About Aymeric

Web and Windows application designer, I mainly work with clients who wish to actively participate in the realization of their project. This close collaboration allows me to offer personalized support, both technical and pedagogical, often in a co-construction approach. I am also able to manage a project as a whole, from the scoping phase to the production phase.

I have a strong appetite for numbers and data, which I translate into clear, useful dashboards (KPIs) adapted to business objectives. Analyzing, visualizing, and formatting indicators are aspects that I particularly appreciate in my assignments.

I primarily work within the Microsoft ecosystem, with expertise in .NET, C#, SQL Server, Power BI, SSIS, Excel, Access, and VBA environments. I am also comfortable with other web technologies, particularly PHP and Angular.

My interventions often focus on projects already underway, facing technical blockages. I then provide concrete solutions, while ensuring the transfer of skills to teams or clients. Autonomous, I can move forward effectively on my own, but I find teamwork particularly enriching, both on a human and technical level. My frequently cited strengths: my ability to clearly explain technical concepts and the design of intuitive and ergonomic interfaces.
