ERD Studio in action — designing a data warehouse on a canvas inside VS Code

ERD Studio

vs code extension · open source · on the marketplace

Visual ERD designer for dbt. Design your data warehouse on a canvas, in your repo. Ships with an erd-studio skill so your coding CLI harness (Claude Code, etc.) can read and edit the warehouse directly. Takes a team from “we need a new model” to production in days, not weeks.

Animated timeline — Computers, internet, cloud each took ~10-23 years to reach default; AI is on track to do it in 8.

The AI Strategy

essay · framework for leadership conversations

A view of the next decade: AI is moving from novelty → tool → default in about 8 years (computers took 23). The durable part isn’t the chosen tool — it’s the middle layer a company owns: skills, knowledge, policy, evals.

The Big Red roster timeline — coloured time-slot bars across the day showing when each staff member is available between their fixtures

My local café — Big Red

next.js on cloudflare workers · live · api integration

I know the owner. Built him a one-click scheduling tool that pulls every casual’s SSFA soccer fixtures and shows when each person is actually available behind the counter. Replaces a weekly cross-referencing job nobody enjoyed. Next.js + Cloudflare Workers + KV.

Live demo — Anthropic Managed Agents cloud session running the sales-quoting orchestrator, showing the agent loop, six specialists, and the raw event stream

Sales Quoting Agent

multi-agent claude poc · cloudflare worker · anthropic managed agents

POC I built end-to-end for a friend’s logistics business. Orchestrator + six specialists (RFQ parser, rate lookup, surcharge, terms, margin, drafter). Local MCP server, Cloudflare Worker, and Anthropic’s Managed Agents cloud — same loop, three runtimes laptop → edge → cloud.

Work

AI / Data Engineer

John Holland Group

2022—present

  • Built and shipped ERD Studio — an open-source VS Code extension on the marketplace that uses LLMs to compress dbt data-warehouse delivery from five months for a whole team down to two weeks for one engineer with AI.
  • Built and shipped the BI Portal — an internal app that overhauled how the org navigates Power BI dashboards (Netflix-for-KPIs UX). Inside it, the team now scaffolds new dashboards in React with AI assistance. In production with full CI/CD, deployed as a Databricks App on the Databricks AI Dev Kit.
  • Use Claude Code as a daily multiplier — agentic coding, custom skills, MCP integrations. Built personal tooling around it, not just consumed it.
  • Wired systems together end-to-end — GitHub Actions, dbt Cloud, Databricks workflow APIs, webhook triggers and event-driven jobs. Manual processes become hands-off pipelines.
  • Designed full-stack data workflows across AWS, dbt, Databricks and Power BI — ingestion, transformation, modelling, reporting.
  • Modelled data with bronze / silver / gold architecture — aggregated, scalable, observable.
  • Built high-performance DirectQuery KPI dashboards in Power BI — raw operational data to executive summary with minimal latency.
  • Designed and implemented the team’s dbt CI/CD — GitHub Actions pipelines on every PR, environment promotion, automated tests, deploys into Databricks. Live in production.
  • Presented an AI primer to ~80 IT staff and ran brownbags on AI-assisted data engineering for the wider team.

Systems Engineer

John Holland Group — Sydney Gateway

2018—2022

  • Systems Lead on a multi-year CBD infrastructure project.
  • Built and rolled out Microsoft Power Platform tooling (Power Apps, Power BI, Power Automate, SharePoint) across the site — workflow automation before it had a marketing department.
  • Digitised manual workflows end-to-end and trained the team into the new systems.
  • Administered the project quality software (PPW) and produced the analysis that drove decisions.

Site Engineer

CPB Contractors — WestConnex New M5

2015—2018

  • Site Engineer on Stage 2 of the New M5 motorway tunnel.
  • Ran site setup, decline excavation and structural steel install at Arncliffe.
  • Owned daily reporting, program updates, cost forecasting and material procurement.
  • Interfaced with designers and supervised the field workforce — safety-critical operations, no room for sloppy data.
