Project details
Your platforms do not talk to each other. Data gets duplicated, people manually copy information between tools, and nothing updates
in real time because nobody connected the APIs properly. If it has a REST API, a webhook, or an HTTP endpoint, I can connect it.
I build API integration systems using n8n, Make.com, and custom Python and JavaScript for complex logic when native nodes are not
enough. I am Make.com Partner certified with 100% Job Success Score & Top Rated status on Upwork. I have integrated over 200 platforms for clients across ecommerce, SaaS, real estate, & marketing.
WHAT I INTEGRATE:
• REST API connections with proper authentication, Bearer, OAuth, API key, and basic auth all handled correctly
• Webhook listeners with payload parsing, data transformation, conditional routing based on event type
• Bidirectional data sync between CRM platforms, databases, & communication tools with deduplication and conflict resolution
• Custom HTTP module builds in Make.com for APIs without native nodes, including rate limiting retry logic
• Python & JavaScript custom scripts for complex data transformation that native automation nodes cannot handle
• API authentication debugging

AI Voice Receptionist Developer – Retell AI + Make.com/n8n
Delivered exactly what we needed, faster than expected. Clear communicator, proactive with updates, and the voice agent works better than we hoped. Would hire again.

Automate posting from Airtable to Instagram, Facebook & LinkedIn (Make.com)
Brilliant Make.com freelancer exactly what we hired for and more. I run a small brand and was exhausted from posting the same content to Instagram, Facebook and LinkedIn manually every day. He built an automation off our Airtable content calendar that publishes to all three platforms at the time I schedule, automatically marks posts as Posted, handles per-platform on/off, has an optional LinkedIn-specific caption, and auto-resizes images for Instagram (which I didn't know I needed). Broken posts get flagged instead of going out wrong. He then added an engagement-tracking scenario as a follow-up milestone so I can see what actually works. Communication was exceptional throughout clear written updates, an organised testing call, and zero ghosting. Fixed-price milestones with proper Upwork escrow made the whole thing feel safe. Would absolutely hire again.

Ai agent developer to fix broken make.com automation workflow
"Knew exactly what he was looking at he fixed three bugs I didn't even know I had"
I came in thinking this was a simple one-line fix. George diagnosed it in the first 15 minutes of conversation before I even hired him. Turned out there were three separate issues causing my Make.com + Vapi voice agent to fail: a stale assistant ID, a router condition that was never matching correctly, and a broken variable reference in the response module. He found all three, explained each one in plain English, updated me throughout the whole process, and tested it thoroughly before handing it back. Agent's been running clean since.
He also flagged a timeout setting that would've caused intermittent failures down the line didn't have to do that, just did it. If you're dealing with a Make.com or Vapi issue and want someone who actually understands how these systems talk to each other, George is the one. Already planning to bring him back for the next phase.

Zapier systems I've built are handling real calls, real leads, and real money for businesses.
Hi, I'm George your AI Automation and AI Agent Developer. 26+ completed contracts. 100% Job Success Score. Top Rated on Upwork. Make com Partner certified. Every system I've built is running in production right now.
WHAT I BUILD
GoHighLevel Automation & CRM Systems Full GHL ownership sub-account setup, funnels, pipelines, workflows, custom fields, tagging and segmentation. A2P 10DLC registration done right the first time. Email and SMS sequences: booking confirmations, reminders, no-show follow-up, missed-call text-back, review requests.
AI Voice Receptionists & Phone Agents
Retell AI and Vapi agents that answer every inbound call, qualify the caller, book appointments directly into your calendar, and log full transcripts and call summaries to your CRM. Outbound agents that call
leads within 60 seconds of form submission.
AI Agents, MCP & LLM Workflows
Real AI agents that make decisions and take action, not chatbots. Built with OpenAI and Claude APIs, and Claude Code, using structured outputs, tool calling, and prompt engineering. MCP server connections and integrations where AI needs to connect directly to your tools, data,
and internal systems. Multi-agent orchestration, RAG assistants with embeddings and vector databases trained on your own docs, and document processing pipelines.
Workflow Automation & API Integration
n8n, Make com, and Zapier connected to anything with a REST or GraphQL API, webhook, or HTTP endpoint. OAuth2 and API key authentication, Twilio, Google Workspace, Google Sheets, Slack, Stripe, Shopify, Airtable, HubSpot, Pipedrive, ClickUp, WhatsApp Business. Looker Studio
dashboards connected to your automation data for real operational and financial reporting.
Fixing What's Already Broken
Roughly half my work is reviewing, debugging, optimizing and extending automations someone else built broken workflows, webhook payload errors, 401/403 auth failures, duplicate executions, silent failures. I find the root cause, not just the symptom.
HOW I BUILD
I first get acquainted with your business and the manual processes involved. Error handling from the first node, not bolted on after the first failure. Retry logic that recovers from API failures silently. Duplicate prevention so re-runs don't corrupt your data. Documentation plus a Loom walkthrough so your team can maintain it without me. You get a written breakdown of what the system does, what it costs, and where it could fail, before any money moves. Fixed milestones, not open-ended hours. You always know the number. Error handling and alerting on every build, so failures surface immediately instead of silently. Documentation and a walkthrough recording, so your team runs the system without me. US-aligned hours, same-day response on weekdays. 𝗜 𝘁𝗲𝗹𝗹 𝘆𝗼𝘂 𝘄𝗵𝗲𝗻 𝗮𝘂𝘁𝗼𝗺𝗮𝘁𝗶𝗼𝗻 𝗶𝘀 𝘁𝗵𝗲 𝘄𝗿𝗼𝗻𝗴 𝗮𝗻𝘀𝘄𝗲𝗿. Sometimes the process needs fixing before it needs automating.
RESULTS
One client eliminated 40+ hours of weekly manual onboarding with a Make com system built in under a week. A real estate broker now qualifies leads and books appointments 24/7 through a voice AI agent with zero manual input. A GoHighLevel integration built via n8n resolved a JSON middleware issue that had blocked three other developers solved within 24 hours of starting.
WHO I WORK BEST WITH
Agencies needing white-label AI agent and GoHighLevel builds across client accounts. Service businesses losing money to missed calls and cold leads. Healthcare, real estate, insurance, and home service businesses needing AI receptionists. Teams with existing automations that need someone who can optimize and extend rather than rebuild.
