Summary
👤
Senior🎓
Top SchoolJulien Xavier is a senior back-end Java developer with nine years of professional experience and a strong full-stack background, currently focused on Kafka-driven compliance and fraud detection at BforBank. He builds and maintains event-driven microservices, implements KYC and regulatory rules, and optimized Kafka Connect pipelines to reliably sync topics with internal databases. Julien has led front-end projects at Galeries Lafayette, delivering award-winning internal apps and migrating large codebases to modern frameworks while also ensuring high test coverage and performance tuning. He combines hands-on backend engineering (Java, Spring, PostgreSQL) with frontend leadership (Vue/Angular/React) and cloud automation experience (GCP, AWS, Terraform). A Sorbonne Master’s candidate, he pairs academic grounding with practical work as an independent developer improving SEO and UX for small clients. Less obvious: Julien moves fluidly between strategic design (architecture, data validation/enrichment) and operational tasks like automated exports for fraud teams, making him effective across the delivery lifecycle.
