Ayaz K.

AI Developer building AI agents, AI voice agents, RAG chatbots and AI automation that run in production. 1,495 hours on Upwork at 100% Job Success, with 9+ years of production engineering behind the AI work. Most AI builds work in the demo and break the week after. Retrieval returns the wrong chunk. Token costs triple. The agent loops. As an AI Developer I build for the part after the demo, because I spent nine years shipping enterprise software before I built my first AI agent, and agents are still software. AI VOICE AGENT DEVELOPMENT As an AI Voice Agent Developer I build inbound and outbound voice agents for reception, appointment booking, lead qualification, support and follow-up. Vapi, Retell AI, Twilio, ElevenLabs, Deepgram, Whisper and the OpenAI Realtime API. Barge in and interruption handling, filler audio during tool calls, warm transfer to a human, full transcripts pushed to your CRM. AI AGENT DEVELOPMENT As an AI Agent Developer I build autonomous agents that reason, call tools, update databases and run multi-step workflows. LangGraph, LangChain, CrewAI and the OpenAI Agents SDK. Multi-agent systems with validation gates, bounded retries and human approval before anything irreversible. Per-run token and cost caps so the LLM bill stays predictable. Every agent decision logged and traceable. RAG AND AI CHATBOT DEVELOPMENT As a RAG Developer and AI Chatbot Developer I build retrieval systems over PDFs, contracts, internal docs, knowledge bases and live databases. Chunking built around your document structure, embeddings, hybrid retrieval, reranking, metadata filtering and citations on every answer. Pinecone, Qdrant, Chroma, pgvector and Weaviate. An eval harness so you can measure answer accuracy instead of hoping for it. Deployed into web widgets, WhatsApp, Slack and voice. AI AUTOMATION AND INTEGRATION As an AI Automation Developer I replace manual work with reliable workflows. Document processing, extraction, classification and summarization at volume. n8n, Make, Zapier and Python, wired into HubSpot, Salesforce, Attio, Slack, Gmail, Outlook, Notion and Stripe. Idempotent writes so a retry never duplicates a record. AI SAAS AND FULL STACK DEVELOPMENT As a Full Stack AI Developer I build the product around the AI. Next.js, React, TypeScript on the front. FastAPI, Python, Node.js on the back. PostgreSQL, Supabase, Redis. Multi-tenant SaaS with role-based access, Stripe billing, usage metering and admin dashboards where you can audit and override anything the agent did. TECH STACK Models: OpenAI GPT-4o, Anthropic Claude, Gemini, Llama, Mistral Agents: LangChain, LangGraph, CrewAI, MCP, tool calling, structured outputs Voice: Vapi, Retell AI, Twilio, ElevenLabs, Deepgram, Whisper, OpenAI Realtime RAG: Pinecone, Qdrant, pgvector, Chroma, Weaviate, hybrid search, reranking Automation: n8n, Make, Zapier, Celery, webhooks Backend: Python, FastAPI, Django, Node.js, REST APIs, WebSockets Frontend: React, Next.js, TypeScript, Tailwind Data: PostgreSQL, MongoDB, Redis, Supabase Infra: Docker, AWS, GCP, Vercel, CI/CD WHY CLIENTS KEEP ME 100% Job Success Score across every completed contract. Microsoft Certified. 9+ years of production engineering, six of those leading enterprise .NET and C# teams before moving to AI. Retrieval tuned and measured. Guardrails and fallbacks on every LLM call. Evals so quality does not drift. Clean architecture your next developer can read. HOW I WORK Scope first, then a small paid pilot, then build. Working software early and often. No black boxes, no month of silence. Custom code only, not no-code tools. Send me your idea, your existing app, your workflow or your documents. I will review it and tell you straight whether an AI agent is the right tool, or whether a hundred lines of Python does the same job for a tenth of the cost.
