How I work

A process built around one outcome: conversion.

Step 01: Diagnose

Find what's costing you conversions before touching the design.

UX audit, funnel analysis, user research, I map exactly where visitors drop and why. Every decision that follows is grounded in data, not assumptions.

→ UX & Conversion Audit
→ User Research
→ Funnel Mapping
→ Success Metrics Definition

Step 02: Architect

Structure that guides visitors toward action.

Sitemap, information architecture, and CRO copywriting: the invisible layer that determines whether a page/screen converts before a single visual is designed. The right structure makes the design job easier and the results better.

→ Sitemap & Information Architecture
→ Wireframes
→ CRO Copywriting
→ Content Hierarchy

Step 03: Design

Every pixel earns its place.

Visual direction, responsive design, trust signals, and micro-interactions all aligned with one goal: removing friction between the visitor and the action you want them to take.

→ Visual Direction & Moodboard
→ High-Fidelity UI (Figma)
→ Design System
→ Responsive Design
→ Interactive Prototype

Step 04: Ship & Measure

Delivered clean. Tracked carefully.

Handoff documentation that developers actually use, followed by A/B testing and performance analysis to validate what works and push further. Through L'Escadrille, Webflow dev and growth strategy are covered end-to-end.

→ A/B Testing Strategy
→ Performance Tracking
→ Dev (via L'Escadrille Collective)
