What I'm looking for

I am looking for opportunities that allow me to leverage my data engineering skills in a collaborative environment focused on innovation and growth.

I am a data engineer with hands-on experience in designing and maintaining end-to-end data pipelines. My focus is on improving data reliability and automating repetitive workflows. At Western Digital, I designed and implemented a data health alert and monitoring system that significantly reduced data loss from approximately 50% to near zero. This achievement underscores my commitment to ensuring that data arrives clean, accurate, and on time.

In my role, I built a scalable end-to-end ETL pipeline using Apache Airflow, which enabled the analytics team to access timely and reliable data. I also maintained and optimized an existing ETL pipeline that was critical for delivering daily insights to business teams. My experience extends to tutoring students in math and computer science, where I helped them grasp complex concepts and improve their problem-solving skills.
