Recording Transcription Portal Muhammad was great to work with throughout the project. He was professional, responsive, and delivered high-quality work on time. Communication was smooth, and he handled feedback quickly and efficiently. The final result exceeded our expectations, and we’d gladly work with him again. Highly recommended!

Toronto, Canada - 9:25 am local time
I build production-grade AI voice agents, RAG pipelines, and LLM-powered SaaS platforms using Vapi, Retell AI, Twilio, Deepgram, and ElevenLabs. 12+ years as a full stack developer and founder of Tech Stone Global, serving clients across North America.

Most AI developers can build a demo. I ship systems that survive real users, real call volume, real revenue, and strict SLA requirements.

🎙️ 𝐀𝐈 𝐕𝐨𝐢𝐜𝐞 𝐀𝐠𝐞𝐧𝐭𝐬 (𝐂𝐨𝐫𝐞 𝐒𝐩𝐞𝐜𝐢𝐚𝐥𝐭𝐲)

End-to-end AI voice agents and AI receptionists: inbound and outbound calling, appointment booking, lead qualification, real-time transcription, sentiment analysis, CRM integrations (GoHighLevel, HubSpot, custom), and human handoff flows.

✔ Vapi, Retell AI, Bland when you need fast platform-based deployment
✔ Custom Twilio + Deepgram + ElevenLabs pipelines when you need full control over latency, cost, and conversation logic
✔ OpenAI, Claude, and open-source LLMs for the conversational layer

Recent work: HopDial, a VoIP platform with call transcription, AI sentiment analysis, and scalable AWS infrastructure, plus outbound AI calling systems and AI receptionists for SMBs and service businesses.

🚀 𝐑𝐀𝐆, 𝐋𝐋𝐌 & 𝐀𝐈 𝐒𝐚𝐚𝐒

I run my own production products, so I know what breaks at scale and what actually generates revenue:

✔ Legal AI platform: production RAG system (LangChain + vector search) serving ~4,000 active users
✔ ProNotepad: Next.js SaaS with AES-256 encryption, voice-to-text, and AI features. 1,000+ users on web and Android
✔ WhoseNo: reverse phone lookup platform with 2.68M+ phone records and steady daily traffic
✔ WhatsApp-first AI business automation platform, plus AI chatbots for web and WhatsApp

Client work includes real estate transaction platforms (Next.js), pharmaceutical marketplaces (React Native + NestJS), and private dining and booking platforms.

🛠️ 𝐏𝐫𝐨𝐝𝐮𝐜𝐭𝐢𝐨𝐧 𝐒𝐭𝐚𝐜𝐤

Voice AI: Vapi, Retell AI, Twilio, Deepgram, ElevenLabs
AI / LLM: OpenAI, Claude, LangChain, RAG (Pinecone, Chroma)
Frontend: Next.js, React, React Native, Tailwind
Backend: Node.js, NestJS, FastAPI, Python
Databases: PostgreSQL, MySQL, MongoDB, Prisma
Infrastructure: AWS (EC2, Lambda, S3), Cloudflare, Docker
Rapid MVPs: Bubble combined with custom APIs and AI agents when speed-to-market matters

I only list what I've shipped in production, not tools I've experimented with.

🎯 𝐖𝐡𝐨 𝐈 𝐖𝐨𝐫𝐤 𝐁𝐞𝐬𝐭 𝐖𝐢𝐭𝐡

1. Founders building serious voice AI or AI SaaS products
2. SMBs and service businesses (clinics, real estate, agencies) that want AI calling agents to book appointments and convert leads
3. Funded startups scaling from prototype to production
4. Agencies needing a senior AI and architecture partner
5. Teams on Bubble that want real AI and backend systems behind their app

12+ years means I've already made the expensive mistakes, so you don't have to. You get clean architecture, honest timelines, and production-ready systems your next developer won't struggle to maintain.

If you're building something serious with AI voice agents, RAG, LLM apps, or AI SaaS, send an invite and share your idea. I'll respond with a technical breakdown, not a generic pitch.

Keywords: AI Voice Agent Developer, Voice AI, AI Receptionist, AI Agent Development, AI Automation, AI Chatbot, Vapi, Retell AI, Twilio, Deepgram, ElevenLabs, RAG, LLM, LangChain, Full Stack Developer, Next.js, Node.js, FastAPI, Appointment Booking, Lead Qualification
