I build Products people understand at a glance.

Product designer. Four cases, each starting with the problem and saying plainly where the evidence stops.

2026 · Banking · Independent redesign

On Home, immediate needs and discovery content competed for the same attention.

What I did: Ranked Home by urgency: money and actions first, services and promotions after. Compared two layouts, A and B, against the current one.
How sure we are: Independent redesign from public evidence only. No internal data; validation is planned, not done.

2025 · B2B SaaS · Web and mobile

Every department had its own tool, so work stalled at every handoff.

What I did: Traced the root cause to a missing shared product model, then designed shared rules for requests, approvals and status across web and mobile, plus a design system from zero.
How sure we are: Customer details and some internal metrics are under NDA. This shows decisions and methods, not results.

2022 · Retail · Website

Shoppers could start buying with questions about the product, the offer or the delivery still unanswered.

What I did: Owned UX direction for Home, Category and Checkout. The rule: cut visual noise, not decision information, and show each fact when its decision becomes active.
How sure we are: Shows what was designed and why. No impact numbers are claimed; none can be defended without the source analytics.

2026 · Travel · Independent exploration

Booking a seat took six steps, and the discount rules only showed up at payment.

What I did: Drafted two prototypes to test: A shows price and discount conditions early; B merges six steps into four.
How sure we are: Discovery stage: built from screenshots and one screen recording, with no analytics or passenger research. Both prototypes are hypotheses.

Start with the problem.
A solution only makes sense next to the problem it answers, so every case opens there.
Say where the evidence stops.
Independent work is labelled. Targets are not results. No number appears without its source.
Show the real screen.
Real product screens lead. Diagrams are drawn, not pasted.
