HOW I WORK

The Process Behind the Work

STEP 01

Understand the problem

Before anything opens in Figma, I need to know what's actually broken. I talk to stakeholders, dig into user behavior, and use AI to help synthesize research patterns quickly so I can spend more time on interpretation than aggregation

STEP 02

Define what to solve

Most design problems are symptoms. I go further to find the root, then frame a clear problem statement that keeps the work focused and the team aligned

STEP 03

Map the experience

I map out how users currently move through the product and where things fall apart. This is where patterns show up that wireframes alone would miss

STEP 04

Explore and decide

I explore multiple directions early, get feedback fast, and cut what isn't working. AI tools like Claude, Lovable and Cursor let me build working prototypes instead of static mockups when the problem needs it. I'd rather kill a bad idea in a sketch than after two weeks of high-fidelity design

STEP 05

Test and refine

Real users, real feedback. I test assumptions before calling anything done and use what I learn to sharpen the details that matter most

STEP 06

Ship and follow through

I hand off with full context, work closely with developers during build, and use AI to help document design decisions, generate component notes, and keep specs thorough. The work doesn't end when the file is delivered
