    Livtoo • A dating app based on compatibility

    WHAT IS LIVTOO?
    Unlike traditional mobile dating apps, Livtoo focuses on compatibility rather than appearance. The goal is to allow users to connect based on their shared values, interests, and aspirations, for deeper and more lasting relationships.

    MY ROLE IN THE PROJECT
    I was responsible for the end-to-end design of the application, working on several key aspects:

    -> Understanding the concept• in-depth discussions with the creators to grasp their vision and the project's stakes.

    -> UX/UI Design •creation of complete mockups with a user-centered approach, ensuring fluid and intuitive navigation.

    -> Creation of the visual identity• definition of colors, typography, and graphic elements to give Livtoo a strong and coherent identity.

    -> Development support• now that the mockups are finalized, I am assisting the developer to ensure faithful integration of the design.

    -> Visual communication• creation of content for social media to support the launch and engagement around the application.

    ADDED VALUE

    **-> A design focused on maximizing user engagement**, in line with the expectations of the dating app market.



    **-> Support on product strategy**, to refine and make the concept even more concrete and attractive.



    **-> Development monitoring**, ensuring consistency between the design and the final product.

    Addworking • Rethinking subcontractor management with SaaS software

    WHAT IS ADDWORKING?
    Addworking is a SaaS solution that facilitates the management of relationships between clients and subcontractors. The tool allows companies, particularly in the construction sector, to centralize and streamline their exchanges with their service providers, in an environment where digitalization is still a challenge.

    MY ROLE IN THE PROJECT
    I was responsible for the complete redesign of the software and the creation of new products adapted to client needs. To do this, I worked on several key aspects:

    -> UX/UI Design of the new SaaS version• development of mockups adapted to a target audience unfamiliar with digital tools.

    -> Creation of new products• strategic thinking and implementation of features specific to user needs, particularly in the construction sector.

    -> Simplification and accessibility• clean and intuitive design to ensure easy adoption, despite a complex business environment.

    -> Close collaboration with developers• monitoring and adjustments to ensure smooth integration of the design into the final product.

    CHALLENGES AND SOLUTIONS PROVIDED
    -> A target audience distant from digital tools• I designed clear and accessible interfaces, avoiding unnecessary complexities.

    -> A demanding and regulated sector (construction, subcontracting, compliance, etc.)• I ensured the integration of features facilitating administrative and contractual management.

    -> A smooth transition to a new version• work on ergonomics designed to minimize user resistance to change.

I called upon Louis for a UX audit of my app's paywall, which was suffering from a very low conversion rate. Result: an in-depth analysis, clear and prioritized recommendations that I am already implementing. What convinced me: he didn't list generic problems but truly understood my product's context and business stakes. The exchanges were very smooth and professional. If you are looking for a UX expert who understands users as well as conversion, I recommend Louis! I would use his services again without hesitation.
