sporacle/

NFL decision service for the 2026 season. Calibrated win likelihood and fantasy projections served as static artifacts. The claim is calibration, not beating the market.

live / Python / DuckDB / LightGBM / Astro / Cloudflare

pixity/

Voxel city builder that started as one prompt to Opus 5.5 and grew into a full AWS build. Retired October 2026: deep, but thirty real days to a win.

archived / Three.js / Python / AWS / Terraform / Jenkins

diffeq-ti84/

Differential equations toolkit in calculator-constrained Python. Exact rational arithmetic, 921 tests, byte-budgeted builds sized for TI-84 Evo memory.

writeup only / Python

sdhub/

Structural dynamics solver on a TI-84 Evo. Closed-form vibration response with every step shown, 1,457 checks, and three memory failures found with on-device probes.

writeup only / Python

bd-1/

Life-size dynamically walking droid with fully local AI, currently in simulation and gait training.

in development / Python / MuJoCo / Stable-Baselines3 / Raspberry Pi / Teensy / ESP32

vex 5588c/

Four seasons of competition robotics: Maryland State Champion twice, and a VEX Worlds division win.

About

I like systems with constraints, whether that's a calculator with kilobytes of RAM, a CAD part that has to survive a printer bed, or a prediction model with honest error bars.

I interned at Skyward IT Solutions in Rockville, working on knowledge graphs, databases, and MCP servers for proposal support, and I'm staying on part time working on government solutions.

When I'm not building something, I'm golfing, playing guitar, or out with a camera.
