A KYC platform that helps financial institutions verify customers and meet compliance rules.

  • Rebuilt core KYC products for their next version, with a faster, more compliant identity check.
  • Worked with engineers, UI designers and business analysts to match the frontend to new UX and business requirements.
  • Cleared frontend blockers through the rebuild, so the upgrade shipped on time.

A cloud platform that runs registrations, submissions and memberships for conference organizers.

  • Designed brand-consistent interfaces that improved the product experience across the platform.
  • Built reusable React components and a design system, for visual consistency and faster frontend work.
  • Bridged design and code for a 4-person engineering team, and cut the back-and-forth between them.

Coverse Studio

I design and build templates that help freelancers and job seekers win work: pitch decks, proposals and resumes.

  • Freelandeck, my client pitch deck template, is used by 55,000+ people on Figma Community.
  • I design and build each product myself: the Figma files and their variables (Freelandeck Premium switches between Light and Dark), the custom landing pages, and the code that generates CV Pro’s Word, Pages and PDF files.
  • CV Pro, my resume template: an open-source resume parser (OpenResume) read every field of its six one-page examples.
