EJ Colina

Senior Product Designer with 9 years in design and 4+ leading end-to-end product design for B2B SaaS and AI products built on dense data: tables, filters, permissions, and reporting. I work directly with founders and engineering teams to define product structure, ship design systems, and turn technical complexity into experiences anyone can use.

Core strengths

  • Figma (advanced): components, tokens, variants, prototyping
  • High-fidelity interactive prototyping & motion comps
  • Workshop facilitation (FigJam / Miro)
  • AI-assisted prototyping (Claude Code); ships to branch for engineer review
  • Design systems: architecture, cross-project libraries
  • Figma to code via MCP: components verified in Storybook, prototyped on Shadcn
  • Onboarding, activation UX, monetization & retention flows
  • Design tokens with multi-brand modes across products
