To understand what drives students to book a tutor,
I conducted in-depth interviews with Buki users and one who actively searches for tutors.
After 15 user interviews, I developed a solution to make photo bigger without burdening tutors—by enlarging the photo size, making it mandatory, and providing clear photo guidelines.

Since photos played a critical role in how students chose tutors — I added subtle tips with clear guidance for tutors. These suggestions explained the importance of a good portrait and encouraged tutors to upload high-quality photos.
Results
We uncovered what drives students to book: trust, clarity, and strong visuals.
By refining existing elements—like photo presentation and profile layout—we significantly improved decision-making without adding friction for tutors or students.
