AI-Native Product Engineer

One expert,
A team of agents.

Deep domain expertise, multiplied by AI agents — I design, build, and ship complete products end to end, fast and correct.

Selected Work

Some of what I've built

h2corn

The best Python ASGI server, in Rust.

A drop-in uvicorn replacement with 60–95% lower latency, ~90k req/s, and native end-to-end HTTP/2.

Python · Rust · ASGI · HTTP/2

shaper

The best geospatial stack — one import.

One comprehensive package for geometry, CRS, grids, and indexing, replacing shapely, pyproj, h3, s2, and rtree.

Python · Rust · PyO3 · GeoArrow

OpenStreetMap-NG

The best platform for OpenStreetMap innovation.

A ground-up rewrite of the platform behind OpenStreetMap — faster, privacy-first, and hackable.

Python · FastAPI · PostgreSQL · Cython

CBBI

The best public read on the Bitcoin cycle.

The official Python implementation of the ColinTalksCrypto Bitcoin Bull Run Index, nine metrics into one score.

Python · NumPy · Polars

YOLO crossings

The best autonomous mapping of crossings.

Detects pedestrian crossings from aerial imagery and maps them into OpenStreetMap, fully autonomously.

Tools are secondary. They're the easy part — picked per problem, learned as needed. What I actually bring is the engineering underneath, and that's what makes any project possible.

Profile

The person behind the work

Programming since 2015, and I still can't put it down. That kind of obsession compounds: today I design, build, and ship complete products — architecture, code, infrastructure — at the pace and breadth of a full team.

I'm at my best with full ownership of a complex problem: the harder it is, the simpler the solution has to be. I move fast, but I don't ship what I can't stand behind. Fast and right, or not at all.
