Tools &
Design

I build software for the organizations I run — an orchestra, a publishing house, a foundation — and design sites for other arts, healthcare, and nonprofit teams.

None of this started as a software business. It started with problems nobody sold a fix for: cataloging orchestral works with real instrumentation data, keeping books current across several small organizations, delivering digital sheet music reliably.

So I built the tools, mostly with AI assistance, and ran them in production on my own operations first. Some of them grew into products. The rest of the practice is design work for organizations like the ones I run.

Built & Operated

Products

Sage

Accounting Automation

In private use

A QuickBooks Online–connected app that keeps small-business books current: transaction categorization, review workflows, and reporting. Built because I needed it for my own companies' books; it now runs them daily.

OpusGraph

Ensemble Music Library Management

Public

A platform that helps orchestras, choirs, and bands catalog their sheet music, track parts and copies, log performance history, and plan seasons — replacing the spreadsheets most libraries run on. A curated classical music reference database auto-fills instrumentation, duration, and publisher as you catalog, and natural-language repertoire search is in development. Built to answer a question I kept hitting as a conductor: what exists, and what does it take to perform it?

AgentMeter

macOS Menu Bar App

Shipped · Open Source

A tiny macOS menu bar app that keeps AI coding usage limits visible at a glance — Codex, Cursor, Claude Code, Gemini, and more — with detailed meters and reset countdowns. Built because I work across all of them daily and kept getting surprised.

FelixOS

Personal Operations System

Personal · Internal

A personal operating system for running my work and organizations — tasks, calendar, email context, contacts, projects, and notes — with a server backend and web, iOS, and macOS clients. It's also the proving ground: patterns get tested here before they show up in anything I ship.

Publishing Platform

Resonance Music Press Operations

In development

A commerce platform purpose-built for digital sheet music sales and rentals — catalog management, score delivery, and licensing and rental workflows in one system. I'm building it custom because, to my knowledge, no platform exists for this use case; the design comes from years of running publishing operations on general-purpose e-commerce tools and working around their limits.

Commerce Digital Delivery Rentals & Licensing

In development: CareLedger, an iOS-first, local-first pet-care ledger, and a family of Spanish–English apps for bilingual households.

Selected Work

Web Design

Services

Web Design & Development

Custom websites built with modern frameworks — from single-page sites to platforms with authentication and databases.

Internal Tools & Automation

The unglamorous software that keeps small organizations running: bookkeeping workflows, document generation, digital delivery, integrations.

Brand & Visual Identity

Cohesive visual systems across digital touchpoints — logo, typography, color, and component libraries.
