Case study: O2X app

about

The O2X coaches' web portal allows trainers to create custom and template-based workout programs, share resources, and stay connected with athletes through seamless app integration. I was part of the design team, focused on UX research and consistent execution of design deliverables.

Translating complex training needs into an intuitive UX

Comparing O2X App with other projects in my career, this was where I truly participated in every single stage of product development. Although I wasn't the lead product designer, I refined my UX and product discovery skills, strengthened my iterative design approach, user testing capabilities, and overall design versatility - including direct client and user communication. This project became the foundation for my later leadership roles.

I worked alongside two incredibly talented designers who mentored me and guided the process, yet I had freedom to suggest strategic structural and visual solutions. During Discovery, I facilitated online workshops for the client and key users - like product matrix sessions - and later systematized the user desire map results.

Even though I worked alongside two incredibly smart and talented designers who mentored me and guided the process, I was given the freedom to suggest strategic structural and visual solutions.

This was one of my favorite parts of Discovery because the product was a portal for trainers working with military forces and similar audiences - firefighters, navy members, and so on.

The UX, tone of voice, and communication style were completely different from what I was used to. It was a real challenge for my communication skills - I had to quickly learn explaining design concepts in accessible language for everyone.

We had a great connection with the stakeholder on the client's side, which helped us gather a focused user group and define core pain points of the existing app. I carried out a full audit and analysis of the current product, focusing on structural, logical, and visual aspects. Through test usage, I identified numerous usability issues, created a detailed audit report, and later saw many hypotheses confirmed during real user testing.

One of my favorite methods - which I've used since my first year at university - is what I call emotional navigation in product design. 12 years ago, I chose my first research topic by observing what frustrated me, studying the problem, and proposing a solution. Surprisingly, this approach remains one of the most effective in personal research - right after data analysis.

MVP to real useful product:

→ analyze exicsting MVP and map the pros and cons
→ learn the best practice
→ conduct the deep product research

Find the best solution for the users´problems:

→ gather and complete the most fitting UX research methods
→ through itterative process, find the most optimal set of features for the product

This meant preparing design variations for stakeholder review and creating rapid prototypes to demonstrate functionality. I'd get nervous before every call, always feeling there was something to improve - but thanks to my mentors and positive client feedback,

I learned navigating dynamic client communication, overcoming imposter syndrome, and significantly strengthening my technical Figma skills - from variables and tokens to advanced component structuring.

Streamlined design process:
‍

→ gaining technical confidence within mentoring sessions
→ preparing agendas and staying within the timeline

Effective design-stakeholder communication:

→ demonstration of prototypes
→ elaborative presentations for the client to understand at what point we are

I prepared a big part of the prototypes, pre-tested designs, and used Maze for user testing. While I wasn't responsible for recruiting testers on this project, I had led user interview recruitment and tester hiring for others.

Together with my mentors, I analyzed testing results - and I was happy to see some of my favorite designs resonated better with users.

As part of our research, I conducted a live workshop-survey with real trainers to get direct feedback. I still remember joining that call and seeing twenty very serious-looking coaches on the screen - and there I was, asking them which shade of green they preferred! Saying I was nervous would be an understatement.

But thanks to my mentors and the client-side stakeholder, within ten minutes we were chatting easily like old friends. I showed design options and prototypes, asked for preferences, and discussed what raised questions. Seeing real-time feedback and brainstorming improvements with the team was incredibly rewarding.

Preparing a perfect testing environment:

→ request real app users for the testing
→ provide clear instructions and double-check the testing designs to make sure it works with no bugs

Maximizing benefits from the user testing:

→ gather the testing data and prepare detailed reports
→ propose various solutions based on the findings and integrate them in the final deliverables

Regarding design-dev collaboration, instead of preparing traditional reports with comments, I participated in real-time developers' workflow, helping make adjustments on the fly.

dev revisions

One of the most memorable moments was working on the promo video, where I directly contributed to process completion.

It wasn't my first collaboration with an animation specialist,

but I had to quickly prepare a large volume of material for the teaser's production.

Working under a tight deadline and anticipating audience reaction at the event gave me energy and motivation.

Dynamic design-dev collaboration:
‍
→ real-time work with dev
→ live adjustments to the design

Creating stunning media campaign:

→ effective communication with the media specialist
→ rapid delivery of the design files

It was also the project that helped me gain full confidence in leading stakeholder meetings, running user testing sessions, and later stepping into lead designer roles - making key product decisions without hesitation. 

This project laid the groundwork for my current leadership capabilities.
