Take it to the limit, then delete the rest.

Mathematician and data engineer. I run regulatory data at national-bank scale, and I write neural nets in C to make sure I still understand what’s underneath.

01 — what I’m good at

Pipelines, end to end

Ingestion to regulatory output, owned rather than handed off. FINREP, COREP, SIRBE, stress testing — filed, reconciled, defended.

Debugging by disaggregation

Split the thing until each part is small enough to be obviously right or obviously wrong. It has never failed to find the bug.

Removing the non-essential

I like systems pushed to their physical limits with the redundancy cut out — and AI used hard as part of how the work gets built.

02 — ask this site

Interview the page instead of reading it.

It answers from what I’ve actually built and shipped. If it doesn’t know, it’ll say so.

Unfinished on purpose. If you have an answer, or a better question, I want to hear it.

Q1
Is a decentralized civilization feasible?
Not the token — the civilization. Governance, defence, and the logistics nobody writes whitepapers about.
Q2
What is true, versus what you are told?
The gap between the account and the event, and whether you can measure it.
Q3
Can the Collatz conjecture be read as linear algebra?
3n+1 and n/2 as matrices, hunting invariants. Unpublished — ask me.
Q4
How big a sofa fits around the corner?
A soft actor-critic agent versus an L-shaped corridor. Geometry by search.
