CKPT‑0000Ideated in Kenya

Nairobi, Kenya

Initialized from scratch. Curiosity, a very slow internet connection, and a habit of taking things apart to see what was inside — the pretraining corpus for everything that came after.

CKPT‑0300Pretrained in Connecticut

Choate Rosemary Hall

2018 — 2021

High school diploma, and a first real pass over a broad dataset: first lines of code, first taste of building for other people, built the entrepreneurial mindset.

Where the weights are running

6 deployments so far, 2 of them still live — a company I founded, a company I run engineering for, finance automation inside a Fortune 500, and four years of teaching and research.
