Share of my 2025–2026 projects that use each skill

  • Two decades building custom full-stack web solutions — real-time multi-user apps, dynamic PDF/image rendering, and mobile apps — leading local and distributed teams.
  • 2026: replaced archpaper.com's event plugins with a Workers calendar (4,326 events migrated); shipped Swiftly, BetterBlast, a multi-tenant portal, and an MCP server.
  • Full creative-technologist range plus MSP services: UX/UI, SEO, web3, networking, VOIP, cloud, and design/marketing/video production.

  • Architected an event-management platform — 600+ features across 10+ microservices — serving 10,000+ concurrent users per event at 99.9% uptime.
  • Built offline-first iOS/Android apps with SQLite sync, push, and store CI/CD; rebuilt the attendee app as CONFlux 5 (Nuxt 4, Capacitor 8), reaching v2 parity in a week and shipping to both stores.
  • Engineered a real-time WebSocket chat system (threads, presence, DMs) as a framework-free shared layer used by both app generations.
  • Designed 200+ Postgres/Supabase API endpoints with multi-layer Cloudflare (R2/D1) caching at sub-100ms; plus Vue-SSR email, analytics, RBAC/OTP auth, CVENT, certificates, and entity-level ACL.
