Senior Product Designer · Fintech · Design Systems

I design financial products and the systems behind them.

Mobile journeys, multi-brand platforms, and design-to-code delivery for regulated environments.

A public-safe reconstruction combining a regulated onboarding state with the token contract behind a multi-brand product.

Selected work

Systems, states, and delivery under real constraints.

  • Design systems
  • Multi-brand platform
  • Design-to-code

Rebuilding the contract between design and code

A drifting multi-brand platform turned into a shared design-code contract with clear tokens, component ownership, and a source of truth engineering could use.

How I work

Product design capabilities

Complex flows

End-to-end journeys, recovery paths, edge states, and regulated constraints.

Systems

Tokens, themes, component contracts, reusable patterns, and source-of-truth work.

Delivery

Prototypes, specifications, design QA, and direct alignment with implementation.

About

Product judgment that survives implementation.

I work best where product complexity, regulation, and implementation constraints meet. I stay close to engineers because a design that falls apart in code is not finished.

I use AI for mechanical analysis, audits, and automation. I do not outsource product judgment. The decisions, trade-offs, and quality bar remain mine.
