A selection of things I have built — production work, side projects, and the occasional experiment. Each card includes the context, stack, and links to the live version or source code.
Social platform for solo travelers
A full-stack social app where solo travelers find companions and split travel costs. Built with Next.js 15 and Supabase, it ships authentication, a personalized dashboard, real-time 1-on-1 chat, a friends system, trip plans with discovery filters, and reviews — covered by Playwright E2E tests.
D&D companion for a West Marches campaign
A monorepo companion for an asynchronous, multi-DM D&D 5e world: character management, a browsable rules compendium, a campaign map, and a world-knowledge layer. A Fastify API, a Next.js web app, and a Discord bot share a pure domain package with Zod schemas as the single source of rule truth.
A portable Spec-Driven Development harness
A tool-agnostic SDD harness with a hard rule: no implementation before approved specs. Eight phases and eight specialist agents, pure-markdown specs, and dependency-free validators that enforce requirement-to-task-to-evidence traceability across Claude Code, Cursor, opencode, and Codex.
Ephemeral audio drops that vanish after one listen
Record a voice note in the browser, get a short shareable link, and send it — the recipient plays it once, then it is gone. Chunked uploads stream to a self-hosted MinIO store, Redis enforces the one-listen TTL, and a daily Vercel cron clears expired drops — the whole backend runs on my homelab, reached through a Cloudflare Tunnel.
Geospatial message board on a hexagonal map
Drop anonymous messages pinned to your location on a Mapbox map. Notes aggregate into Uber H3 hex cells, rendered as a word-cloud layer and floating draggable bubbles, with real-time updates via Supabase and a 48-hour expiry.
