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:
24.6%
Increase offer redemption
Customers redem offers within redesigned flow
20.4%
Increase points burning
Customers purchase with earned points
1%
Increase account registration
Customers who downloades the redesigned app create account
Alvalabs: building candidates assessment service
The challenge was to create an experience that is equally delightful for two very different audiences:
—Candidates — who often feel anxious and judged, and need a smooth, reassuring experience to perform at their best;
—Recruiters & Hiring Managers — who need clear, actionable insights fast, so they can shortlist and decide confidently;

From day one, I partnered closely with product managers, data scientists, and psychologists to shape Alva’s core product experiences. I designed core product experiences across candidate assessments, result visualization, and comparison tools to improve hiring decision workflows.
I had 3 main design focuses back then: candidate assessments (redesigning the UI to feel clear, supportive, and reduce test anxiety); recruiter dashboards & comparison tools (enabling hiring teams to make faster, more confident decisions) & design system (delivering a responsive, accessible system that unified the product and enabled scalability).
I collaborated daily with developers, sales, support, and stakeholders — driving design refinements, ensuring dev-ready handoffs, and keeping feedback loops tight via Slack and in-person sessions. This close collaboration helped us transform early ideas into a scalable, market-ready platform.
By the time I left, Alvalabs reduced candidate drop-off rate during tests (measured post-launch) & faster recruiter decisions thanks to simplified dashboards. Alvalabs had secured investments, expanded its client base, and integrated with major clients like TeamTailor. Today, Alva stands as a robust service offering a wide range of tools for candidate assessment and I’m proud to have been part of laying its foundation.
What I had learned through my Alva’s time that in hiring, UX isn’t just about usability — it’s about trust & reassurance and data visualization is crucial for recruiters to act quickly and confidently.
Building digital document web–service for pandadoc
PandaDoc was growing fast, serving thousands of teams who relied on it daily to send proposals, quotes, and contracts. Our challenge was to evolve the product experience to be faster, smarter, and more collaborative, while keeping it intuitive for new users.

As PandaDoc grew, the product needed to scale in multiple dimensions:
-
Expand beyond the web app and offer a mobile-first experience;
-
Support enterprise-level workflows like bulk sending, automation, and integrations;
-
Keep the Editor experience smooth and intuitive, even as new features were added;
- Deliver consistent, reliable UI across the platform as the team scaled rapidly.
As a Product Designer, I worked across nearly every corner of the product — from mobile to integrations to the core Editor experience. One of my first big initiatives was leading the design and launch of PandaDoc’s mobile app, bringing the platform to iOS and Android users and enabling document workflows on the go.
I also took on some of the product’s most complex challenges, such as designing Bulk Send, which allowed enterprise customers to send large volumes of documents quickly and reliably. Alongside this, I worked on refining the Editor experience — introducing features like reminders for fillable inputs, which significantly increased recipient engagement and completion rates.
Beyond the core product, I helped shape third-party integrations and designed template solutions tailored to customer needs, making it easier for teams to create, send, and manage documents at scale.
I actively participated in usability testing, conducted user interviews, and worked extensively with product metrics and tools like FullStory to evaluate live solutions and identify opportunities for improvement. I collaborated closely with developers, product managers, fellow designers, and company founders throughout the entire product development cycle — from ideation to implementation.
In September 2021, PandaDoc achieved unicorn status, becoming a $1B company — a milestone I was proud to contribute to through years of product evolution and growth.
At PandaDoc, I learned to think of a product as a living organism, not just a set of screens. I discovered that even well-intentioned design solutions must be measured, challenged, and sometimes revisited to truly achieve their goals and move the right metrics.

My name is Christina Matievskaya, a Product Designer with 10+ years of experience designing digital experiences that delight users and drive business impact. Born and raised in Minsk, now based in Stockholm.
Design is a complex process, and you can’t do it solo. I truly believe that achieving "good design" requires a transparent, supportive, and caring team. Of course, it must be clear and accessible for users and solve real-time problems taking into account business, tech and capability parts. In my work, I strive to create products that people trust, enjoy, and find meaningful.
I’m currently a Senior Digital Product Designer at Umain, part of Eidra, working on McDonald’s ordering application.
As part of a client-facing product team, I own design end to end: from user research, ideation, prototyping, to hands-on implementation and scaling our design system. I also mentor junior designers, shape design culture, and help define processes that make teams more effective. As design lead I focus on pushing research and usability testing, drive cross-team collaboration, create reusables asselts and run key design activities, including retrospectives and collaborative session.
As the Umain designer where I act as a Senior Product Designer with broader responsibilities. I help shape the design culture—through knowledge sharing, mentoring, and participating in recruitment. I help attact new business by taking part in preparing design proposals to sales pitch decks.
That’s a little about me. Let’s build something people love!
