Three products in one year
Context
MegaFon is one of Russia's largest digital providers — 77M+ subscribers and a major consumer app sitting on top. A high-load B2C product in an enterprise environment: several cross-functional teams shipping in parallel, and a new design system being rolled out across all of them at the same time.
I joined as a Senior Product Designer. Over the year I ran three big projects in parallel — a main-screen redesign with design-system rollout, a new voice assistant against spam, and the company's first family-plan product.
What we did
Main screen: redesign on a new design system
The app's main screen had aged past the point of incremental patches — its components no longer matched the new design system. Four-plus product teams each owned a different block of the same screen. Without a single coordinator, review and layout would have drifted in four directions.
I ran the flow as much as the design. Set up cross-team design reviews on build candidates in a constant-improvement cadence, so integration issues surfaced weekly instead of at launch. Kept communication explicit between the teams owning different blocks. Designed a splash-screen animation to improve perceived loading speed while the new screen warmed up. Coordinated the launch between design, engineering, and QA.
Result
Successful rollout of the new main screen with components from the new design system. Payment transactions ×1.5, MAU ×1.5, DAU ×2, revenue +30%.
Mega Family: MegaFon's first family plan
A new product line with no precedent in MegaFon's catalog: shared usage of minutes, SMS, and data between people or devices inside a single family plan. No existing flows to borrow from — had to build the concept, the user flows, and the screens from scratch.
Ran usability tests on the first complete version and shipped the fixes into the launch build.
Result
Launched as a new product line, with meaningful growth in daily new-subscriber connections.
Agent Eva: a voice assistant against spam calls
Spam calls are a mass pain point for subscribers. Competing services already existed on the market; the goal wasn't to match them but to beat them on ease of use and reach.
I designed the product from zero — the activation flow, the settings, the state screens for both the voice and the text assistant. Several rounds of UX testing with real users, with iteration after each round.
Result
500K users in the first three months after launch. 8M+ users after a year. #2 in Russia by user count among comparable services.
Result
Three parallel projects delivered in a year, each in a different shape: a redesign with a design-system rollout, a new product built from zero that reached millions of users, and a first-of-its-kind product line for the company.
A few things stuck with me after this year. At 77M subscribers, even a small UX defect becomes millions of bad touches a day — that rewires how you prioritise. When four or more teams share one screen, a designer who runs the flow is worth more than one more designer on the canvas. And for anything built from zero, there is no substitute for research: without testing, it is impossible to predict where a user will trip.
