You will get a Custom GPT Actions connected to a secure Supabase backend
Project details
Your Custom GPT can talk — but it can't do anything yet. It can't log a record, look something up, or save what a user told it, because it has no backend to call. That's what I build: the secure data layer behind your GPT.
I create the API and Supabase (Postgres) database your Custom GPT calls through Actions, so it reads and writes real data, not just chat. Staff logins, form submissions, status updates, lookups, alerts — whatever your GPT needs to make happen, happens for real and gets saved.
What sets this apart:
• I've built this exact architecture in production — Supabase behind an authenticated API, role-based access, secure token auth, and automated email/sheet syncs. This isn't a first attempt on your project.
• Security-first by default: your database key never leaves the server, and the GPT never touches the database directly.
• You see it before we start — I sketch the architecture so you know exactly how the GPT, API and database fit together, and I run a live end-to-end test before handover.
Tell me what you want your GPT to be able to do, and I'll show you how it fits together.

About Mohsan
AI Automation Expert | n8n, WhatsApp & AI Agents for Small Businesses
Dewsbury, United Kingdom - 3:42 am local time
That's exactly what I build systems to eliminate.
I design AI-powered automation using n8n, WhatsApp Business API, and AI agents (OpenAI/Claude/Gemini) that handle customer replies, capture leads, book appointments and move data between your tools automatically — so nothing falls through the cracks.
I'm not learning this from tutorials — I run Pivot Bureau, an agentic AI agency, and I've built and shipped these systems for real: a WhatsApp self check-in platform for short-term rental hosts, a WhatsApp auto-quote assistant for tradesmen that replies and quotes jobs instantly, and AI receptionists that answer customer questions and book appointments 24/7. I also build AI-ready websites and can tighten a site's technical SEO if that's part of the job.
If your business is losing time or leads to manual back-and-forth, I'd be glad to look at your specific workflow and tell you exactly what I'd automate first — no generic pitch, a real plan for your setup.
Steps for completing your project
After purchasing the project, send requirements so Mohsan can start the project.
Delivery time starts when Mohsan receives requirements from you.
Mohsan works on your project following the steps below.
Revisions may occur after the delivery date.
Kickoff & scope
We confirm exactly what your GPT should be able to do, what data it reads or writes, and how users are authenticated. You share the idea once; I turn it into a clear endpoint plan and a quick architecture sketch before any code is written.
Design the schema & endpoints
I design your Supabase tables and the REST API your GPT will call — then send you a simple architecture sketch so you can see how the GPT, API and database fit together before any code is written.
