About Ezra

I am an Informatics student at Petra Christian University with a 3.76 / 4.00 cumulative GPA. I build AI-assisted and full-stack products for students, young builders, and early-stage entrepreneurs.

I turn messy workflows into clearer decisions and usable systems. My proof spans live commerce, an award-winning workforce-allocation prototype, a full-stack event platform, and an accounting SaaS experiment. I am open to software/AI internships, collaborations, and product-engineering work.
