UX/UI design

UX/UI and product design for teams building software

I design flows, interfaces and design systems for digital products people use every day. I work closely with product and engineering teams so that designs can be built, maintained and scaled.

Who it's for

  • SaaS companies whose interface grew without a system.
  • Teams with no dedicated designer, or with one who needs senior support.
  • Education and health platforms with complex flows, multiple user roles and sensitive data.
  • Products about to ship a major feature that want to validate it before building it.

What's included

  • Discovery: conversations with the team and a review of the current product and its critical flows.
  • User flows and information architecture.
  • Wireframes and interactive Figma prototypes.
  • Web and mobile UI design: final screens, states and responsive behavior.
  • Design system or component library: tokens, components and usage documentation.
  • Design validation with users or with the team, depending on the context.
  • Developer handoff: specs, components named as in code and support during implementation.

How I work

  1. Understand: business goals, users and technical constraints.
  2. Map: flows and priorities. What to solve first.
  3. Prototype: wireframes, then clickable prototypes.
  4. Validate: tests with users or with the team, depending on the context.
  5. Design and systematize: final UI and reusable components.
  6. Support development: implementation review and adjustments.

Where AI fits

I use it to speed up specific tasks: exploring layout variations, generating realistic placeholder content, building working prototypes faster and synthesizing research notes. Design decisions, judgment and user validation stay human work.

By project type

If you already know what kind of project you have, these pages go straight to the point.

  • E-commerce design

    Menu, categories and product pages designed so a large catalog can be browsed and compared.

  • SaaS and dashboard design

    Flows and management screens for products with complex rules, several user roles and sensitive data.

  • Design system

    Tokens, components and documentation in Figma so design and code share one foundation.

Frequently asked questions

Do you work with teams that already have designers?

Yes. I can join as senior support, build the design system or own a specific module.

Design only, or code too?

The main deliverables are Figma designs, prototypes and components. When the project needs it, I can also implement them: if you also need it implemented, see the web development service.

How do we start?

With a conversation to understand the product and the problem. Then I send you a proposal with scope and phases.

Have a product that needs structure, or a new feature to design?
