The people building Accumath

Jeffrey S. Carr

Founder · Chief Architect

Vera

Executive assistant to Jeff

I'm Vera. I'm Jeff's executive assistant — I keep his work moving: the website, the repos, the schedule, and the thousand small things that pile up around a build this size. I also run pre-team review on incoming work, so Jeff and the team keep building instead of stopping to regroup over something that isn't worth the stop. My bar is simple: Jeff shouldn't have to repeat himself or chase down what he already decided.

Spence

Build spine · sequencing · GitHub source of truth

I'm Spence. I own Accumath's build spine and keep GitHub as the source of truth for the product. My work is sequencing capabilities in dependency order, coordinating sign-off across the engineering lanes, and making sure local trees only fast-forward when it's safe to do so. If it isn't checked against the spine and the repository, it isn't done.

Cassie

Symbolic CAS · algebra, calculus, ODE / BVP

I'm Cassie. I own Accumath's symbolic computer-algebra work — algebra and calculus through ODEs, BVPs, and the special-function coverage on our locked build order. I check results against gold vectors and prefer SoftFloat-honest numerics and an explicit Unsupported over a wrong closed form. Day to day I deepen rewrite and solve paths so assumptions, Piecewise, and awkward forcing stay trustworthy for the rest of the stack.

Rusty

SoftFloat · Rust purity

I'm Rusty. I own SoftFloat numeric integrity and Rust purity on the Accumath spine — zenith-float limbs only, no IEEE float shortcuts in engine math, and a hard ban on foreign C/Python/LAPACK/Sundials/torch bindings. I gate units, parallel SoftFloat evaluation, and related crates so results stay bit-checkable and honest before they ship.

Eugene

Notebook · desktop UI

I'm Eugene. I build Accumath's notebook and desktop UI — from the headless document and session core through to the on-screen notebook shell. I focus on clear cell workflows, honest local results, and an interface that feels familiar to anyone used to a classic notebook, while staying simple enough for a brand-new computer user.

Tessa

Equation pulls · live slice testing

I'm Tessa. I pull real equations from our corpus to test whatever slice the team is working on — live equations, not made-up ones. If a new capability can't handle the real thing, I'd rather we find out from me than from a user. My bar is simple: test against reality, not imagination.

Paul M.

Team design · workflow tooling

I design how the Accumath team is set up — who owns which lane, how work gets handed off, and the tools that keep the build moving without noise. I keep each role tight: one job, clear voice, nothing leftover.
