Aadi is a design engineer at Ownpath building AI tools, shipping for Philips, Hero MotoCorp and Koolio, and sweating the last 10% of every interface.

I lead engineering for Ownpath’s clients and build AI tools for our designers. Along the way I’ve shipped a health PWA for Philips, the apps Hero MotoCorp took to EICMA in Milan, and a browser audio editor for Koolio. On the side I build AI MVPs for early-stage startups, and open-source AI agents for myself.

01 / Client work

Shipped with Ownpath, for Philips, Hero MotoCorp and Koolio.

At Ownpath I lead engineering for enterprise clients across healthcare, automotive and AI, from these three to the motion work on Realfast AI’s site, and I build AI tools for our designers. Each one below is rebuilt in miniature, so you can use it instead of reading about it.

Ownpath × Hero MotoCorp / Lead developer, design engineering and AI

EICMA 2025, Fiera Milano

Apps for the world’s largest motorcycle show.

Through Ownpath, I was the lead developer for the apps Hero MotoCorp showed at EICMA in Milan. Ownpath’s design team and Hero’s own drew it; I built it, and tuned every transition until it held up on the show floor.

Ownpath × Philips / Lead engineer

Heartprint. A heart check that takes one finger.

I rebuilt Heartprint from the ground up as the sole lead engineer: a health PWA that reads your vitals through the phone camera, on Philips’ SDKs. The redesigned onboarding and scan flow beat the original app on retention and satisfaction.

Ownpath × Koolio.ai / Lead frontend engineer

Koolio. Editing audio like editing a doc.

I built the product from scratch with the whole audio engine in the browser: waveform rendering, transcript-based editing, FFmpeg on the client. It syncs to the backend in intervals, so no edit ever waits on the network. Used by thousands of creators.

02 / AI

I build AI for the boring parts, so designers get back to the work they love.

Right now that means AI tools for the designers at Ownpath. It has been the thread for years: an LLM tutor that got acquired, AI design tools for Hero MotoCorp, AI MVPs for early-stage startups, and coding agents I ship as open source.

03 / Products

After hours, I make my own tools.

Open source, mostly for the Mac. Every window below is running, so go ahead and drive them.

Graphe · macOS app 2026

Graphe. Send in a team, not a prompt.

An open-source agentic coding platform for the Mac. Helpers run in parallel, jobs keep working for hours without you, and an agent reads your design system before it writes a line. Built on pi, local-first, your keys and any model.

Rune · Command line 2026

Rune. A coding agent harness in 3 MiB.

A tiny native coding agent harness written in Rust. About 3 MiB and 2 ms to start, model and provider agnostic, no daemon, no telemetry. Apache-2.0.

Sift · macOS app 2026

Sift. Email that keeps up with you.

A keyboard-first Gmail client for Mac that mirrors your mail to your own machine, so search is instant, reading works offline and the inbox finally feels calm. Rust core, no server, MIT licensed.

Cursor Gallery · Web registry 2026

Cursor Gallery. Cursors that command attention.

A registry of 100+ animated cursors for shadcn/ui. Each one engineered with Motion, tuned for performance, and one command away from your project.

Open source

Taste is ancient. The tools are new.

Two thousand years between the chisel and the pen tool. The eye that knows when something is right has not changed. I just get to work with both.
