Selected work
Five things I designed, built, and shipped — products people pay for, and systems that keep themselves honest.
A live B2B SaaS with real subscriptions and a free trial — built and operated solo.
Helps tipped-industry employers track and document the “no tax on tips & overtime” deductions under the One Big Beautiful Bill Act — automatic Treasury Tipped Occupation Code assignment, FLSA overtime, W-2 Box 14 exports (ADP/Gusto/QuickBooks), an audit trail, multi-tenant role-based access, and an analytics dashboard.
Improvements are earned behind a 7-tier verification gauntlet — not hallucinated.
An autonomous system that improves its own code behind that gauntlet (parse, unit, property, mutation, benchmark, sealed holdout, fresh-context critic). A panel of specialized agents — planner, coder, tester, reviewer, critic — plus meta-improvement loops, all sandboxed.
The autonomous inner research loop is ported from Udit Goenka’s autoresearch (MIT, based on Andrej Karpathy’s work); the meta-improvement architecture and the verification stack are my own.
25 checks, 0 exceptions on a published report — the model never does the arithmetic; tested code does.
Turns a government audit statement (PDF) into clean structured JSON, then re-derives every total (foot, crossfoot, articulate) to prove the extraction is correct, with a golden-file regression test. No OCR for born-digital text. Inject one wrong figure and it’s caught.
Audit-ready 2 CFR 200 grant-compliance reporting, end to end.
Full-stack B2B SaaS that auto-categorizes nonprofit grant spending into 2 CFR 200 budget categories, tracks budget-to-actual per grant, and generates audit-ready compliance reports, with QuickBooks/Xero integration.
~3,000 lines of native C++20 — four distinct ghost AIs, co-op multiplayer, cross-compiled to an ARM handheld.
Built from scratch with procedural chiptune audio and sanitizer/coverage/strict build presets and tests.
