Building
Remanence pipeline
Digitizing analog reels and wiring up the local agentic system that turns raw audio into searchable archive pages.

Engineer who
builds with
the machine.
I design and ship spatial interfaces, digital twins, and AI-driven applications. Frontend by day, full-stack when the problem asks, and somewhere between an instrument and a system on nights and weekends.

Playing with
Browser instruments
Sequencers, tape-loop behavior, granular textures, and small interfaces that make sound feel physical.
Available for
Frontend + AI systems
Spatial interfaces, platform work, workflow design, and teams that want one engineer who can own a lot of surface area.

How I work.
01
The premise
Fluent in TypeScript, Java, GraphQL, and Mapbox — but I treat language and framework boundaries as largely irrelevant in an era of agentic development.
02
The workflow
A disciplined, iterative loop between human judgment and machine execution that consistently produces production-quality output across the full stack.
03
The output
Modeling complex spatial systems, reasoning through pipelines, evaluating distributed tradeoffs, and building UIs that make difficult things feel simple.

Remanence Archive
Archive · Pipeline · 2025 · Active build
A web home for the analog reels I’m collecting and digitizing. The site is the polished surface; behind it runs an agentic pipeline — Go orchestration, Whisper.cpp, Claude — that handles transcription, summarization, metadata, and publishing end-to-end.

Project Sonorous
Sound · Web · Plugins · 2024 — · Active build
An interactive sound playground and home for the audio plugins I release under the same name. Planetary sequencer, granular synth, tape-loop emulator, Markov sequencer, and more in flight. An honest example of what AI changes about creative engineering: dream up an idea in the morning, have it playable in the browser by afternoon.

Nights & weekends · Swift · 2025 — · Reelay live · more in flight
A growing shelf of native iPhone apps I design, build, and ship solo. Reelay — a movie club for your group — is live on the App Store; alongside it are sound instruments and tools: Tape Death, Aural, and Rebrew. The through-line is small, opinionated apps where a little craft goes a long way.

Off the clock.
Husband. Girl-dad to two daughters — three years and five months. The house is loud, full of toys, almost always tuned to whatever song my oldest is currently obsessed with.
Outside of family and work I make music. Mostly guitar and piano, plus an ever-growing pile of synthesizers and tape machines I keep wiring into something else. A lot of my side projects live at the seam between sound and software, which isn’t accidental — I’m happiest when an instrument and an engineering problem turn out to be the same thing.
