Risk signals and follow-up in one view

I turn operational data into clearer decisions.
I work between data analysis and building the tools around it—Power BI dashboards, Power Apps, and the small fixes that keep them useful.

HOW I WORK
I like the work after launch, too.
Most days, I’m updating or checking data, correcting app inputs, looking into bugs, and making small UI/UX improvements. Those little things add up to tools people can rely on.
✳ Make and mend things together.
Check the data
Update reporting, correct input issues, and look into numbers that seem off.
Fix the small things
Catch bugs, make minor fixes, and keep dashboards and apps running smoothly.
Make it easier to use
Refine Power Apps forms and dashboard UI so the right information is easier to read.
A LITTLE ABOUT ME
Make and mend things together.
I’m David—a Jakarta-based analyst and junior programmer. I like getting hands-on, understanding how a process works, then making the data or tool a little clearer for everyone using it.
