CTO · Sydney

I ship products —
and the engines under them.

Chief Technology Officer across three companies — solar AI, equine welfare, residential energy. Outside that I ship two automation platforms for teams with a process and no engineer, and build renderers for the pleasure of it: WebGPU engines, voxel worlds, procedural planets, generated from nothing but code.

Companies I build and run

Three businesses, three domains everybody agrees are complicated. The job is the same each time: make the complicated part invisible to the person who has to make a decision.

  • Accurassi

    Live

    Chief Technology Officer

    Neural networks that read a roof and price the solar on it.

    Accurassi turns messy household energy data into offers people actually buy — the comparison and electrification engine behind retailers, distributors and government services. I build Solar Seeker, the AI that analyses roof structure to model solar and battery systems against a customer’s real consumption.

  • StableWizard

    Live

    Co-founder · CTO & CISO

    Welfare-first management for thoroughbred racehorses.

    Stables still run on paper and memory. StableWizard replaces that with continuous capture — devices feed a live dashboard, and a reading outside a horse’s own historical range raises an alert before a person would notice. Early virus detection, and longer racing careers.

    • Time-series analytics
    • Alerting
    • Role-based access

  • TogetherNRG

    Live

    Co-founder · CTO

    TED — cut a pool’s running cost without touching the pool.

    A pool pump is often the largest single load in an Australian home, and almost all of them run far longer than they need to. TED is a smart plug and app that works out how long the pump actually needs, schedules around weather and tariffs, and ties runtime to measured water chemistry.

Labs

Outside the day job

Two automation platforms first — FlowRunner and Trigata both hand a working process to a team that has no engineer to build one. Then the graphics: procedural renderers, almost all of it running in a browser tab, some of it built with my ten-year-old son.

  • FlowRunner

    Live

    Design pages. Run flows. Ship apps.

    A no-code platform where a drag-and-drop page builder and a visual flow engine publish straight to live HTTP endpoints. The visible half is a builder; the interesting half is everything required to execute someone else’s logic on your infrastructure without regretting it.

  • Trigata

    Live

    Process automation for people who do not write code.

    Structured data tables, custom forms, and trigger-based automations — send an email, call a webhook, run a scheduled job — behind fine-grained role-based access control. Aimed squarely at small-business teams with a process and no engineer.

  • Band Tutor Buddy

    Live

    Practice between lessons, for band kids.

    Notation and tab that plays back, listens through the microphone, and tells a kid whether they actually hit the note. Built for the gap between weekly lessons — where nearly all the practice happens and nobody is there to correct anything.

  • Forge3D

    Live

    A WebGPU game engine and editor that never leaves the browser tab.

    Open a tab, build a 3D game, export a single self-contained game.html you can double-click. Forge is a real editor — hierarchy, gizmos, inspector, TypeScript scripting — running on WebGPU with no install, no account, and nothing leaving your machine.

  • Procedural Planet

    Live

    A planet with no assets — and five different ways to compute it.

    A WebGPU planet renderer on a floating-origin coordinate system: terrain, cascaded shadow maps, atmospheric scattering and LOD, all generated. The simulation core is implemented five times over — C++, Rust, Go, C# and Zig — each compiling to WebAssembly behind one interface.

  • BlockWorld

    Live

    A voxel world where the terrain and the textures are both generated.

    A Minecraft-shaped technical study: how far a voxel renderer can be pushed without leaving WebGL2 and WebAssembly. A C++ chunk pipeline on a worker pool, greedy meshing, and 4×4 super-chunk batching for high view distance. No art assets — every texture is procedural.

  • Path Tracer

    Live

    Progressive path tracing in a browser tab, denoised.

    A physically-based path tracer with an SVGF denoiser. The denoiser is the entire point — it is what makes a handful of samples per pixel resolve into something that looks converged, instead of something that looks like sand.

About

Ciarán McCormack

Over twenty years of software engineering, most of it spent where product decisions and hard systems problems meet. I am the CTO of Accurassi, and a co-founder and CTO of both StableWizard and TogetherNRG.

The pattern across all three is the same: a domain everybody agrees is complicated — energy tariffs, animal welfare, pool chemistry — and a small team that has to make it feel simple to someone who did not ask for a lesson in it.

That instinct carries into what I build on my own time. FlowRunner and Trigata are both automation platforms aimed at small teams who have a process worth automating and nobody to write the code — take the thing that needs a developer, and hand it to someone who is not one.

The rest is graphics, for the pleasure of it. Procedural generation is the thread: worlds, planets, textures and terrain computed at runtime instead of shipped as assets, almost all of it running in a browser tab. Some of it I build with my ten-year-old son, which is the best reason I have for any of it.
