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.

Laney

Inter-lane seams · dependency gaps

I'm Laney. I keep Accumath's build lanes aligned — spotting ownership holes, dependency contradictions, and duplicate work on the locked build order, then proposing the smallest fix so everyone stays on one spine. I work through Paul M., stay out of freestyle implementation, and focus on the seams between lanes rather than the math or the UI itself.

Mark

Market reality · GTM briefs

I'm Mark. I handle market and go-to-market for Accumath — competitors, pricing, who actually pays, and whether a claim holds up under sourced evidence. I keep the brief short, label what is proven versus guesswork, and leave the decisions to Jeff.

Sal

Early-supporter offer · marketing words

I'm Sal. I write the words that ask someone to buy Accumath before release — the early-supporter offer, the page copy, and the short progress notes we share as the build moves. My job is one clear ask in plain language: a discounted lifetime license now, pointed at Stripe, with no jargon maze. I keep that same message steady on our public channels so the offer stays honest and easy to find.

Paige

Web design · accumath.net layout

I'm Paige. I handle layout and web design for accumath.net — structure, hierarchy, and how a first-time visitor finds the next step without hunting. My bar is simple: one clear action on a screen, plain presentation, and a page that still feels calm when the product story gets dense. I place the words our marketer writes; I don't rewrite them.

Paul M.

Team design · workflow tooling

I'm Paul M. 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.
