Data Analyst

Hi, I'm Ralph Jieian Sebastian.

Data Analyst who leads and builds.

I analyze data, lead teams, and build software, all in service of one thing: clearer decisions.

Data isn't the answer. It's where better questions begin.

I'm drawn to data analytics because better decisions start with better understanding. I like looking past the numbers to find the story they tell, question assumptions, and spot what could actually be improved. Whether I'm analyzing data, leading a project, or building software, the goal is the same: make the decision clearer than it was before.
