Things I'm building, things I've published, things still running. The content IS the product. The trading IS the proof.
Things that are running right now and you can use today
Offline AI voice diary, 100% on-device
A free voice journal that builds your Digital Twin without ever leaving your iPhone. No accounts, no cloud, no tracking. Voice-to-LLM, all local. Also where I'm experimenting with running a real LLM on a home machine — closing in.
Limit order book + matching engine, in Go
An embeddable central limit order book — integer-exact pricing, one goroutine owning the book with no lock on the hot path, and crash recovery gated in CI. It compiles to WebAssembly, so the demo, the six-chapter tutorial and the live console are the real engine running in your tab, not a drawing of it. MIT on GitHub.
Free hands-on course — how LLMs actually work
Six sessions from "what's a token?" to a shipped app. Built for TCE Madurai, free for everyone. Opens with a 3Blue1Brown-style visual walkthrough of how GPT works — neuron to transformer — plus a hands-on playground where a real model trains in the browser.
Voxel building & survival game, made for Adyah
A voxel sandbox built from scratch for my son Adyah. Custom WebGL engine, no game libraries. Build, survive nights, fight mobs, find 5 golden stars. Saves locally. Runs in any browser and as an Electron desktop app.
Published with Packt, 2018. Code repos still maintained.
TensorFlow Lite + Core ML, end-to-end
Project-driven guide for shipping ML on iOS and Android. Age + gender CNN, neural style transfer, ML Kit (text/face/barcode), Snapchat-style face filters with OpenCV, MNIST adversarial classifier, on-device food classification via transfer learning.
Concept-first companion to Mobile AI Projects
The mental-model book. Demystifies the mobile ML landscape — toolchains, deployment patterns, on-device vs cloud tradeoffs, what to use when. Pairs cleanly with the projects book if you want both the why and the how.
Older builds — Teleport Call (GazeMatic) is the one that hit hardest.
VR voice calling — 420k organic downloads
Founded GazeMatic in 2014. Built Teleport Call — a first-of-its-kind VR voice-calling app where two callers could meet inside a shared virtual environment. 420k+ organic downloads in the first month, 1.2M+ calls placed across US/UK/Germany/Russia/India. Zero paid marketing. Ran for 4 years before winding down.
