Multi-Tenant CRM Backend Development & WhatsApp Bot Integration
I really enjoyed working with Syed on this project. He played a key role in developing and improving the backend, supporting the AI logic, and helping structure the system to move toward a scalable SaaS solution. He was always responsive, proactive, and open to feedback, which made collaboration smooth and efficient.
Syed showed strong technical ownership and commitment, even when we faced external dependencies and blockers. I would gladly work with him again and recommend him for complex AI and backend projects.

I built my first Voice AI agent 22 months ago. It worked perfectly in testing. Then a caller with a heavy accent asked a question while their dog barked in the background, and the whole thing collapsed.
That project taught me something most AI developers learn too late: the demo is 10% of the work. The other 90% is everything that can go wrong - bad audio, CRM timeouts, users who say "um" fourteen times, edge cases nobody warned you about.
Now I only build AI that handles the chaos.

Stellarcs .ai takes 40+ real estate calls daily. Not test calls - actual leads, live conversations, 92% intent accuracy measured across thousands of interactions. Built on VAPI with ElevenLabs voice, GoHighLevel CRM sync, and Google Calendar booking. It qualifies buyers, handles objections, and hands off to human agents without dropping context.
Dealer Voice answers research questions across 15,000+ academic papers. Hierarchical chunking, hybrid search with pgvector, Cohere reranking, and cited answers. It says "I don't know" when retrieval confidence is low. Researchers trust it because it doesn't make things up.
lawbrarian .com generates legal documents with jurisdiction-aware retrieval. 700+ documents created with proper citations pulled from the right statutes. React frontend, Python backend, pgvector for legal precedent matching.
Stellae .ai handles hotel reception calls - booking inquiries, room availability, guest requests. Retell for voice, n8n workflows for automation, webhook integrations with property management systems.
𝗛𝗼𝘄 𝗜 𝘄𝗼𝗿𝗸
I take on Voice AI agents, RAG systems, and AI MVPs. I'm useful when you're past the "exploring AI" phase and need something deployed. Less useful if you're still figuring out whether AI makes sense - though I'm happy to tell you if it doesn't.
Most of my projects are $2K–25K and take 2–6 weeks. I don't disappear mid-project, I document everything, and I build with handoff in mind so you're not dependent on me forever.
