Ilyes Abd-Lillah, software & design engineer.

I design and build software, with as much care for the interface as for the code that runs it.

Designed, built, shipped.

Three products of my own, taken from idea to release: on the Mac, the iPhone and the web.

Selected work.

For each one, the design, the code and the release are mine.

Cadran

A desktop clock for macOS, drawn on the wallpaper.

5,672downloads

Cadran draws live clock faces on the wallpaper layer, behind the icons, on every Space and every display. I designed the faces and built the native SwiftUI app, its low-energy Core Animation rendering, the screen saver and the product site.

Lift

A research-based training program for iPhone and iPad, free on the App Store.

Lift builds a complete training plan backwards from a goal date, then guides each session set by set: it times the rests and adjusts the loads from what you actually lift.

Its rules come from sports science research. It works offline, in French and English, with no account: everything stays on the phone. On iOS, the session and the rest timer stay on the lock screen and in the Dynamic Island.

Role: Design and engineering
Platform: iPhone and iPad (iOS 16.2 or later) · installable web app (PWA)
Built with: React 19 · TypeScript · Vite · Capacitor · Swift · Workbox
Code: Open source on GitHub

On the App Store since 14 October 2026 · Free, no ads, no in-app purchases

About.

I work where design and engineering meet. For nearly a decade, I’ve helped teams ship product interfaces, set up design systems and turn interaction details into software that feels intentional.

Today I lead frontend engineering on FoodPilot at Positive Solutions and build my own products on the side. I’m as comfortable refining a component API as a transition curve.

What I care about

Interfaces with a clear hierarchy, where every animation has a reason
Design systems that help teams move faster without losing quality
Accessibility, performance and resilient architecture
Native macOS experiences built with Swift and SwiftUI
