McDonald’s meal ordering mobile application for 65+ markets
The challenge is to build a highly configurable, market-agnostic platform that supports: local regulations & compliance (tax, privacy, age restrictions), multiple order fulfillment models (delivery, pickup, dine-in), diverse payment methods (from credit cards to local wallets), regional menu variations & languages.
The design has to balance global scalability with local flexibility, ensuring that every customer — from Stockholm to Hanoi — enjoyed a consistent, seamless, and culturally relevant experience.

A significant part of my contribution has been building, adapting, and scaling the design system to ensure consistency, accessibility, scalability, and support for dark mode across iOS and Android. This work allowed the team to move faster, maintain a unified brand experience, and roll out updates confidently across 65+ markets.
Communicationa and collaboration are the keys. I’ve worked closely with cross-functional teams — including developers, project managers, stakeholders, and fellow designers — refining flows, preparing dev-ready handoffs, presenting solutions to clients, and collaborating daily through Slack and in person. I also partnered with the analytics team to plan A/B tests and uncover opportunities for validation and continuous improvement.
One of the most impactful moments in this journey was contributing to the full redesign of the app. Six months after launch, the results spoke for themselves:
