At Pandai Education Sdn Bhd, I transformed raw data into more than 10 structured tables and built an automated data quality pipeline to validate row counts across 50+ tables.
I also built a Metabase funnel chart for the Pandai AI chatbot and maintained Looker Studio dashboards for internal teams and B2B clients. I delivered data requests covering SQL queries, reports, and dashboards.
As a Data Analyst Intern at Telkom University, I created a Microsoft Form to collect student records and an Excel dashboard that replaced manual tracking.
In personal projects, I built data pipelines with Airflow, dbt, and PostgreSQL or BigQuery. My earthquake pipeline matched USGS and NCEI events at a 94.3% match rate, and my Stack Overflow survey project included a salary prediction model served in Streamlit.
