A WhatsApp-based AI assistant for creating one-off and recurring reminders via natural-language messages, synced to Google Calendar; live in production with 50+ active users. Parses intent, schedules events, and sends timely notifications; built with Next.js 14, Supabase, and WAHA for multi-user SaaS scalability, with OTP login, a task dashboard, and reminder processing and delivery orchestrated in n8n. Handled real-world issues including Cloudflare bot-protection conflicts, database access rules (Supabase RLS), and WhatsApp endpoint configuration.
Self-managed server · Jun 2025 – Present
Built from scratch on Ubuntu Server 24.04: containerised services (n8n, Dify, WAHA, Outline and others) managed through Portainer, routed via Traefik, with Tailscale and Cloudflare Tunnel for secure remote access. Diagnosed and fixed operational issues including container OOM kills, Docker DNS resolution failures (daemon-level configuration), and multi-service tunnel routing.

Brand website for a two-in-one communion product (grape juice and unleavened bread), built to restore the practice of communion as a daily act of worship, with a QR-code scripture draw for a daily blessing.

An MCP server that lets Claude Code browse and pull in conversations from your claude.ai account, so a chat from your phone this morning is available in your editor by afternoon. Read-only access via list/read/save tools, with session credentials stored in the OS keychain rather than config files.
A password vault and browser extension that mixes real quantum randomness (ANU QRNG) into key generation, with an honest, non-hyped account of what that actually buys you.
An n8n workflow that automatically fetches the latest GitHub Trending repositories, cleans the data, and sends a nicely formatted daily email digest.
