I help businesses build reliable, scale-ready systems across Shopify, Airtable, Twilio, WhatsApp and other APIs using AI-assisted automations / workflows. My focus is simple: deliver production-grade solutions that are stable, clear to operate, and built for long-term growth. What clients hire me for: - AI-assisted automation for finance and back-office ops (Xero, Unleashed, invoicing, reconciliation) - Twilio/Zoho SMS and CRM reliability, including AI-drafted responses - Shopify app development and checkout customization - Airtable-based operations that have outgrown spreadsheets - Lead distribution and routing systems (Google Cloud Functions, Airtable, Sheets) - Diagnostics and troubleshooting of broken integrations Recent work, client-verified: 1. Operations Automation Suite & Digital Transformation (Ongoing) - Rebuilt workflows across Xero, Unleashed, Amazon, PayPal, and n8n. Reclaimed 10+ hrs/day reclaimed across six workflows (~AU$4000/month at $20/hr), built in 63 hours total. 2. Twilio + Zoho CRM SMS Reliability (2019-2025, ongoing) - Diagnosed and fixed silent message-delivery failures, then added AI-drafted replies. "I've worked with Mark for years... he's helped dial in our systems with incredible code that always just works." 3. Custom Lead Distribution Platform (2025, ongoing) - Built on Google Cloud Functions, Airtable, and Sheets so the business can scale lead volume without adding headcount. 4. Behaviour Assessment Platform - Delivered a full participant portal, PDF reporting, and admin controls in one month against a three-month quote. "What an absolute joy to work with you... this project was quoted as taking three months by others, yet Mark did it in one." Full case studies with metrics are in my Portfolio section below. How I work: - I ask about the business problem before the tech stack. - I design for reliability: validation, retries, audit trails, exception handling. - Humans stay in the loop wherever a mistake would cost money or trust - AI drafts, a person approves. - I hand off with documentation your team can actually use. Core stack: PHP, Laravel, WordPress, Shopify (React/Remix, Polaris), Node.js, Python, FastAPI, n8n, Make, Zapier, Airtable scripting, Xero, Unleashed, Twilio, Stripe, PayPal, AWS Lambda, Google Cloud Functions, Claude, OpenAI. If you already know the fix and just need it built, I can do that. If you're not sure what the fix is yet, that's usually where I add the most value.
