Project details
Turn missed calls into booked appointments. I build AI voice agents that handle inbound and outbound calls, qualify leads, book appointments, recover missed calls, and log every conversation straight into your CRM and wired into your real systems, not a demo. Built on Retell, Vapi, ElevenLabs, Twilio, and OpenAI Realtime, your agent answers in a natural voice, follows your call script, routes to a human when needed, and keeps your pipeline updated automatically. Ideal for agencies, clinics, home services, and any team losing revenue to slow, manual phone follow-up. I scope the smallest useful first milestone, ship it, and hand it off under your brand.
What you get: inbound/outbound calling, appointment booking, lead qualification, missed-call recovery, human-handoff routing, and CRM logging, configured, tested, and deployed.

Senior Fintech Engineer — AI Financial Intelligence Layer (Saudi Arabia Market)
Mujtaba is technically capable and can build features quickly. The core issues were quality control and ownership. Work was repeatedly presented as complete without being tested, which created problems during time-sensitive external commitments. When this was raised, the response was that I should have taken more control of the product myself. That is the reason I hired a senior engineer. If he needed input or specifications from me to deliver properly, he never asked. Commitments on meeting times and deliverable timelines were not consistently met. A confidential document belonging to another client was also sent to me in error during the engagement. I would recommend building in your own testing and verification process if you work with him.

I build production agentic AI systems across voice, RAG, MCP, and business workflows. Recent work includes a healthcare voice system connected to admissions and CRM workflows, a source-grounded RAG platform managing 1,682+ documents and multi-model content pipelines running at production volume.
I engineer the full path from model response to completed workflow: retrieval, tool use, integrations, evaluation, monitoring, and deployment.

I start with the workflow and the actions the system must complete, then build the smallest production slice that proves it. Delivery includes testing, monitoring, and documentation so your team can operate and extend the system.
If you are building an agentic AI system, adding AI to an existing product, or automating a workflow across your stack, send me what exists and what the system needs to complete.
