I help businesses connect their platforms and automate repetitive work through API integrations. Typical projects: syncing Shopify orders with CRMs and Xero, building WhatsApp systems with Twilio, connecting payment gateways, and adding OpenAI to real workflows. I also build AI-powered websites and custom backend systems. Stack: Laravel, REST APIs, webhooks, Shopify API and n8n. I confirm scope before starting, write clean code you fully own, and stay available after delivery. Tell me which systems need to talk to each other and I will suggest the simplest way to connect them.
