I build systems that measure — then I listen to what they say.

Shift-invariant signal processing, deterministic generative engines, and software that keeps running when nobody is watching. Engineering and mysticism are the same question asked twice: what is actually there?

Three questions, measured honestly.

Shifted Collatz kernels & the hybrid ensemble

signal processing · statistics · 2025–26

Collatz stopping times follow a log-normal distribution. Treated as convolution kernels, shifted along that distribution, they give a filter bank that is topologically deterministic — the same input always yields the same output, with no learned weights.

Assembled into a hybrid ensemble, the corrected filters measured 2.9 × on texture retention and 2.0 × on signal detection against the uncorrected baseline.

Press launch, or hit space. Every number falls to 1 eventually — the question is how long it takes. Runs are logged below, best and worst remembered.

    Arrhythmia classification on SPARC-ECG

    biomedical · deep learning

    Multi-class arrhythmia detection over the SPARC-ECG corpus. The headline accuracy figure is the easy number to quote and the easiest to be misled by, so it is not quoted here: on the class-balanced view the model reaches a macro-F1 of 46.89%, and that is the number this work stands behind.

    Hardware-side results were verified under emulation, not on physical silicon — stated plainly because the distinction matters.

    Hybrid smart microgrid

    power systems · EEE-202

    A solar-plus-grid controller with live instrumentation: generation, storage, load and switching modelled end to end, with the dashboard as the only interface that matters — if it cannot be seen, it cannot be trusted.

    Atlas

    autonomous Android agent

    An on-device agent that drives a phone the way a person does — reading the screen, deciding, acting. Published with a tagged release and a demonstration run.

    IRIS

    deterministic procedural webtoon engine

    A comic engine that generates panels, faces and lettering from parameters — deterministic, SVG-first, no diffusion model anywhere in the pipeline. The same script yields the same page, every time.

    a world, in Unity

    A navigable world and the writing that grew out of it. Keeper and companion rather than examiner — the world is not dissected, it is inhabited.

    Hermes stack

    agent orchestration

    A board-driven multi-agent system: task queues, scheduled autonomy, browser and desktop control, and a monitoring dashboard — running unattended on a headless Linux node around the clock.

    private health analytics

    Longitudinal blood-pressure analytics that runs entirely on local hardware. Nothing leaves the machine — which is the whole point of it.

    local video engine

    An offline editing and rendering pipeline with beat-synced cuts and cinematic titles — driven by agents, rendered on consumer hardware.

    04 — Method

    Rigour over breakthrough.

    A breakthrough is a claim. Rigour is the apparatus that decides whether the claim survives. I build the apparatus first.

    Almost every figure on this page was revised downward before it was published. The classifier that looked like 95% is quoted at 46.89%, because class imbalance does not care how good the number felt. Results verified in emulation are labelled as emulation. Systems that cannot be observed are treated as systems that do not work.

    The same discipline runs through the other half of the work. Engineering and mysticism ask the identical question — what is actually there, once you stop wanting it to be something else? One answers with instruments. The other answers with attention. Neither is complete alone.

    Build the measurement before the claim, and you only have to be honest once.
