Pakistan - 10:43 pm local time
I build enterprise-grade real-time systems, 𝐖𝐞𝐛𝐑𝐓𝐂 / 𝐋𝐢𝐯𝐞𝐊𝐢𝐭, 𝐒𝐈𝐏/𝐕𝐨𝐈𝐏 𝐭𝐞𝐥𝐞𝐩𝐡𝐨𝐧𝐲, and 𝐕𝐨𝐢𝐜𝐞 𝐀𝐈 (STT/TTS + conversational AI). If you're dealing with 𝐥𝐚𝐭𝐞𝐧𝐜𝐲, 𝐜𝐚𝐥𝐥 𝐝𝐫𝐨𝐩𝐬, 𝐍𝐀𝐓/𝐓𝐔𝐑𝐍 𝐢𝐬𝐬𝐮𝐞𝐬, 𝐫𝐞𝐜𝐨𝐫𝐝𝐢𝐧𝐠 𝐟𝐚𝐢𝐥𝐮𝐫𝐞𝐬, 𝐬𝐜𝐚𝐥𝐢𝐧𝐠 𝐩𝐫𝐨𝐛𝐥𝐞𝐦𝐬, or 𝐕𝐨𝐢𝐜𝐞 𝐀𝐈 𝐢𝐧𝐭𝐞𝐠𝐫𝐚𝐭𝐢𝐨𝐧, I can help you deliver a stable solution end-to-end.
I'm 𝐓𝐨𝐩 𝐑𝐚𝐭𝐞𝐝 𝐏𝐥𝐮𝐬 on Upwork with strong long-term delivery history, and I focus on what clients actually care about, 𝐫𝐞𝐥𝐢𝐚𝐛𝐢𝐥𝐢𝐭𝐲, 𝐬𝐜𝐚𝐥𝐚𝐛𝐢𝐥𝐢𝐭𝐲, and 𝐦𝐞𝐚𝐬𝐮𝐫𝐚𝐛𝐥𝐞 𝐩𝐞𝐫𝐟𝐨𝐫𝐦𝐚𝐧𝐜𝐞 (join time, RTT, jitter, packet loss, concurrency, CPU/bandwidth cost). I'm also an inventor on a 𝐠𝐫𝐚𝐧𝐭𝐞𝐝 𝐔𝐒 𝐩𝐚𝐭𝐞𝐧𝐭 (𝟏𝟐,𝟒𝟓𝟐,𝟑𝟏𝟕) in teleconferencing/real-time communication, so RTC is not just "a feature" for me; it's the core.
𝐖𝐡𝐚𝐭 𝐈 𝐝𝐨 𝐛𝐞𝐬𝐭
✅ 𝐖𝐞𝐛𝐑𝐓𝐂 / 𝐋𝐢𝐯𝐞𝐊𝐢𝐭 (𝐥𝐨𝐰‑𝐥𝐚𝐭𝐞𝐧𝐜𝐲 𝐚𝐮𝐝𝐢𝐨/𝐯𝐢𝐝𝐞𝐨 + 𝐬𝐜𝐚𝐥𝐢𝐧𝐠)
• LiveKit architecture (self-hosted) + production hardening
• SFU scaling strategy (regions, routing, concurrency planning)
• TURN/STUN/ICE reliability for strict NAT / enterprise networks
• Performance tuning: jitter, packet loss, bitrate adaptation, simulcast/SVC strategy
• Recording/egress pipelines + media routing + stream health monitoring
✅ 𝐓𝐞𝐥𝐞𝐩𝐡𝐨𝐧𝐲 (𝐒𝐈𝐏/𝐕𝐨𝐈𝐏) + 𝐓𝐰𝐢𝐥𝐢𝐨/𝐏𝐥𝐢𝐯𝐨 + 𝐀𝐬𝐭𝐞𝐫𝐢𝐬𝐤
• SIP trunking integrations (inbound/outbound), routing, call control
• Asterisk: IVR, queues, dialplans, conferencing, PBX integrations
• Twilio Programmable Voice: webhooks, recordings, call flows, media streaming
• WebRTC ↔ SIP bridging (browser/app calling into PSTN)
✅ 𝐕𝐨𝐢𝐜𝐞 𝐀𝐈 (𝐒𝐓𝐓/𝐓𝐓𝐒 + 𝐂𝐨𝐧𝐯𝐞𝐫𝐬𝐚𝐭𝐢𝐨𝐧𝐚𝐥 𝐀𝐈) 𝐭𝐡𝐚𝐭 𝐰𝐨𝐫𝐤𝐬 𝐨𝐧 𝐫𝐞𝐚𝐥 𝐜𝐚𝐥𝐥𝐬
• Real-time STT streaming (partials, low latency) + speaker-aware workflows when possible
• Streaming TTS with interruption handling (barge‑in) and turn-taking logic
• Voice agent orchestration (including Vapi-style patterns)
•Call summaries, structured data extraction, CRM updates, analytics
• Guardrails + fallbacks (human handoff, escalation, retry logic)
✅ 𝐀𝐈/𝐌𝐋 + 𝐂𝐨𝐦𝐩𝐮𝐭𝐞𝐫 𝐕𝐢𝐬𝐢𝐨𝐧 (𝐰𝐡𝐞𝐧 𝐢𝐭 𝐬𝐮𝐩𝐩𝐨𝐫𝐭𝐬 𝐭𝐡𝐞 𝐩𝐫𝐨𝐝𝐮𝐜𝐭)
I integrate AI/ML in a production-first way that doesn’t break real-time constraints:
• OCR + computer vision pipelines (live overlays, detection, automation)
• ML/LLM components for classification, routing, QA scoring, intent detection
• PyTorch/TensorFlow integration when custom models are required
• Generative AI features (RAG / knowledge-based responses) with accuracy controls
𝐇𝐨𝐰 𝐈 𝐰𝐨𝐫𝐤 (𝐬𝐨 𝐩𝐫𝐨𝐣𝐞𝐜𝐭𝐬 𝐝𝐨𝐧'𝐭 𝐝𝐫𝐢𝐟𝐭)
𝟏. 𝐐𝐮𝐢𝐜𝐤 𝐝𝐢𝐬𝐜𝐨𝐯𝐞𝐫𝐲: goals, target platforms, expected concurrency, latency KPI, constraints
𝟐. 𝐏𝐥𝐚𝐧: architecture + milestones + risks (written, clear scope)
𝟑. 𝐁𝐮𝐢𝐥𝐝 & 𝐢𝐧𝐭𝐞𝐠𝐫𝐚𝐭𝐞: clean implementation + reviews + docs
𝟒. 𝐏𝐫𝐨𝐝𝐮𝐜𝐭𝐢𝐨𝐧 𝐫𝐞𝐚𝐝𝐢𝐧𝐞𝐬𝐬: monitoring, alerts, load testing, handover
𝐓𝐲𝐩𝐢𝐜𝐚𝐥 𝐝𝐞𝐥𝐢𝐯𝐞𝐫𝐚𝐛𝐥𝐞𝐬
• Working, deployed solution (Docker/Ubuntu)
• Reliable call/stream flows + error handling
• Recording/transcription + storage integration if needed
• Monitoring dashboards + alert rules
• Documentation + runbooks + next-step roadmap

Build VENUE: A Creator-Led Social OTT Platform (Video, Commerce, Chat, Payments)
Usman has been instrumental in bringing The Live Venue platform to life. What impressed me most was his ability to take a complex, high-level vision and turn it into a working product with clean code, strong architecture, and great attention to user experience.
He didn’t just “build what was asked,” he understood the product goals, anticipated edge cases, and proposed smart technical solutions along the way. His communication was always clear and proactive, and every milestone was delivered on time and to spec and he was always good at giving practical advice.
The platform he built performs and looks great, real-time streaming, creator dashboards, and scalable backend all running seamlessly. Working with Usman felt like having a true engineering partner, not just a freelancer.
I’d highly recommend him for any serious product build that requires both technical skill and ownership mindset. We’ll definitely be working together again with him and his team who were equally great.
