About Jean-Jacques

Freelance Full Stack & Windows Applications Developer

Looking for a developer who can quickly take over an existing project, modernize a business application, or develop a custom solution?

I support companies in the design, development, maintenance, and evolution of their web and Windows applications.

I specialize in Full Stack development (PHP, .NET, C#, ASP.NET, Vue.js, SQL, MySQL, HTML, JavaScript, jQuery) as well as Windows applications developed in Delphi, C#, or Visual FoxPro, particularly for their maintenance, evolution, or migration to newer technologies.

Throughout my projects, I have developed solutions in various fields such as accounting, sales management, resource management, internal company management, medical software (practice management and prescription generation), and tax declaration applications.

I particularly enjoy projects that require a quick understanding of existing systems, solving complex technical problems, and proposing reliable, performant, and sustainable solutions.

Available for short or long-term assignments, I can also provide ad-hoc support for targeted expertise, team augmentation, critical bug fixes, or specific enhancements.

My goal is simple: to provide you with an effective solution, quality code, and rapid integration into your projects.
