About
The person behind the keyboard.
I'm a User Experience Designer at Fidelity, focused on institutional crypto. Since 2016 I've been working in the financial tech industry, always putting the user first while collaborating across multiple teams.
Outside work you'll usually find me at a friends playing a tabletop roleplaying game or tinkering with my gaming PC.
Skills
What I bring to the table.
Figma
Shared libraries and prototypes set up so designers and engineers hand off cleanly.
Accessibility
WCAG 2.2 work that goes past automated audits to meet each user's needs.
UX Personas
Personas grounded in research, always keeping the user's needs and goals at the center.
Usability and User Testing
Moderated and unmoderated studies that settle debates and point to the fixes worth making.
Information Architecture
Structure for complex financial flows, so users always know where they are and how to get where they need to go.
Rapid Prototyping
Working prototypes that test an idea with real interaction before anyone writes production code.
UX of AI Features

I own the design for Fidelity's institutional custody crypto products and its design system. I've shipped new products and features built around trust and clarity, so clients can seamlessly manage their funds while building confidence in their interacitons.

- Led early UX accessibility work, rebuilding core components to WCAG 2.2 AA alongside the engineers who shipped them.
- Ran usability studies that settled crucial design debates, then saw the fixes through to the live site.

Type
H1
Page title
The one big headline at the top of a page. Only one per page.
H2
Section heading
Starts each major section, like About or Experience.
H3
Subheading
Titles inside a section, like a company or a card.
Body
The text you read in paragraphs and lists.
Everything that is not a heading.
Headings are set in Fraunces; body is Montserrat, the original brand typeface from the site and resume. Sizes step down on a fixed scale so the hierarchy stays consistent on every screen.
Components
Each of these is defined once and reused across the page.
