What I'm looking for

I seek roles where I can build robust data pipelines, ensure data quality, and support analytics/ML teams in a collaborative, growth-oriented environment.

I am a third-year Information Systems student at Gunadarma University with practical experience in end-to-end data workflows, data cleaning, validation, and transformation using SQL and Python. I have processed large public and transaction datasets, optimized queries in BigQuery, and supported downstream analysis and dashboards across healthcare, retail, and finance projects.

I bring hands-on experience with Snowflake, PostgreSQL, PySpark, Airflow, and GCP, and I actively participate in developer community events to stay current with cloud and data infrastructure trends. My work emphasizes data quality, pipeline robustness, and making complex datasets accessible for analysis and machine learning.
