Hi, I'm Maulana Hasyim — a Data & Business Analyst. I build dashboards, model business processes, and deliver actionable insights for enterprise organizations such as Pertamina and BRI.
Bachelor of Informatics Engineering from UIN Syarif Hidayatullah Jakarta (GPA 3.61/4.00), specializing in Data Analysis, Data Visualization, and IT Business Analysis.
I'm experienced in building dashboards, conducting business process modeling, and delivering strategic insights. My focus is on transforming complex datasets into solutions that support decision-making and business growth — using Power BI, Tableau, SQL, Python, and BPMN tools.
Contributed to business process leveling for agreement workflows, mapping processes in detail with Excel & Visio, and verifying BPMN flowcharts in ARIS Tools — validating notations, risks, and control elements against the company's SOPs.
Designed interactive dashboards with Tableau, and created 250+ business process flowcharts (micro credit, bank guarantee, digital lending) using ARIS BPMN — complete with risk, control, and input-output document elements, plus Value Added Chain Diagrams for process leveling.
Supported the Technology & Development team on the Shared Services Project: designed and built Power BI dashboards sourced from Excel and SQL Server for Asset Management, and prepared Scope of Project and User Acceptance Testing documents.
Developed features for the bnpp.go.id website using PHP, HTML, CSS, JavaScript, and MySQL, and conducted usability testing that helped the team redesign the site.
A dashboard to analyze service requests, incident management, and RDP inventory across all Pertamina regions — processing 10,000+ requests and 78,000+ inventory items.
A comparison of Multinomial Naive Bayes vs Decision Tree with hyperparameter tuning for text classification, reaching up to 90% accuracy (AUC 0.95).
Visualizing access levels of the BRIPEDIA learning platform across regional offices nationwide, with monthly rankings and up/down trend analysis.
Customer segmentation using K-Means clustering, determining the optimal number of clusters via silhouette score, followed by a classification model to predict segments.
An interactive tool to filter 37,800+ internship vacancies by province, role, and major — complete with analysis of the most in-demand majors & education levels.
Modeling banking business processes (micro credit, bank guarantee, digital lending) using ARIS BPMN and Microsoft Visio, aligned with Bank BRI's SOPs.
Interested in collaborating, have a job opportunity, or just want to talk about data? I'd love to hear from you.
