Hi there, I'm Kerolos hani

Data Engineer | Passionate about Big Data

About Me

I am a Data Engineer with a strong focus on Big Data systems and scalable data pipelines, alongside a solid background in data analysis.

I specialize in building end-to-end data solutions including data ingestion, processing, and orchestration using tools such as Python, SQL, Apache Spark, Kafka, Airflow, and Databricks. I also work on transforming complex datasets into meaningful insights and dashboards using Power BI.

While I have experience in data analysis, my primary interest lies in designing and optimizing large-scale data engineering systems that enable reliable and efficient data-driven decision-making.
