Approach

I build products designed for retention.

Behavior


  • Design for return, not just arrival.

    I focus on the moments that make a product useful enough, clear enough, and rewarding enough to come back to.

  • Start with what the user is trying to do.

    To build momentum and create habit, I look at what the user wants, what might stop them, and what would make the next action feel obvious.

  • Create momentum.

    People come back when they feel progress. I help users understand where they are, what changed, and why the next step is worth taking.

Product Direction


  • Turn ambiguity into product vision.

    I take loosely defined opportunities, find signal quickly, and shape them into clear product direction teams can align around and ship.

  • Think at product altitude.

    I partner with founders, executives, PMs, and engineers to define what should exist, why it matters, and how to bring it to market.

  • Lead from inside the work.

    I’m a player-coach. I lead teams to do their best work, while staying deep in the highest-impact parts of the product.

Craft & Scale


  • Build systems, not one-offs.

    I design reusable patterns for discovery, participation, decision-making, and trust, so products stay coherent as they grow across features and platforms.

  • Prototype to learn fast.

    Working artifacts surface interaction issues early and align teams faster than decks.

  • Craft earns trust.

    When attention is scarce and choices matter, clarity, motion, and restraint signal competence. The first interaction determines whether users stay.

Valentin, Product Designer

About Me

I turn ambiguous product bets into experiences that become habits.

I'm a product design leader with 15 years of experience across consumer finance, crypto, social, and wellness. My edge is connecting user behavior, craft, psychology, and business reality to create products that build trust, create momentum, and drive measurable growth.

Contact

Let's talk.

I’m always interested in serious product conversations, especially when the problem is hard, the stakes are real, and design can change the outcome.
