Leafly — Dual-Native Mobile App with Harness Engineering

In Progress
software

A plant-care application built with two fully native implementations: SwiftUI for iOS and Jetpack Compose for Android. Coordinated by a shared engineering harness that lets AI agents build both apps from the same specifications, business rules, and acceptance criteria — without sharing code.

Raúl Ferrer
Mobile Tech Lead and former iOS architect (author of *iOS Architecture Patterns*, Apress). After studying AI, I now focus on **Harness Engineering**: shared harnesses that enable AI agents to build dual-native mobile apps (SwiftUI + Jetpack Compose) with alignment, quality, and speed. I help mobile product teams multiply their engineering productivity.
