Scholastica Alphonsus

I’m a seasoned Senior Data Engineer with more than 15 years of hands on experience in data engineering, business intelligence, data quality, and performance analytics. My professional journey spans leading oil & gas and energy companies in Malaysia, including Petronas and Bumi Armada, where I’ve delivered impactful, enterprise level data solutions that empower decision making, ensure operational excellence, and unlock the true value of data.

Over the years, I’ve built a solid reputation for designing clean, insightful, and business aligned dashboards, implementing automated data quality checks, and architecting robust data pipelines to drive reliable reporting and analytics. My primary tools include Power BI, SQL, Talend, and a range of Azure cloud components.

What sets me apart is my combined experience as both a Data Engineer and a Performance Analyst. I not only know how to code and build data models, but also understand what business leaders and operational teams truly need.
