About

I'm a solutions architect and software engineer who likes being the person dropped into the gap between "what the customer needs" and "what the product does today." Seven-plus years of scoping, architecting, and shipping integrations for enterprise platforms taught me that the best work happens where product judgment and engineering execution overlap.

By day I architect end-to-end solutions — presales POCs, API integrations, bespoke full stack applications, data flows, and the technical narratives that turn pilots into enterprise contracts. By night I ship things for fun: a production web app, a family of game plugins with real users, MCP servers that wire my tools into AI assistants, and the occasional LED matrix on the wall.

I most enjoy forward-deployed work: embedded with customers, chasing down new ideas, and owning the loop from problem discovery to shipped software.

Projects

Stack Your Cairn

● live

A career wins ledger that talks to your AI assistant.

Production career ledger for logging wins and turning them into promo packets, JD-tailored résumés, and reviews — drafted by your own AI through a hosted, zero-install MCP connector (paste one URL into claude.ai), with every bullet traced to a verified win.

One Repository interface runs it local-first (IndexedDB) or cloud-synced (Postgres + RLS); 12 MCP tools and 206 automated tests — and zero in-product AI calls, so marginal AI cost is $0 by design.

Music Visualizer

● live

The game world dances to its own soundtrack.

RuneLite plugin that parses the game's MIDI music in real time and paints nearby scenery with chromatic pitch-to-color mapping, synced to the track. Published on the RuneLite Plugin Hub.

50 installs in its first week on the Plugin Hub.

RuneHero

● live

Guitar Hero, but the charts are mined from the game's MIDI.

Rhythm minigame inside Old School RuneScape: a chart generator reduces the live track's polyphonic MIDI to a playable melody across five rune-themed lanes, with difficulty tiers, streak multipliers, and an end-of-song rank card.

Smart mode auto-picks the instrument channels carrying the melody. 25+ installs in its first week live on the Plugin Hub.

  • RuneLite

RuneTrivia

● live

Multiplayer trivia across an entire game world.

Head-to-head trivia inside Old School RuneScape: right-click a nearby player to challenge them, an NPC hosts, first to three points wins. A RuneLite plugin client, an authoritative WebSocket match engine (Node + SQLite, on Fly.io), and a Next.js HiScores site — live on the Plugin Hub.

A complete multiplayer system — plugin, real-time backend, and public site — designed, built, and deployed solo.

  • Next.js

Black Box

open source

A combat flight recorder for Old School RuneScape.

RuneLite plugin that continuously buffers game state and, on death or hotkey, dumps the last N ticks — prayers, gear, HP, boss mechanics — as structured JSON built for AI post-mortem analysis. Read-only and ToS-safe.

Designed from day one as an AI data source: the output schema is the product.

  • Java
  • RuneLite
  • JSON

Black Box MCP

open source

The AI coach that reads the flight recorder.

MCP server exposing Black Box encounter logs to Claude — list encounters, pull the latest death, analyze prayer switching — with prompts for combat coaching and post-mortems.

Pairs with the Black Box plugin to close the loop: play, die, ask the AI why.

  • Node.js
  • MCP SDK
  • Zod

Sotetseg Trainer

open source

Practice the maze without losing your loot.

RuneLite plugin that procedurally generates Theatre of Blood maze runs — built on the community-reverse-engineered algorithm — so players can drill the maze risk-free.

  • Java
  • RuneLite

Secret Share

hobby

Paste a secret, send a link, watch it self-destruct.

Web app for sharing credentials and sensitive data safely: paste a secret, get a one-time link, and the payload is destroyed the moment it's opened. Encrypted end to end.

  • TypeScript
  • React
  • E2E encryption

Homemade Transit Sign

hobby

A real bus departure board for the living room.

LED matrix sign on an Adafruit MatrixPortal S3 that fetches live TriMet arrivals and renders them like a station departure board, with WiFi diagnostics and a test suite.

Working on something where the product and the engineering aren't quite talking to each other yet? That's my favorite kind of problem.
