Designed for humans.
Built with AI.

I use Claude Code, Cursor, and Figma to take ideas from concept to working product — faster than most teams, without sacrificing craft. 6+ years designing AI, fintech, consumer, and enterprise products. Open to senior IC and founding designer roles.

PROCESS

How I design and ship

Figma

My design source of truth. Every component, variant, token, and spec lives here — pixel-perfect, version-controlled, and always handoff-ready. It's not where I start exploring; it's where decisions become real.

Claude Code

Two superpowers in one tool. Through Figma MCP, I edit designs, inject mock data, and generate components without leaving my editor. Through the terminal — mine or Cursor's — I can build anything from scratch: prototypes, full features, entire sites.

Cursor

My primary IDE. I write, debug, and ship code here with Claude running inline as a pair programmer. It handles everything from quick component edits to full feature builds — including the site you're looking at right now.

Lovable & v0

When I need a directional concept in under an hour. I use Lovable and v0 to generate ugly-but-functional UI scaffolding fast — so teams can react to something real instead of a static mockup.

Paper.design

Connected to Claude Code via MCP, Paper becomes my live visual editor in the browser. I can build and see changes in real time — often skipping Figma entirely when I need to arrive at a solution fast, while still keeping full control to refine the details.

Perplexity & Claude

For research, competitive audits, and fast fact-checking. I also use Claude's Cowork to run persistent background tasks — daily competitor analyses, hypothetical user tests, content audits — so I arrive at work already informed, not just getting started.

  1. 01

    Understand the problem space

    Research, competitive audit, stakeholder alignment — before touching Figma.

  2. 02

    Rapid concept exploration

    AI-assisted sketching in Lovable or V0 to get ugly-but-directional fast. I'm not married to sketch #1.

  3. 03

    Design with structure

    Systems-first in Figma. Components, states, edge cases, data-heavy layouts. Real spacing, real type, real hierarchy.

  4. 04

    Prototype in the browser

    Claude Code + Cursor + Paper to build interactive prototypes that feel real — not clickable mockups.

  5. 05

    Iterate with data

    Usability sessions, PM feedback loops, and metric review. Ship, measure, repeat.
