Full Stack AI Developer | AI Agents, Voice AI, RAG, n8n, MCP, SaaS MVP

Most AI automations break in production. I build production-ready AI agents, RAG pipelines, Voice AI systems, and n8n workflows that plug directly into your CRM or SaaS product. 100% Job Success. Zero disputes. Every system I ship runs daily without babysitting. Before I explain tools or tech stack, let me confirm one thing: do you want something that works now, or something that scales later too? Most automation fails not from bad tools but from bad architecture. I design systems that handle edge cases, respect rate limits, manage token costs, and scale as you grow. If automation is the wrong answer for you, I will say that instead. WHAT I BUILD AI Agents and Multi-Agent Workflows Agents that research, qualify, route, draft, and follow up. Wired into your CRM and internal tools with n8n, MCP, LangChain, and custom APIs. Tool calling, human-in-the-loop approvals, escalation logic, error handling, and audit logs. Not prototypes. Production systems. Voice AI and Conversational AI Inbound and outbound voice agents using Vapi, Retell, ElevenLabs, and Twilio. They book appointments, qualify leads, and handle support calls, transferring to humans only when it matters. Connected to your CRM and calendar so every call produces a tracked outcome. RAG Systems and Knowledge Bases Retrieval-Augmented Generation pipelines using LangChain, vector databases, and semantic search. Assistants that answer from your own documents, SOPs, and support tickets, with citations and source tracking you can trust. Not generic LLM responses. Full Stack AI SaaS MVPs End-to-end AI product development. I build the web application, database schema, API layer, and orchestration that houses your agents. React, Next JS, Python, FastAPI, PostgreSQL, Supabase, AWS. From architecture to deployment, so startups ship faster. Workflow Automation and API Integration Complex multi-step workflows in n8n, Make, and Zapier. Conditional logic, routers, webhooks, HTTP requests, data transformation, scheduling, and error handling. Connecting CRMs, email, calendars, databases, payments, and third-party APIs into one pipeline. HOW I BUILD -I map your process before I build. You approve scope first. Clear milestones. No surprises. -Everything ships with error handling, retries, cost caps, and monitoring. The difference between automation that demos well and automation you can forget about. -I ship an evaluation harness with every build. You get a test set and accuracy numbers you can run yourself, before launch and after every change. -Full documentation plus a recorded handover video with every delivery. Your team owns it. No dependency on me. WHY CLIENTS KEEP COMING BACK -100% Job Success Score across every contract. Zero disputes. Every delivery completed without issue. -Clients describe me as a clear communicator who delivers error-free workflows with exceptional attention to detail. -I have led technology strategy, software development, and engineering operations for startups and SaaS platforms. I do not just connect nodes. I design systems. -Certified in n8n, Make, and Zapier. Proof of tool mastery, not just tutorials.

You will get a walkthrough of how I would automate it. No cost. No commitment. If I cannot help, I will tell you who can. Want to go deeper? Book a paid 30-minute architecture review. You leave with a written build plan, a realistic cost range, and what I would build versus outsource. You own the plan whether or not you hire me. Ready to eliminate repetitive work and build an AI system that actually runs? Message me and let us architect yours.
