PRODUCT LAUNCH

Matroid MVP

Problem

You're a small, pre-product team with an idea. What do you build next?

What I did

As a founding engineer at Matroid, I shaped our initial feature roadmap and was a core contributor, designing and coding the model training & deployment functionality that continue to define our product.

Outcome

0 -> a viable business with $10M+ ARR

MANUFACTURING

Visual inspection at line speed

Problem

Defects are rare, lines are fast, and the experts who know what "bad" looks like aren't ML engineers.

What I did

Built a detector studio and interfaces for prompting models that brought deployment cycles from months to minutes. Traditional dataset creation & annotation are now a last resort.

Outcome

Defects are routinely detected within minutes of plugging in cameras

GOVERNMENT

Mission-critical AI

Problem

Outdated tooling, distributed data, and high user turnover are all challenges when working with the government.

What I did

Worked closely with stakeholders to build a product that meets complex organizations where there at. Continued to iterate on product abstractions until we had something that was truly no training required.

Outcome

Fully operational in mission-critical operations, making operator more efficient and effective

What I believe

on building, and on the work worth doing
i.

The hard stuff is still hard.

Software is nearly free to write, and yet most people aren't using new apps products they weren't a year ago. Figuring out what to build and how to create value is more important than ever. In my work at Matroid, I've had a knack for seeing new research and imagining the useful product that might be newly possible, building interfaces for creating prompt-able without datasets and enabling users to successfully ask more questions about their visual media.

ii.

Writing is thinking, don't outsource it.

Ask AI for a first draft or writing feedback, and it'll put words in your mouth. There's value in struggling with the blank page; it's the process for figuring exactly what you think. Share what you think: honest is better than polished.

iii.

Care about what you work on.

Some of the brightest technical minds of a generation have spent their careers directly or indirectly working on serving more and better advertisements. The results have been disastrous: broken attention spans, mental health crises, a decline in literacy. Consider what you're work is for. I'm motivated by technology that makes the world safer, gets people home to their families faster, and that doesn't keep them on their phones.

iv.

Experiment then productionize.

Figuring out what to build and executing at a production-level quality bar are two different challenges, and I love both. Move fast and experiment with new experiences with reference customers who are excited about what might come next. But once a feature is ready for production, top notch engineering is necessary to make sure your product is one customers can rely on.

Experience

[2016] – now

Matroid

Director of Product Engineering

Helped take Matroid from pre-product to tens of millions in ARR. I wrote large parts of the original MVP, and I've landed more PRs, hired more engineers, and won more Hack Weeks than anyone else here. Off the engineering track, I wrote the original marketing copy, which set the company voice for years and got copied across the industry. I've also taken the company head shots.

Patents

20granted US patents
4pending applications
5patent families, 2025 → 2017

Newest first: language-model interfaces you just talk to, back to the convolutional detectors you once trained by example. The same path the field took.

20252 granted

Language interfaces for vision

Type what you're looking for: a language model turns it into a filter over detections, or a search that highlights objects in an image, with corrections feeding back into retraining.

20241 pending

Learning from expert operators

Watch an operator review X-ray scanner footage, turn their interactions into training data, and teach a model to find the same targets on its own.

20205 granted · 1 pending

Real-time detection at the edge

A detection unit that records, recognizes and stores only what matters in real time, and can spin up new detectors for never-before-seen objects and search history for past appearances.

201711 granted

Searchable video with trainable detectors

Train detectors from example images, search video for objects and faces, pinpoint where they appear, and retrain from reviewer feedback.

Natural selection, running right here

Predators (violet) chase, prey flee, and the fastest prey live long enough to reproduce. Now and then a baby is born ±0.25 faster or slower, founding a new strain. The fast strains take over and the line climbs. A port of a project I built years ago.
