Hi, I'm Aravind.

I turn Sydney's public data into answers you can trust. Here's what I've been building.

Tested before it shipsData checks and automated tests catch the wrong numbers before anyone sees them.

Know a team that needs a data engineer?

I'm finishing my Master of IT at UTS in December and looking for junior data engineering, analytics and cloud roles in Sydney from early 2027. An intro, a referral or a quick coffee chat would mean a lot.
