Hi, I'm John Chael Ortua
AI Automation &Agent Developer
I design and ship AI-powered apps and n8n automations that go from idea to production.
Structured by default.
Every time.
A repeatable process from research to shipped product — combining AI tools, structured docs, and hands-on development.
Perplexity + NotebookLM
Research & study the concept

Plan the tech stack
Implementation

Build
Develop with live documentation
Every project I take on ships with docs like these.
Things I've shipped.
5 projectsA collection of projects built end-to-end — from research and scaffolding through to live deployment.
Talk Reminder
Event organizers were manually chasing speakers for follow-ups across multiple channels, wasting hours of coordination time.
Cross-platform scheduling tool (web + Android) that automates speaker reminders via email, Telegram, or Facebook Messenger using Supabase and Vercel Cron.
Wil-C
Field officers at a wastewater facility used paper logs for compliance reporting.
PWA with offline form submission, automatic sync, and PDF report generation.
Offline Restaurant Ordering
Restaurant staff had no way to take orders during internet outages, causing service disruptions and lost revenue.
Offline-first LAN ordering system where customers scan QR codes to order from their table — all synced in real-time to the admin dashboard via Socket.IO, no internet required.
Online Restaurant Ordering
A multi-branch restaurant had no unified online presence — no ordering system, no branch management, no inventory control per location.
Full restaurant website with online ordering, cart and checkout, per-branch menu availability, and a complete admin dashboard — built with vanilla HTML/CSS/JS and Supabase.
Ortuma Project Launcher
Project setup, planning, and progress tracking lived across too many tools — slowing every build from idea to ship.
Electron + Gemini AI desktop app that automates project scaffolding, tracks progress across workspaces, and generates implementation plans — basically my own AI dev assistant.
Things I've automated.
5 workflowsAutomations and AI agents built with n8n.
Kira — AI Expense Tracker Bot
AI bot that turns Telegram messages and receipt photos into organized expense records automatically.
B2B Lead Gen & Enrichment Pipeline
Scrapes Google Maps for local businesses, finds verified decision-maker emails, and writes AI-personalized icebreakers to a sheet.
Keith - RAG Document Q&A Telegram Bot
Auto-ingests PDFs/Docx from Google Drive into a vector store and answers questions via Telegram.
Cold Email Outreach Sender (Resend + Google Sheets)
Sends personalized cold emails from a Google Sheet via Resend, with automatic status tracking and rate limiting.
AI Voice Receptionist — Appointment Booking & Availability
Voice AI answers calls, checks calendar availability, books appointments, and emails confirmations automatically.
A self-taught dev building
production-ready software.
I'm John Chael Ortua — a self-taught developer from the Philippines who builds production-ready web apps using modern tools and AI as leverage, not a crutch.
My workflow is documented, structured, and repeatable. Every project ships with implementation plans, progress logs, and clear handoff docs.
Outside the screen: basketball, film, and motorcycles.
Tools that compound.
The stack I reach for when shipping — tools and models that compound my output.
“I ship real products — no team, no budget, just resourcefulness and the right tools.”
Let's build something together.
I'm open to freelance contracts, part-time collaborations, and interesting projects — especially anything involving Next.js, automation pipelines, or AI integration. Philippines-based, remote-friendly.
