Role and impact

Nikita owns problems end to end: frames what to build and why, makes product and design decisions, ships with engineers, and answers for the metric after release. He works as a partner on the problem, not a pair of hands for the solution — he wants to understand the goal, the metric and the constraints first, then proposes directions with trade-offs and helps pick one.

Languages

Russian, English.

Interview FAQ

How does Nikita work with engineers?

As early as possible and in their language. Brings engineers into discovery, shares Figma files with tokens and components, hands over specs as prototypes, and treats edge cases and empty states as part of the design, not follow-up tickets. Reviews implementation in the browser, not in screenshots.

How does Nikita work with product managers?

As a partner on the problem, not a pair of hands for the solution. Wants to understand the goal, metric and constraints first, proposes several directions with trade-offs, helps pick one, and is comfortable writing the first draft of a spec or cutting scope to ship.

What does his design process look like?

Start from the user problem and the business goal, look at data and talk to users where possible, move fast from rough flows to a high-fidelity prototype. Tests early with usability sessions, iterates in short loops and polishes motion, states, copy and accessibility.

How does Nikita handle feedback and disagreement?

Separates taste from evidence. Feedback about goals and users changes the design; feedback about preference is discussed openly and ideally settled with a quick test or data. Changes his mind when shown a better argument.

How does he measure whether a design works?

By the outcome it was meant to change: TTM, CTR, ROMI, CSAT, support load, task success. Looks for the number before and after, not only at the screens.

How does Nikita use AI in his workflow?

Uses AI-assisted coding tools as a daily part of the workflow for building and prototyping interfaces, exploring variants, and shipping side projects. Treats AI output as a draft that still needs design judgment, testing and polish.

How does he approach design systems?

As a shared language between design and engineering, not a component zoo. Tokens for color, type, spacing and radius live in Figma variables and are documented with states and usage rules. The system stays small and strict so teams build faster without inventing one-offs.

What kind of team and role is he looking for?

A senior or lead product design role in a product team that ships, ideally on a B2B SaaS, analytics or fintech product with real users. Works well directly with PMs, engineers and founders.
