Project details
Hi, I'm Mujtaba (AIOVIX). I've shipped 30+ voice agents that now handle thousands of calls a week for agencies, real estate, and ecommerce brands.
Drowning in calls you can't answer, or paying a team to qualify leads that go nowhere? An AI voice agent fixes both: 24/7, consistent, cheaper than a part time agent.
WHAT YOU GET
• A voice agent that sounds human, not robotic (ElevenLabs quality voices)
• Built on Retell, Vapi, or ElevenLabs, whichever fits your use case
• Integrates with your CRM, calendar, and phone system
• Books meetings, qualifies leads, answers FAQs, handles support
• You edit prompts and routing yourself after handoff (no dev needed)
COMMON USE CASES
• Real estate: buyer qualification, showing booking
• Agencies: cold outreach, discovery call booking
• Ecommerce: order status, returns, pre sales
• Healthcare: reminders, intake, rescheduling
• SaaS: onboarding, tier 1 support, renewals
WHY ME
• 30+ shipped AI products, not prototypes
• Production code (TypeScript, Python, FastAPI), not just prompts
• Clear tier scope, no feature creep, no surprise invoices
• Responsive async (12 hour max reply time)
Order a tier to start, or message me for a custom package.

Job Success
Lahore, Pakistan - 11:58 pm local time
I build AI products that survive real users, real data, and real business workflows: SaaS MVPs, AI agents, RAG systems, voice AI, and automation inside existing products.
⭐ Top Rated Plus | Top 3% of performers on Upwork
✅ 10+ years building SaaS and AI products | 100+ projects delivered
✅ AI that ships: RAG, AI agents, MCP, Voice AI, LLM integration
✅ Full stack: Next.js, React, TypeScript, Python, Node.js, PostgreSQL, AWS
✅ SaaS, MVPs, automation, fintech, healthcare, construction, legal tech, and sales products
You can hire me when:
- You need one AI feature added to an existing app
- You want OpenAI, Claude, Gemini, or MCP integrated into your product
- You need a RAG system over PDFs, documents, knowledge bases, or internal data
- You want a voice AI agent for calls, bookings, lead qualification, or CRM updates
- You have a workflow involving documents, calls, follow-ups, data entry, or reporting that should be automated
- Your MVP is half-built, buggy, slow, or stuck before launch
- You need someone to build a full SaaS product from idea to deployment
I work well on both small and large projects. If the right first step is a quick audit, prototype, bug fix, integration, or one-week milestone, I will tell you that. If the project needs a full build, I can own the architecture, frontend, backend, AI layer, deployment, and documentation.
The part most AI freelancers skip: AI is rarely the whole product. It usually needs a backend, dashboard, auth, billing, permissions, logs, human review, and deployment around it. I build both the AI layer and the product around it.
WHAT I DO:
- AI SaaS & MVP builds: idea to deployed product with auth, billing, dashboards, and AI layer
- AI inside existing products: RAG, agents, MCP, LLM features, document AI, and automation
- Voice AI: agents that answer calls, book appointments, qualify leads, and log to your CRM
- RAG and document AI: source-grounded answers, OCR, extraction, citations, and review queues
- Workflow automation: documents, follow-ups, data entry, reporting, and API integrations
- Rescue & ship: half-built MVPs refactored, hardened, and launched
RECENT DELIVERIES:
- AI sales CRM: call transcription, follow-up automation, multi-tenant pipelines
- RAG document platform with every answer cited to source
- AI financial intelligence platform: open banking + accounting sync into one ledger
- AI voice agents for healthcare and sales, answering real calls daily
- Turnkey B2B SaaS platform for the construction industry, end to end
HOW I WORK:
- I start by understanding the workflow, users, data, and business goal
- I suggest the smallest useful first milestone when possible
- I scope clearly before code is written, so you know cost and timeline up front
- I can work on focused tasks, short prototypes, rescue work, or full product builds
- I work full time on Upwork with overlap for US and European business hours
If you need one AI feature, a quick prototype, a stuck MVP fixed, or a full SaaS product built, send me a short description of what you have and what you want it to do.
I will reply with the clearest next step, the likely scope, and the first milestone I would recommend.

Steps for completing your project
After purchasing the project, send requirements so Mujtaba can start the project.
Delivery time starts when Mujtaba receives requirements from you.
Mujtaba works on your project following the steps below.
Revisions may occur after the delivery date.
Scope call and script draft
I confirm use case, branching paths, voice persona, and what counts as a "win" per call. I draft the system prompt and sample dialogue. You approve before any provider is wired up.
Build the agent on Retell, Vapi, or ElevenLabs
Agent built on your chosen provider, Twilio number wired in, voice and tone tuned. I run 10 sample calls end to end and share the recordings so you can hear it before it touches real contacts.
