About

I’m an electrical engineer at Delta TechOps in Atlanta, where I build automated test equipment for avionics components. I work on every part of it, from the schematics and board layout to the test software, assembly and validation. I have a B.S. in electrical engineering from Georgia Tech.

Lately, most of my side projects have been math, mainly fast transforms and number theory. Several come with machine-checked proofs in Lean 4.

    TONER-1: a language model that runs inside a laser printer

    A 260,032-parameter language model packed into one 595 KB PostScript file. Send it to a laser printer, and the printer’s own processor writes and typesets a children’s story about printers. The computer that sent it does none of the math.

    wht-fewer-operations

    Circuits for the Walsh–Hadamard transform that use fewer operations than the textbook method, with Lean 4 proofs of the operation counts. On an FPGA they need fewer logic cells, but on a processor they save only a few percent of run time at best. I directed the work, and AI agents (Claude Opus 5.5) wrote the code and proofs and ran the searches.

    sieve-ceilings

    In 2021, Jori Merikoski proved that infinitely many primes have the form x² + (y² + 1)². His proof finds at least 60% of the expected number, counted with his weights. This paper shows that the same estimates give at least 96.36%, and that 96.36% is the most they can give in Ford and Maynard’s model. I did the work with AI agents (Claude Opus 5.5), and a separate agent checked each step by trying to break it.

    qrh-zero-free-bounds

    On the Quasi-Riemann Tracker, people are working to lower θ, the boundary past which no Dirichlet L-function can have a zero. My Lean-checked bound, θ = 0.8739558, was merged and stayed the tracker’s best for most of a day, though others have since gone well below it. The repository also maps 66 dead ends for anyone going after a bigger improvement. I did the work with the help of AI agents (Claude Opus 5.5).
