Radja Kahoul

Hi, I'm Radja.

Senior Product Designer

4+ years designing for SaaS ecosystems, where different user archetypes need to find value in the same product.

At Malt for 3+ years, I worked on the core freelancer experience, from sign-up conversion and AI matching enhancements to transactional flows, shipping features that moved measurable metrics on a European-scale marketplace.

Freelance projects in seed and series A startups and a stint as founding designer taught me to efficiently pull the right skill from my toolkit at the right time.

With a background in product management at Polycea and studies at HEC Paris, I work at the intersection of user research, data tracking, strategy, and design.

My edge as a designer.

01

Start with the problem

I used exploratory user research to frame problems before jumping to solutions. At Malt, I worked closely with C-level to turn research insights into decision-making material.

02

AI in my workflows

I prototyped with AI tools early — Lovable, v0, Claude Code — to run user tests on rough concepts and iterate fast. I also built agents for recurring design work: UX writing, data event definitions, design system contributions.

03

Cross-functional by default

I facilitated workshops with data scientists, sales, customer care and C-level stakeholders to build an impactful end-to-end user experience.

04

Impact in production

I follow what I ship: tracking plans, session recordings, and interviews to dig into the why behind the numbers.

Case studies

Four projects, different constraints, all measured.

Teaching, writing, thinking out loud.

Product-passionate, I also like exchanging and getting enlightened by good discussions.

Let's work
together.
