Hello and Mabuhay from the Philippines 🇵🇭 I’m a software engineer with 10+ years of experience building automation systems, AI workflows, and scalable APIs that streamline operations and reduce manual work. I help businesses replace repetitive tasks with reliable, automated systems, saving time, lowering costs, and improving efficiency. What I deliver: AI & workflow automation API integrations & backend systems IoT services & RESTful APIs Data processing & reporting systems Internal tools & dashboards 💡 I don’t just write code, I build systems that make businesses run better. Let’s build something that actually moves your business forward.

Automation and Integration Engineer | n8n, Google Apps Script, Custom APIs, CRM Setup, AI Voice Workflows --- I've spent over a decade building the kind of integrations that quietly make businesses run better — the ones where you stop copy-pasting between systems and things just happen automatically. Most of my work sits at the intersection of business operations and custom code. I set up CRMs like HubSpot and Pipedrive from scratch, then wire them into the tools companies already use — ServiceM8, Xero, Google Workspace, GoHighLevel, Shopify — so data flows where it needs to without anyone chasing it. I've done this for trades businesses, service companies, and growing operations of all shapes. The pattern is almost always the same: three or four disconnected tools, a team manually bridging the gaps, and a straightforward automation that fixes it. More recently I've been building AI-powered voice workflows — connecting VAPI with n8n, Twilio, and GoHighLevel to run outbound calling campaigns at scale. One setup I built for a marketing agency handles around 500 outbound calls per day, fully automated from trigger to CRM update. On the technical side, I build in n8n, Make, and Zapier, but I also write custom scripts in JavaScript, PHP, and Python when the platform connectors don't cut it. I've set up VPS environments from scratch — deploying n8n and other services via Docker and Coolify — so if you're tired of paying per-task pricing at scale, I can move you to a self-hosted setup that you own. I don't overcomplicate things. I ask what's actually broken, figure out the cleanest fix, and build something that keeps working after the project closes. --- EXAMPLE PROJECTS CRM and field service integration A trades business was manually entering the same job data into three separate systems — their CRM, their field service tool, and their accounting software. I set up HubSpot from scratch, integrated it with ServiceM8 and Xero, and built bi-directional syncs between all three. A job created in one place flows through the entire stack automatically. No more double-entry, no more data falling through the cracks. AI voice outbound calling system Built an automated outbound calling pipeline for a marketing agency using VAPI, n8n, Twilio, and GoHighLevel. The system handles around 500 calls per day — qualifying leads, logging call outcomes, and updating the CRM automatically based on how each conversation goes. No manual dialling, no post-call data entry. --- WHAT I WORK WITH n8n (cloud + self-hosted), Make, Zapier, VAPI, Twilio, Google Apps Script, JavaScript, PHP, Python, Docker, Coolify, VPS setup, HubSpot, Pipedrive, GoHighLevel, ServiceM8, Xero, MYOB, Shopify, Stripe, Slack, REST, Webhooks --- GOOD FIT IF YOU NEED — A CRM set up properly from day one, with automations built in — Systems that currently don't talk to each other, connected — An AI voice calling workflow that runs and logs itself — Zapier replaced with something you own and control — Custom scripts for things no connector handles out of the box — Someone who understands your operations, not just the tooling
