Build an AI Assistant for Customer Service & Business Intelligence (Fleet Management)
Our team worked closely with Salman throughout the build, and the outcome speaks for itself. He was patient with us as we made amendments along the way, and where there were overruns caused on our side, he stayed accommodating and kept the work moving. The support was consistently good, and there were extras thrown in that we had not asked for. Most importantly, the final product was delivered. We would gladly work with him again.

𝗥𝗲𝗰𝗲𝗻𝘁 𝘄𝗼𝗿𝗸:
→ Built inbound and outbound AI voice agents that handle calls, qualify leads, and book appointments without a human touching the phone. Live and running for real operations.
→ Built custom AI assistants and chatbots connected directly to databases, pulling live data to answer questions and return dynamic, real-time results instead of canned responses.
→ Built full GoHighLevel automation from lead intake to closure, powered by an AI SMS SDR that replies instantly, follows up on its own, and flags leads for human review when they need a real person. The system sorts hot and cold leads automatically and delivers daily insights across the whole pipeline. Running across healthcare, real estate, HVAC, and law firm operations.
→ Analytics system tracking $2.4M in revenue in a single month for a high-ticket sales operation; $4.6M all-time. Leadership watched $1.4M close in one week from a single screen; rep performance, pipeline stages, conversion rates, all live.
→ Upgraded a real-estate operation from manual Excel sheets to a custom dashboard powering automations across their pipeline without manual work. Claude plugged into the same data, answering business questions, flagging bottlenecks, and surfacing daily reporting improvements.
→ Worked with SaaS product owners building their MVPs from prototype to production, then scaling them. Multi-client Stripe billing for clean onboarding, RAG systems making AI features actually deliver, and the production engineering to ship something real.
→ A founder running a live AI product had watched his in-house dev team struggle for three months to get the AI behaving the way he wanted. Came in, worked the problem from first principles, got it shipping the experience he envisioned. Live with real users.
I also help founders figure out what to build and where things break, and consult on their more novel problems: new AI use cases, LLM behaviour, agent architecture, voice agent design, making your vision come to life.
Claude Code is my daily infrastructure. Multiple businesses run their day-to-day on what I've built; ops, SaaS, LLM products, voice agents, all in production.
If you've got something to build or fix, let's talk.
