Hammad Z.

I’m an Agentic AI Engineer and AI Agent Developer with 10+ years of experience building software, machine learning systems, AI agents, Voice AI applications, RAG solutions, and Python-based backend systems. I build AI agents that connect with APIs, CRMs, calendars, databases, documents, and internal business tools. These systems can qualify leads, schedule appointments, retrieve information, process documents, update records, manage workflows, and transfer conversations to human teams when required. Recent projects include: • RAG AI Assistant for a live mobile application with 223+ hours of ongoing development. I improved document ingestion, chunking, Pinecone retrieval, NestJS APIs, and response streaming. • Multi-Tenant AI Assistant for an EdTech platform using Django, RAG, vector databases, role-based access, organization-specific knowledge bases, admin approval workflows, speech-to-text, and text-to-speech. • Voice AI Agents for appointment scheduling, inbound customer support, outbound lead qualification, call routing, and live-agent transfer using Vapi, Retell AI, Twilio, LiveKit, Deepgram, and ElevenLabs. • LangGraph AI Agents with tool calling, state management, API integrations, structured outputs, retries, fallback handling, and human approval workflows. • RAG Chatbots and Knowledge Assistants using Pinecone, Qdrant, Weaviate, pgvector, FAISS, OpenAI, Claude, and Gemini. • AI Automation systems connected with CRM platforms, calendars, APIs, webhooks, databases, and internal business applications.
