Freelancer profile translated to English.

Description

Experienced SWE specializing in Java/TypeScript technologies. My professional aspirations are:

- To tackle new technical projects with significant business challenges.

- To enhance my skills in technical areas related to software craftsmanship and clean code guidelines.

- To improve existing codebases by introducing new practices or proposing new development standards to modernize your development team's application portfolio.

Throughout my career, I have contributed to numerous technically challenging projects, used by a wide range of end-users, where performance, high traffic, and code maintainability were key technical concerns.

I worked in the industrial sector before moving to the insurance sector. This curiosity to switch from one business domain to another demonstrates my ability to adapt to new functional contexts and to identify business value through my technical expertise.

For example, I contributed to projects involving B2B/B2C marketing data for Michelin products and am currently working on an application stack focused on managing policyholder documents for MAIF (insurance contracts, claims declarations, etc.) within the Document Management System (GED) ecosystem.

Interested in my profile? I am open to discussing any freelance software development opportunities!
