About Koly

With solid experience in digital product management, I have developed a real passion for innovation and process optimization, with the constant goal of creating high-impact solutions that meet user needs while generating value for the company.

As a Product Owner and Product Manager, I was responsible for defining the product vision, prioritizing needs, and managing the entire lifecycle—from ideation to market launch. For example, I led the redesign of a data dashboard to optimize decision-making, managed the development of an internal management web application, and coordinated the implementation of a decision-making Datamart to improve the quality and reliability of key performance indicators (KPIs).

In my roles, I translated business needs into user stories, defined clear priorities, and worked closely with technical, UX/UI, data, and marketing teams to design and deliver high-performing, user-centric products.

I developed and managed structured product roadmaps, defined MVPs to quickly test hypotheses, and managed iterations using Agile methodologies (Scrum, Kanban) to ensure smooth execution and continuous product improvement.

🧭 Key Skills:

Development of product roadmaps and MVP definition

Analysis and prioritization of user and business needs

Product backlog management and agile ceremonies facilitation

Coordination of multidisciplinary teams (Tech, UX, Marketing, Data)

Data-driven management (KPIs, dashboards, user feedback)

Launch and growth of digital products

Communication and stakeholder management

Always seeking new challenges, I am committed to designing useful, scalable, and meaningful digital products that contribute to the company's strategic vision and influence.

    As a Data Product Owner / Product Manager, I served as the link between business teams, technical teams, and various stakeholders to ensure the creation of high-value data products.

    I defined the product vision, identifying user needs and aligning the data roadmap with the company's strategic objectives.
    I managed the product backlog, prioritizing key features—whether analytical dashboards, data pipelines, APIs, or predictive models—based on their business value and technical feasibility.

    On a daily basis, I coordinated multidisciplinary teams (data engineers, data scientists, developers, analysts) to ensure the successful execution of projects and maintain smooth collaboration among all actors.

    I monitored the delivery of data products, ensuring the quality of deliverables, adherence to deadlines, and consistency of deployed solutions.
    I also managed product performance by defining and tracking key performance indicators (KPIs) while ensuring regular communication with internal and external stakeholders.

    Finally, I implemented a continuous improvement process by gathering user feedback and adjusting priorities to optimize both user experience and the business impact of the delivered data products.

    As a Project Manager, I was responsible for the planning, coordination, and supervision of all stages of the migration to a new solution, ensuring quality, performance, and end-user satisfaction.

    I managed the migration from start to finish: from defining the schedule to managing the design, testing, and deployment phases, while ensuring adherence to deadlines and business requirements.

    I coordinated technical teams, business teams, and external partners (vendors, suppliers) to ensure smooth communication and perfect synchronization among all project stakeholders.

    In a proactive approach, I identified and managed migration-related risks (data loss, service interruptions, system compatibility) and defined contingency plans to secure operational continuity.

    I supervised the quality and integrity of the migrated data, ensuring its security, compliance, and consistency with internal and regulatory standards.

    To support the project's success, I managed change management, trained users, prepared documentation, and facilitated the adoption of the new solution within the teams.

    Finally, I managed post-migration monitoring, tracking performance, gathering user feedback, and managing necessary adjustments to optimize the stability and efficiency of the new system.

    April 2020 - December 2022 (2 years and 8 months)
    Paris, France
    As part of a digital transformation project, I managed the migration from the old CRM to Salesforce to improve sales performance, data quality, and collaboration between business teams.

    I led scoping workshops with the sales, marketing, and customer service departments to identify functional and technical needs, then defined the project roadmap, milestones, and the scope of Salesforce modules to be deployed (Sales Cloud, Service Cloud, Marketing Cloud).

    On the technical side, I supervised all data migration operations (ETL), ensuring their integrity, compliance, and security. I managed Salesforce integrations with existing systems (ERP, messaging, marketing automation tools) and coordinated technical teams, business teams, and Salesforce partners to ensure smooth project execution.

    I implemented a risk management plan, anticipating potential migration incidents or service interruptions, and oversaw the unit testing, integration, and user acceptance testing (UAT) phases before go-live.

    To ensure successful deployment, I supported change management: user training, production of functional and technical documentation, and post-deployment support.

    Finally, I managed post-migration monitoring, tracking CRM performance, analyzing user feedback, and managing necessary adjustments to stabilize and optimize the solution.

    This mission resulted in a successful migration without business interruption or data loss, rapid adoption of the new tool by the teams, and a measurable improvement in sales productivity and customer data reliability.
