Project details
Tired of losing leads to missed calls?
I build AI voice agents that handle appointments, cold calling, booking, and lead generation 24/7 sounding indistinguishable from a real human.
As an AI Engineer with real-time voice pipeline experience (sub-200ms latency), I don't just connect tools. I build production-grade AI calling systems with intelligent conversation design.
What You Get:
Custom AI voice agent (Vapi, Retell AI, Python or Synthflow)
Appointment booking with calendar sync
Outbound cold calling & lead qualification
CRM integration (GoHighLevel, HubSpot, Salesforce)
Workflow automation via Make, n8n, or Zapier + Twilio
Call recordings, transcripts & AI-generated summaries
Industries I Serve:
• Real Estate lead capture & showing bookings
• Healthcare patient scheduling & reminders
• Restaurants reservations & FAQ handling
• E-Commerce cart recovery & follow-ups
• Agencies cold calling campaigns at scale
Full documentation, training, and revisions included. You own all accounts and workflows.
Message me your use case I'll outline a custom solution within 2 hours.

AI Chatbot Developer for Voice-Enabled Assistant
Honestly one of the best freelancers I've worked with. I had a rough idea of what I wanted and Atta turned it into a fully working product. The chatbot answers from my documents perfectly and the voice feature is a nice touch. Very professional, responsive, and knows his stuff. Highly recommend!
About Atta
AI Chatbot Developer | RAG Expert | AI Voice Agents | LangChain
Haripur, Pakistan - 10:57 am local time
5+ years in AI/ML. MS in Artificial Intelligence (NUST). I architect production AI systems for enterprise clients in regulated industries. Every solution survives real-world production pressure — not just a demo call.
----------------------------------------
✅ What I Build
----------------------------------------
▸ Custom AI Chatbots — Trained on your docs, website, or database. For customer support, sales, lead capture, or internal ops. Not a ChatGPT wrapper — a production system with guardrails, fallback logic, context memory, and real accuracy. Built to handle thousands of queries without breaking or hallucinating.
▸ RAG Systems — Your chatbot pulls verified answers from PDFs, knowledge bases, and internal documents instead of making things up. I architect retrieval pipelines handling compliance-grade document volumes with sub-millisecond query latency. 50 pages or 50,000 — built to scale.
▸ AI Voice Agents — End-to-end STT/TTS pipelines with under 200ms response time. Inbound calls, appointment booking, lead generation, customer service — natural-sounding, not robotic. Built on Vapi.ai, ElevenLabs, Whisper, Deepgram.
▸ Multi-Agent AI Systems — Intelligent orchestrators routing user intents to specialized sub-agents. 3+ domain-specific agents collaborate. Deployable on fully local infrastructure for 100% data privacy.
▸ Full-Stack AI Products — End-to-end delivery: LLM logic, FastAPI backend, frontend, cloud deployment. One person instead of three freelancers.
----------------------------------------
✅ Why Clients Choose Me
----------------------------------------
▸ Enterprise AI, not hobby projects — I architect production AI for regulated-industry clients daily. Real users, real edge cases, real compliance.
▸ Production-grade, not demo-grade — My chatbots don't just work in a screen recording. They go live and keep working months later.
▸ True end-to-end delivery — Architecture, LLM selection, prompt engineering, backend, frontend, testing, deployment, post-launch support. One invoice, zero coordination headaches.
▸ Academic rigor (MS in AI, NUST) — I diagnose hallucination, retrieval, and latency at root cause — embedding model, chunking strategy, retrieval logic — not band-aid prompts.
▸ Built for regulated industries — Fully local LLM infrastructure (Llama 3.1 + FAISS) where data never leaves the client's servers. Fintech, healthcare, legal, compliance.
▸ Fast, clear communication — Response within hours.
----------------------------------------
✅ Featured Projects
----------------------------------------
▸ Faith-Based Finance Multi-Agent Assistant — Supervisor agent routing intents to 3 domain-specific sub-agents. Fully local infrastructure (Llama 3.1 + FAISS). Zero data leaves the server.
▸ Real-Time Conversational Voice Agent — <200ms response, dynamic tone and prosody. Handles inbound calls, appointment booking, lead qualification autonomously. Built on Vapi. ai.
▸ Compliance Document Analyzer — Processes thousands of policy and regulatory documents using Docling and ChromaDB. Sub-millisecond query latency.
▸ DataChat (Generative BI Platform) — Natural-language analytics over CSV, Excel, PDF. No SQL, no dashboards — ask, get the answer with auto-generated visualizations.
----------------------------------------
✅ Tech Stack
----------------------------------------
▸ LLMs: OpenAI GPT-4o, Claude, Llama 3.1, LangChain, LangGraph, CrewAI, Hugging Face, LoRA/QLoRA Fine-tuning
▸ RAG & Vector DBs: FAISS, ChromaDB, Pinecone, Qdrant, Docling, Hybrid Search
▸ Voice AI: Vapi.ai, ElevenLabs, Whisper, Deepgram, Real-time STT/TTS
▸ Backend: Python, FastAPI, Flask, REST APIs, PostgreSQL, Redis, Docker
▸ Automation: n8n, Zapier, Make, Twilio, WhatsApp Business API
▸ Deployment: AWS, GCP, Docker, Nginx, Ollama (Local LLM)
