Hi, I'm Radja.

Senior Product Designer

4+ years as a product designer with a PM & business background, specialized in complex SaaS and data-heavy products. I frame problems with data, design the answer, and can ship it to production with some dev PR support.

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.

I use exploratory user research and data (SQL) to frame problems before jumping to solutions. At Malt, I worked closely with C-level to turn research insights into decision-making material.

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.

Studies at HEC Paris and a product management experience at Polycea gave me the business and analytical foundation that shaped how I work.

My edge as a designer.

01

Problem-first

With a PM background, I work upstream — structuring problems with data and user research before a single frame is drawn. At Malt, that meant turning research insights into C-level decision-making material.

02

Research and data first

I use exploratory user research and SQL to frame the right problem before designing the answer. I also build agents for recurring research work using Dust, n8n, and Claude.

03

Close to production

I write code, push PRs, and use Claude Code to audit codebases and prototype directly. It makes collaboration with engineers smoother and decisions faster.

04

Cross-functional by default

I facilitate workshops with ML engineers, sales, customer care and C-level to turn research insights into shared product decisions.

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.
