Profile Description

n8n automation engineer and CS graduate (UPLB) who builds end-to-end AI workflow pipelines — and the full-stack apps behind them. I deploy and document what I build.

Stack:
- Automation: n8n (self-hosted Docker), Claude API, Google Sheets/Docs API v4, Gmail API, Slack API, HubSpot CRM API, OAuth2, webhook + wait/resume patterns
- Web: TypeScript, React, Next.js, Node.js, Express, PHP Laravel, Tailwind
- AI: Anthropic API, Voyage AI, RAG pipelines, vector search, structured-output prompting
- DevOps: Docker, GitHub Actions, Railway, Vercel, Linux

Available 8 hrs/day. Comfortable working US hours / any timezone — I overlap, I don't just queue work overnight. Set up to deliver, not just talk.
