🚀 Robust architectures serving your data.
Backend Developer with a hybrid profile, I combine technical expertise and Business Intelligence. I don't just code: I build robust architectures and resilient APIs that transform your data into real decision-making levers.
I work across the entire value chain of your applications and data:
- - Backend & API Architecture: Design and development of secure and scalable REST APIs (Java Spring Boot, Symfony, Laravel).
- - Data Engineering: Creation and optimization of ETL/ELT flows (Talend, Advanced SQL) to ensure data reliability.
- - Business Intelligence: Implementation of interactive dashboards (Power BI, SAP BI) for strategic management.
- - Optimization: Audit of SQL queries and automation of business processes.
My dual expertise allows me to understand the business challenges behind the code. I design my databases (Snowflake, Oracle) and my flows with performance and maintainability in mind from the outset, avoiding future technical debt.
Examples of achievements:
- -Groupe Avril:Development of connected solutions combining BI and Backend to ensure the reliability of critical reporting.
- -Architecture:Design of complex Restful APIs and containerization of environments (Docker).
- -Data Viz:Creation of management dashboards connected to production databases.
I adapt to the demanding environments of large groups (Industry, Services) as well as agile structures.
🛠 Technical Stack:
- -Backend:Java (Spring Boot), PHP (Symfony, Laravel), Python, C#.
- -Data & DB:SQL (Oracle, MySQL, Postgres), NoSQL (MongoDB, Neo4j), Snowflake.
- -BI & ETL:Power BI, SAP BI, Talend, SSIS.
- -DevOps & Cloud:Docker, Azure, GCP, Git.
