The arc · Growth to automation
I do the job by hand until it produces a number. Then I build the system that does it.
Before I automated anything, I did the work myself. This is how one skill, social content, went from manual work to an AI agent.

The problem
The account started as a company brand and was not moving. I repositioned it around the teacher as the authority, because a person converts better than a logo. Then I wrote everything myself.
What I built
- By hand: I wrote the copy and the script of every video for 6 to 8 months before anything scaled.
- The format: a video format I created, not copied from a trend, took the account from 700 to 15,000 followers.
- The reach: one video passed 700,000 views, driven by the copy and social SEO in captions and spoken keywords. The account reached 42,298 followers, 100% organic, with no ads.
- The data: I pulled 100 posts through the official Meta API and found that carousels beat reels on reach and saves, even though the account posted more reels.
- The agent: I distilled the method into a Custom GPT with a knowledge base I curated. It writes the script, the on-screen text and the keywords that need to be said out loud to be found.
Runs alongside
- Sales replies by hand became the WhatsApp sales agent.
- Exercises written by hand became the n8n content engine.
- Meta integration (lead capture, daily insights, comment replies via the Graph API) was built and tested, then switched off on purpose to protect the account.
What the agent is, honestly
It is a Custom GPT with a curated brand knowledge base, not a RAG pipeline. The value is the method inside it, which I proved by hand first. It can move to n8n when it needs to run headless.

My role
I owned the marketing strategy and growth of the brand account: positioning, format, copy and social SEO. The teacher is the face of the brand. The strategy and the systems are mine.
Why there is no public access
The agent is a private Custom GPT built on the brand's internal knowledge base. I can run it live on a call and show how it builds a script.
I can show it running live on a call.
I open the real system, with personal data protected, and answer anything you want to know about how it is built.
