Bukan cuma portofolio, tapi catatan perjalanan belajar data sambil kerja.

Di halaman ini aku lebih fokus berbagi tulisan tentang data, beasiswa, dan tools seperti Power BI, Tableau, dan Python yang kupakai sehari-hari — bukan sekadar memajang CV.

About Me

A data practitioner with a solid foundation in mathematics, analytics, and modern data tools.

I’m a passionate data practitioner with a strong background in mathematics and experience across data analytics, data science, and AI training. I enjoy working end-to-end with data: collecting, cleaning, analyzing, visualizing, and communicating data-driven insights for both technical and non-technical stakeholders.

I’m comfortable working with Python, R, SQL, and Elasticsearch, and I use tools like Microsoft Office, Google Workspace, Tableau, Power BI, and Kibana to transform data into clear and actionable stories.

I graduated with a Bachelor’s degree in Mathematics from Brawijaya University, and I’ve been trusted as an LPDP Scholarship Awardee (2024), Bank Indonesia Scholarship recipient (2019), and KSE Scholarship Awardee (2020). I also have a publication on actuarial modeling for COVID-19 insurance.
