Freelancer profile translated to English.

Description

Looking for a backend and fullstack web developer to strengthen your teams, guide them towards good development practices, and optimize your build processes?

Independent developer with +6 years of experience, I specialize in Java (Spring Boot, Hibernate) with proven expertise in Kotlin (Quarkus), Node (Nest), and React. I apply SOLID principles and encourage the adoption of automated tests.

I have contributed to strategic projects for major French groups:

Orange: Data consistency management with a 40% reduction in anomalies
SNCF Connect: Redesign of the purchasing workflow, increasing conversion rates by 15%
Canal+: Migration of the legacy middleware with 0 service interruptions
Vallourec: Performance optimization reducing processing times by 60%

Recently, I participated in the launch of an MVP for a health tech startup, delivering a complete application in 4 months that secured Series A funding.

I work primarily remotely, with occasional travel for workshops and strategic meetings.

Daily rate between €500 and €600 depending on project complexity.

Looking forward to discussing your specific needs.
