Building automation AI systems from idea to production
Laguna, Nagcarlan, Philippines
I build production automation systems and AI-integrated tools for international clients. My core stack is n8n (self-hosted), Claude Code, Anthropic Claude API, Gemini API, Python, JavaScript, Supabase, Firebase Firestore, and Vercel. My most complete build is a ManyChat to n8n to Gemini 2.5 Flash to Firestore pipeline handling automated DM replies for a live New Zealand e-commerce client — 312 production executions at 6.73 seconds average runtime with zero missed messages. I also built a VAPI voice booking agent verified end-to-end at 575ms round-trip, and an automated POS reporting system that replaced a full day of manual work for a food business client. I use Claude Code daily through multi-step agentic sessions, maintain CLAUDE.md context files per project, and ship systems that run reliably without hand-holding. Skills and Tools: n8n, Claude Code, Anthropic API, Gemini API, Python, JavaScript, React, Supabase, Firebase, Vercel, REST APIs, Webhooks, ManyChat, VAPI, Airtable, Notion API, Docker, Git, Cursor, Prompt Engineering, AI Agents
