context
Founded in 2013, Mondly was one of the first language learning apps on the market. In 2022, education giant Pearson acquired Mondly as part of their strategic expansion into digital products.

To modernize the platform and compete in today's market, Pearson began hiring new product and design talent—which is where I came in.

I joined Mondly in 2023 to co-lead a complete product redesign. When the lead designer departed, I became sole owner of the redesign—managing everything from research and design system creation to developer handoffs.
After successfully launching to millions of users, I transitioned to leading the Learning Experience squad, directly impacting key metrics. As we expanded the design team, I was promoted to Design Lead for the entire B2C product, overseeing the complete app experience.

Learning Experience Leadership
As a learning experience designer I own all core learning mechanics that drive Mondly's business: interactive quizzes, conversation exercises, and vocabulary training systems. Through systematic A/B testing and iterative design improvements, we've achieved double-digit improvements for our key metrics in just two quarters.

We optimized all 25+ quiz types for multiple device sizes and languages, including right-to-left scripts like Arabic. Added haptic feedback and intuitive motion design that enhances engagement without breaking concentration. These technical improvements, combined with performance optimization for low-end devices, transformed underperforming features into key retention drivers across our global user base.

Vocabulary Review
My squad has built Mondly's most-requested feature - vocabulary review. We have been following a very lean approach with a barebones MVP, where users were just able to review words and phrases from the lessons, and save them in the 'saved' folder.

With each quarter, we're introducing richer functionality and we've seen triple digit positive change in feature engagement and discoverability since the first release.

Below you can see different stages of the Review section and our plans for the future.

Beyond the core work

//
leadership
Mentoring cross-functional team members while driving holistic product thinking across all squads. Fostering a user-centered culture that ensures cohesive experiences throughout the entire Mondly ecosystem.
//
design system
Co-leading the initiative to establish a comprehensive design system aligned with native platforms and web experiences. Collaborating closely with the Design Ops lead to implement a scalable, semantic token-based system that accelerates development and ensures consistency.
//
ai advocacy
Using AI prototypes for feature validation, vibe coding tools for internal workflows, generated more than 2000 images through Midjourney.

Interactions
& motion design
Interactions & motion design
My motion design experience shapes how I approach Mondly's interface. Rather than thinking in static screens, I visualize the learner's journey as connected storyboards. From onboarding through lessons to vocabulary review. Strategic animations, haptic feedback, and audio cues guide users naturally through their language learning progression.
//
challenges of tech debt
Mondly's legacy technical debt creates significant challenges—slow development cycles, platform inconsistencies, and accessibility limitations. These constraints have refined my strategic approach, forcing ruthless prioritization and creative problem-solving. The result: maximizing impact with minimal resources while building a foundation for future scalability.
