You will get API integration REST API webhook automation n8n Make com Zapier
Top Rated
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

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.

Lagos, Nigeria - 5:35 am local time
I am George, an AI Agent Developer specializing in LLM-powered automation, voice AI agents, and n8n workflow systems. 20+ 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, handling real business operations for real clients.
ANSWERS TO WHAT YOU'RE PROBABLY WONDERING
Can you actually build what I need?
Yes. I build AI agents that make decisions, trigger actions, and integrate with your existing stack via API using OpenAI, Claude, and LangChain as the intelligence layer. If your platform has a REST API, a webhook, or an HTTP endpoint, I can connect it and put an AI agent layer on top. It handles logic, routing, and data transformation automatically. I've integrated over 200 platforms across CRM, communication, payments, scheduling, & data tools.
What kind of AI agents do you build?
Voice AI agents using Retell and Vapi that qualify inbound leads, handle calls, book appointments, and sync contact data to your CRM with zero manual input running 24 hours a day, 7 days a week. AI chatbots for websites with full business logic, handoff flows, and memory. RAG-powered assistants trained on your internal documentation so they answer questions accurately without hallucinating. AI-powered lead generation systems with LLM scoring, enrichment, and automated multi-channel follow-up sequences. MindStudio and custom AI agent builds connected to GoHighLevel, Airtable, & your existing workflow infrastructure.
What automation platforms do you work with?
N8n and Make com are my primary build environments for LLM-powered automation and workflow systems. I connect them to GoHighLevel, HubSpot, Airtable, Notion, Stripe, Twilio, Slack, Google Workspace, and any platform that exposes a REST API or webhook. I also handle full Zapier to n8n or Make com migrations. My n8n workflows include advanced conditional branching, error handling, retry logic, and LLM nodes so the workflow doesn't just move data, it makes decisions on it.
What results do clients usually get?
One client eliminated 40+ hours of weekly manual onboarding using a Make com system I built in under a week. Another got a complete outbound AI engine with LLM-powered lead scoring and CRM automation that runs without a sales team touching it. A real estate client now qualifies leads and books appointments 24/7 through a voice AI agent with zero manual input. A GoHighLevel integration I built via n8n resolved a complex JSON middleware issue that blocked three other developers solved within 24 hours of me starting.
Why hire me?
I design automation architecture the way a systems engineer would with error handling built in from day one, retry logic that recovers from API failures silently, and documentation your team can follow without me present. You get a working system with a full walkthrough, not just files and a wave goodbye.
How do you work?
Day 1, I map your existing workflow, identify bottlenecks, and design the AI agent architecture before touching a single node.
Days 2-3, I build and connect using n8n, Makecom, or both depending on your stack.
Day 4, I test, document, and deploy. Most projects are live within 4-7 days.
Who I work best with:
SaaS founders needing AI-powered onboarding and workflow automation. Agencies needing white-label AI agent systems with clean documentation. Sales teams replacing manual lead qualification with AI agents that work around the clock. Businesses on Zapier hitting task limits who need a more powerful stack.
