What I'm looking for

I am looking for opportunities that allow me to innovate in data engineering and machine learning, within a collaborative and growth-oriented environment.

As a GCP Certified Data Engineer, I have honed my skills in designing and implementing large-scale data processing pipelines. My experience at Carrefour has allowed me to work extensively with Apache Spark and Google Cloud DataProc, optimizing data transformation and ingestion performance. I am passionate about leveraging technology to drive data-driven decision-making.

In addition to my technical expertise, I have developed real-time data processing pipelines using the Apache Kafka ecosystem, ensuring reliable data ingestion and transformation. My commitment to data security and compliance with regulations such as GDPR has been a cornerstone of my work, where I have implemented encryption and decryption protocols to protect sensitive information.

With a strong foundation in machine learning and deep reinforcement learning, I have designed frameworks that optimize big data pipelines, improving performance and resource utilization. My goal is to continue pushing the boundaries of data engineering and contribute to innovative projects that harness the power of data.
