Hi, I'm Guntur. I dig through the spreadsheets, SQL tables, and messy exports until a clear story shows up — then I tell you exactly what to do about it.
It started with a spreadsheet Guntur couldn't stop tinkering with — and it never really stopped. These days, he spends his time turning "we have a lot of data" into "here's what we should do." SQL and Python are his go-to tools, but the real work happens in the space between a chart and a decision.
Outside client work, he's usually poking around public datasets — Indonesia's economy, social trends, anything with an interesting pattern hiding in it.
Notes on picking the right chart for the question, not the other way around.
