I build automation systems that run businesses — not just connect apps.
133+ n8n workflows in production. 10,000+ monthly executions. A full-stack ops platform serving two Shopify brands daily. That's what I've shipped in the last year alone.
I'm Gabriel — an AI & Automation Engineer based in the Philippines, specializing in n8n workflow orchestration, Claude API integrations, and full-stack operations platforms. My background is unusual: I came from business operations and finance before going deep on engineering, which means I understand why a process needs automating — not just how to wire it up.
What I build:
n8n & Zapier workflows — end-to-end automations with error handling, retry logic, and webhook architecture. Not toy demos — production systems with real failure rates I monitor.
Claude / AI integrations — I've shipped an AI outreach engine that generates audits, cold DMs, and emails in a single API call at $0.002 per lead. I work with Anthropic's SDK daily and know how to keep AI costs controlled.
Shopify operations platforms — I built GNexus, a Node.js/Express dashboard replacing 8+ manual workflows for two stores, integrating Shopify Admin API, Lazada Open Platform, Google Sheets, Lalamove, and Supabase into one system used daily by warehouse staff.
API integrations — HMAC-SHA256 signing, OAuth token management, cursor pagination, rate limiting. I've done it properly across Shopify, Lazada, Google Sheets, Telegram, and more.
Tech I use in production:
n8n · Zapier · Claude API · Node.js · JavaScript · Python · Shopify API · Google Sheets API · Supabase · Vercel · SQL · Express.js · Webhook architecture
Background that makes me different:
Before building systems, I spent years inside them — in finance operations, customer support, and business analytics. I've done the manual work your clients are trying to automate. That means I scope projects accurately, communicate clearly, and deliver systems that people actually use.
If you need a reliable automation engineer who ships production-grade work and communicates like a business person — let's talk.
