Senior Product Designer & Design Engineer
SeLoger Bureaux & Commerces.
When I joined SeLoger Bureaux & Commerces, the product was mainly perceived as a simple listings website. My mission was to rethink the experience and help transform the platform into a professional Commercial Real Estate product, creating a sustainable competitive advantage through product strategy, user research, and UX/UI design.
Understanding a
complex market
The Commercial Real Estate (CRE) market is highly fragmented, with different professional needs depending on the type of property.
Through stakeholder workshops and market analysis, I helped structure the product vision around three key pillars: Retail / Offices / Industrial & Logistics / Plot
This segmentation aligned the platform with how professionals actually search for commercial properties and helped clarify the product positioning.
Trust & High Performance
Commercial real estate transactions involve significant financial commitments. The interface therefore needed to communicate trust, clarity, and expertise.
I redesigned key parts of the platform to improve: • information hierarchy • data visibility • professional credibility
These improvements helped reposition the product from a simple listings website to a professional CRE decision tool.
Fast Delivery,
Continuous Discovery
To accelerate product progress, I introduced a dual-track approachcombining delivery and discovery.
Fast Lane Continuous UX improvements and quick wins to improve the existing experience and deliver value quickly.
Experimental Lane More exploratory initiatives focused on validating new product opportunities through user interviews, data analysis, and high-fidelity prototyping.
Both tracks were driven by a shared backlog of opportunities, mixing quick improvements and deeper product explorations. This approach allowed the team to ship improvements quickly while continuously learning from users and validating product ideas.
Measurable &
Historic Impact
The transformation of the platform generated strong and measurable business results.
- 38% Market Share
- +40% YoY Growth
- 2.5x CVR Increase
- +125% SEO Traffic
The Full Scope
This project mobilized the full scope of my design practice:
product strategy, user research, UX/UI craft, and experimentation.
By combining strategic positioning, continuous discovery, and fast delivery, we transformed the platform into a market-leading product.
Looking back, this project also shaped the way I approach design today: combining strategy, prototyping, and experimentation to drive measurable product impact.
