About

Hi! I'm Atha, a Data Analyst at Astra Graphia Information Technology with a passion for turning complex data into decisions that actually matter. My work spans Power BI & MicroStrategy dashboards, SQL Server, SSAS optimization, and — most recently — agentic AI pipelines. I won 1st place at iFuntastic 2025 (Astra Graphia's internal innovation competition) for building an end-to-end AI automation pipeline that reduced Jira ticket resolution time by ~90%. Day-to-day, I build dashboards that support executive decision-making, optimize query performance (cut load time by ~60% via SSAS migration), and develop ML models that improved campaign targeting accuracy by 90%. I came from an unlikely background — Psychology — but that's exactly what makes my approach different. Understanding
