Open to technical & creative roles

Curious by default.
Built to figure it out.

Creative technologist, problem-solver, audio engineer. I notice the thing nobody else is looking at, sit with it until it makes sense, and build something useful out of what I find.

About

who I am, in plain language

A curious, self-driven builder with an unusual combination of backgrounds — creative tech, audio engineering, and the factory floor.

I studied Creative Technology at Illinois State University — a program built exactly for people like me: hybrids who don't fit cleanly into "designer," "engineer," or "artist" because the interesting work lives between those categories. Since graduating in 2021 I've spent every year deepening that range.

Before any of the technical work, there was sound. I've spent years engineering, producing, and mixing — from vocal sessions to livestream boards to late-night freelance gigs. Audio is the discipline that shaped everything else: the patience to listen for the problem nobody else is hearing, the taste to know when something is actually finished, and the humility to stay with a track until it's right. Those instincts didn't go away when I moved into other work. They're how I approach every technical problem now.

Over the last two years at Rivian, I've learned what production actually looks like from the inside — what breaks, what drags, where good people end up doing work a computer should be doing. When I rotated onto the Autonomy team, I didn't just do the work assigned to me; I found a repetitive task in the workflow and built a tool to solve it.

That combination — creative ear, engineering instinct, real operational experience — is what I bring. I'm a builder who teaches himself whatever the problem demands, ships something, and iterates until it's right. I've done that in studios, on the line, and on my own time.

Proof of Work

what I've actually shipped

Rivian Autonomy — custom workflow automation tool

Built · Proven

Hired onto Project Annotate to do high-volume image annotation for Rivian's autonomy training pipeline. Noticed a repetitive sub-task in the workflow that nobody had automated. Built a custom macro tool on my own initiative, measured the results, and documented the gains.

The data spoke for itself — 3–7× throughput at 99.9% accuracy, depending on task content and fluency with the tool. It became my personal force multiplier on the team. Recognized with Rivian's Employee Recognition Award (January 2025) for operational excellence.

01 / how I work

Notice first, build second

I watch the workflow closely before I touch anything. The right problem to solve is almost never the one on the whiteboard — it's the one people have stopped complaining about because they assume it's just how things are.

02 / what I bring

An engineer's patience, an artist's ear

Years behind a mixing console taught me to trust my gut on when something is "done" — and when it isn't. I bring that same discernment to technical work: a willingness to sit with something until it's actually right.

03 / why it works

Translate across worlds

I can read a factory lead, a software engineer, and a studio client in the same week without losing anyone. That range is rare, and it's the reason the things I build actually land with people.

Case Study

// MacroBox · the annotation tool
MacroBox — a tool I built to do my own job faster.
Built · Deployed · Measured

Project Annotate ran on a high-volume repetitive workflow — the kind where good people burn out doing work a computer should be doing. I built MacroBox, a configurable Windows macro utility that records, replays, and binds repeated input sequences to single hotkeys. It's the tool I ran every day on the Rivian autonomy pipeline.

01 · the problem

A repetitive sub-task hiding in plain sight

The annotation workflow required the same handful of input sequences over and over — the kind of pattern that's imperceptible on day one and painful by month two. Nobody had automated it because it wasn't officially part of the job to fix.

02 · the approach

Record once, replay precisely

I designed a simple mental model: every sequence I ran more than three times should be a hotkey. MacroBox records raw input with exact timing, saves it to a named slot, and rebinds it to a key combo or numpad shortcut I won't confuse with real work.

03 · the build

Built in AutoHotkey, tuned for the floor

Stopped myself from over-engineering. AutoHotkey was already on the machine — no install, no dependencies, no permissions fight. Added Record / Stats / Config / Break / Wide / Clear controls, live visual feedback per slot, and a STOP combo so it never runs when I don't want it to.

04 · the result

3–7× faster in practice — measured, not claimed

Same sequence, same accuracy. Measured gains vary from 3× to 7× depending on the repetitive content of the task and the operator's fluency with the tool — my demo clocks in at 4.75×. Across a full shift that compounds into hours of reclaimed focus. Recognized with Rivian's Employee Recognition Award (January 2025) for operational excellence.
