Software engineer · Producer & DJ · Audio software
Full-stack engineer with 10 years shipping payments, marketplaces and integrations, and an AI-native workflow that multiplied my output. Off the clock I produce and DJ as Coastlines, playing and selling tickets to my own shows in New York and across the US.

Experience
Building music-production plugins for Ableton Live in C++/JUCE by directing AI agents: four plugins and ~60,000 lines of real-time C++ in under four weeks, shipped with CI, render tests and a signed installer.
Led complex features end to end on a multi-tenant platform for car dealers: card and ACH autopay, an insurance-compliance product, most of a React/TypeScript UI redesign, and the performance and security work behind them.
Built payment systems on blockchain rails, including a production application on Google Cloud and Stellar that carried $100M+ in transactions, and helped build a digital-dollar platform to replace SWIFT.
Built a direct-to-consumer drinks brand from zero: raised about $600K, won federal TTB approval and shipped to 30+ states.
Founded a subscription clothing-rental marketplace and led a team of 5 building it on React, serverless AWS and Stripe, reaching 60 subscribers in the first month.
Built ML classification models and validated transaction-monitoring and sanctions-screening models for large financial institutions.
I’m a problem solver first. I start from where we need to end up, find the real problem behind the obvious one, and look for the simplest, sometimes unexpected, way there.
I begin with what done looks like: the outcome, how we'll know it worked, the one rule that can't break, and how we'd undo it. Then I work backwards to the design.
In practiceThe autopay rebuild was planned backwards from “no customer charged twice”: a shadow run beside the old engine, a kill switch and a rollback at every phase.
Before fixing anything I measure it or prove it. The obvious answer is often wrong, and the real one is usually simpler.
In practiceA collections screen took ~9 s. Measuring showed per-row queries, and batching them put rows on screen in ~80 ms.
A written spec, then a clickable prototype people can react to, then the build. Questions get settled while they're cheap.
In practiceThe insurance integration went from spec and Storybook prototypes to merged code in ~5.5 weeks.
Payments, music and collectibles keep teaching each other. The best solution is often a pattern borrowed from somewhere else.
In practiceA limited collectible drop and a limited ticket drop are the same problem: each one has to sell exactly once, and I proved that with concurrency tests.
Complexity has to earn its place. When a design gets heavy, I step back and ask what the goal actually needs.
In practiceI steered an over-built engine to a simpler design: 574 lines removed and merged the same day, and 16 obsolete tickets closed.
AI writes most of my code under rules I wrote. I decide what to build, verify what it claims, and own the risky parts.
In practiceWhen the AI kept misdiagnosing a production incident, I proved from build hashes in the logs that production was two weeks behind.
Interactive · doug audio
Four experimental synth engines from my plugin lab, rebuilt to run in your browser. Every sound is made from individual harmonics in real time: no samples, no reverb. Pick an engine and press Hear it, or play the keys.
A web recreation of warm lab from doug audio (C++/JUCE): the plugin’s own core shader in WebGL and a few of its factory sounds, with the engines rebuilt for the browser in an AudioWorklet. On iPhone, turn off silent mode to hear it.
Interactive · packrip-go
From a collectibles marketplace I built in Go and Postgres: vaulted items, a marketplace with fees and payouts, and limited drops that can never oversell. Every item is drawn in code, so tilt it toward the light.
In the real app (Go + Postgres), every pull is a vaulted item with a ledger entry, and concurrency tests prove a listing sells exactly once. This demo runs in your browser with invented items.
Music
Melodic and progressive house. I produce, DJ, and play and sell tickets to my own shows in NYC and around the US, so I know the organizer’s side: promoting the night, selling the tickets and bringing the crowd back.
