Hi, I'm Septian 👋

Business Analyst → Data Analytics → Finance Analytics

I'm an IT Business Analyst with 6+ years across enterprise projects — customer loyalty platforms, ERP integration, HRIS implementation, and digital banking. I'm now building great skills in data analytics, with the long-term goal of moving into Finance Data Analytics.


🎯 What I'm doing right now

  • Sharpening applied statistics, SQL window functions, and data storytelling
  • Building applied data analytics portfolios (BI dashboards, revenue analytics) as the foundation for Finance Data Analytics
  • Translating business-analyst instincts (root cause analysis, process rigour) into data-driven finance use cases

🛠️ Stack

Python · SQL · Google BigQuery · Looker Studio · Excel

📜 Certifications

📂 Featured Projects

  • hospitality-business-intelligence-analytics — End-to-end BI case study (Python, BigQuery, Looker Studio) for a boutique hotel: from raw data to business-ready dashboards.
  • FMCG-revenue-analytics — Revenue analytics case study modeled on FMCG business questions (e.g. Cimory-style revenue analyst use cases).
  • Campaign Performance Analysis Marketing campaign data analysis: a multi-dimensional PivotTable investigation uncovers a customer-type × campaign crossover effect that contradicts the initial "Campaign B wins" conclusion — with direct implications for budget allocation. Excel PivotTable Statistical Analysis
  • ETL-Python — Extract–Transform–Load pipeline built with Bonobo Python.
  • 🚧 FP&A Agent and Data Analytics Agent — planned, applying AI-agent concepts to finance and data analytics workflows

✍️ Beyond code

I write and share BI/analytics thinking through Play With Data, and I'm working on a book exploring critical thinking, root cause analysis, and Kaizen for Indonesian organizational contexts.
