Freelancer profile translated to English.

Description

Throughout my professional experiences, I have developed solid expertise in Full-Stack development, notably by combining:

Backend Java/JEE and Spring Boot, with the design of robust, secure, and scalable REST APIs.

Frontend Angular, for building modern, responsive, and user-centric interfaces.

Passionate about new technologies, I oriented myself towards cloud computing and successfully obtained the AWS Architect certification, attesting to my ability to design and orchestrate reliable, scalable, and performance-oriented architectures on AWS.

During my recent assignments, I integrated Apache Kafka to implement asynchronous data streams, enabling real-time and streaming data processing.

I have also acquired solid expertise in the Big Data ecosystem, particularly with Apache Spark and Hadoop, for distributed, massive, and high-performance data processing. These skills have allowed me to optimize large-scale analytical applications, reduce computation times, and ensure the scalability of Big Data pipelines.

In summary, I am a Cloud-oriented Full-Stack Java & Big Data engineer, capable of designing innovative, high-performance solutions aligned with business needs.
