About Me
I'm a Data Engineer with a passion for building scalable data infrastructure and turning raw data into valuable insights. My expertise lies in Databricks, Azure, and the entire data ecosystem—from pipeline design to deployment.
With a background in Computer Science and a specialization in Data Science & AI, I combine academic rigor with practical experience. I've competed in Kaggle competitions and apply those same analytical skills to real-world business problems.
Currently, I work at a leading financial institution, focusing on data engineering, MLOps, and cloud infrastructure.
