What I'm looking for

I seek roles focused on data engineering or application development where I can solve integration challenges, build reliable ETL pipelines, and grow within collaborative, product-minded teams.

I am a Mathematics graduate from the University of Indonesia with over three years of progressive IT experience at Bank BNI, working across trainee, web developer, application developer, and data engineer roles. I combine strong analytical foundations with hands-on technical skills in ETL, database design, and financial application development.

At BNI I supported ERP migration (Oracle GL), built IBM DataStage job sequences and parallel jobs, authored PL/SQL packages for reporting, and developed C# console and enterprise applications for compliance and reconciliation. I have a track record of improving ETL performance, ensuring data integrity, and automating reporting workflows.

I am motivated by solving complex data integration challenges and delivering reliable, efficient solutions that support business and regulatory requirements. I bring adaptability, an agile mindset, and practical experience in both legacy COBOL systems and modern data engineering toolchains.
