I. QUANT
LIVE · 2026 · quant.mmmxcix.com
An independent quant research desk. Backtests that are deflated for how many ideas were tried, walk-forward validation, purged cross-validation, and a strategy engine that keeps its own failures on the shelf next to its wins.

II. CASINO
PAUSED · 2026 · casino.mmmxcix.com
A social casino: rooms, clans, VIP ranks and a set of original slot games built from scratch. Complete enough to play, parked while the desk takes priority.

Record
Gil Buholzer
Student · building things I want to exist · Switzerland
I'm still in school. Everything here started as something I wanted to exist and couldn't buy, so I built it — with AI doing the parts I haven't learned yet.
Right now it's a hobby. I'd like it to become more than that.
Nothing here is a mockup. Every project on the shelf is deployed, and it stays on the shelf whether it's live, paused or half-finished.

2018
Scratch, and a little HTML
and earlier
Block-based projects, then some hand-written HTML and CSS. Nothing at this scale — but it is where the habit came from.

JUN 2026
Casino
casino.mmmxcix.com
Rooms, clans, VIP ranks and original slot games, built from scratch — the first thing I built properly. Playable in a month, then parked for the desk.
-
JUL 2026
Quant Desk
quant.mmmxcix.com
A research desk that grades its own strategies honestly — and keeps the failed ones on the shelf. Still the main thing.
