Isaac A.
AI Agent Developer | AI Integration, Chatbots, Voice AI & Claude Code
I build AI agents, automations and AI-built apps that take real work off your team: voice agents that answer and book calls, n8n and GoHighLevel workflows that follow up every lead, and full web and mobile apps shipped fast with Claude Code and Supabase. Top Rated · 100% Job Success · NoCodeZiggy ⭐⭐⭐⭐⭐ "Isaac combines technical excellence, dedication, and integrity in a way that is rare to find." (Upwork review, 8-month mobile app build) Not templates. Not demos. Real systems, built, tested and documented. --- WHAT I BUILD AI AGENTS & VOICE AI Agents that answer phones and chats, qualify leads, book appointments, handle reschedules and follow up 24/7, with a person kept in the loop wherever a wrong answer would be costly. • Nancy: a fully autonomous AI receptionist for a UK health clinic. Inbound calls, live calendar bookings, reschedules and post-call SMS (ElevenLabs, n8n, Google Calendar, Twilio) • Maria: a bilingual English/Spanish real estate voice agent connected to HubSpot (Retell AI, n8n) • A DST-aware outbound calling system for a Chicago client (Vapi, GoHighLevel, n8n) • An inbound intake agent for a medical weight loss clinic (Vapi) AI WORKFLOW AUTOMATION Lead capture to CRM update to follow-up SMS, document processing, reporting and admin. Multi-step n8n pipelines with logging, retries and alerts, so failures are visible instead of silent. Tools: n8n · Make · Zapier · OpenAI · Claude · Webhooks · REST APIs AI-BUILT APPS (VIBE CODING, DONE PROPERLY) I use Claude Code to design, build and ship production apps fast: Supabase database and logins, payments, deployed on Vercel with your own domain. If your app was started in Lovable, Bolt, Replit or Bubble and stalled on the way to production, I take it the rest of the way. • LoopDxb: a fashion resale marketplace, from Bubble MVP to an Expo / React Native mobile app • A custom CRM SaaS of my own, built with Claude Code • MCP server builds that let AI agents use a company's own tools and data • I also teach vibe coding: building with Claude Code, adding Supabase, and going live with GitHub and Vercel Tools: Claude Code · Supabase · React Native / Expo · Node.js · Vercel · Bubble CRM BUILDS (GoHighLevel) Full GHL setups: pipelines, automations, nurture sequences, A2P 10DLC, sub-accounts and SaaS mode, with AI agents and voice wired in. Built for credit coaching programs, multi-business operators and healthcare practices. --- HOW WE START 1. Tell me the task your team repeats most, or the app you want live. 2. I reply with a plan: the first milestone, what it costs to build and to run, and where a person should stay in charge. 3. We ship that first piece, make sure it pays off, then move to the next. Everything runs in your own accounts, fully documented.
