Client Delivery

Villa Oliveto

Social Content Engine

In Production

A content workflow for a Singapore olive-oil brand's Facebook and Instagram, running in production.

  • Strategy and product info go in once; the system drafts each week's topics and captions in the brand's voice
  • The marketing team reviews every post — approve, adjust with a note, or reject — before anything is published
  • Approved posts are ready to publish; once live, each one is matched back automatically for tracking
  • Post performance flows back into a weekly summary that shapes the next plan

See the results: search "Villa Oliveto Singapore" on Facebook or Instagram.

How I Work

01

Your team stays in control

AI drafts, people approve. Every automation has a clear review step, so nothing goes out that your team hasn't seen.

02

Fixed scope, pay on approval

Clear scope agreed up front. Payment is released once you've reviewed the delivery and it works end to end.

03

Documented handover

You get an operating guide — how it works, day-to-day use, basic troubleshooting — plus 30 days of bug fixes after delivery.

04

No surprise running costs

You know the monthly API and hosting cost before we start, and the setup is built to keep it low.

What I Do

AI Workflow Automation

Claude-powered drafting, classification and reporting in n8n, Make or custom code — with a human approval step where it matters.

Spreadsheet Systems

Google Sheets, Apps Script & Excel systems for orders, inventory, scheduling, payroll and finance — protected formulas, live dashboards.

Notion & CRM Systems

Notion workspaces, CRM pipelines and internal tools shaped around how your team actually works, not a generic template.

System Integration & API

Connect the tools you already use — Meta, Google, Notion, CRMs, chat apps — with reliable sync, retries and error alerts.

Demos & Products

n8n Email Automation Pipeline

Automation Demo

Gmail → AI classification → Notion pipeline built in n8n: incoming mail is classified by an LLM and routed into three Notion databases, with de-duplication for safe re-runs and an error branch that logs failures to disk. Watch the 2-minute demo — all inbox data is fictional.
