Ray Yacub

At Hilton Worldwide, I led the Digital Key Android domain and delivered AutoUpgrades and Digital Key Sharing for the Hilton Honors app, contributing to a 15% lift in user engagement across millions of active users.

I drive Android platform modernization through Kotlin, Jetpack Compose, modular architecture, and accessibility-focused reusable component standards. I also partnered across engineering, product, design, and QA to guide architecture decisions, feature delivery, and feature-flagged Qualtrics analytics rollouts.

Previously at Ford Motor Company, I delivered FordPass and Lincoln Way features for millions of global users, including Pickup & Delivery, which reached more than 100K users in its first year. I helped migrate legacy Java systems toward Kotlin and RxJava2, while championing TDD, pair programming, and continuous delivery workflows that reduced production defects by 25%.

My earlier work includes improving smart-home app startup time by approximately 40%, supporting five healthcare applications as the sole Android engineer, and building real-time voice recognition and AES encryption solutions for aviation workflows. I enjoy setting engineering standards, mentoring developers, and building scalable mobile systems that solve business-critical problems.
