I am Kyumin Han, doing a BeReal Product Management Externship while I gain practical product experience and shape my career path.
I am Kyumin Han, a computer science and mathematics student at Pepperdine University with a data science minor. I have built backend and full-stack systems, from an Airflow ETL that polls the Spotify API to a 3D star map using astronomy-engine and a volleyball play recognition app using custom YOLO models. My roles have included software and BI internships, applied AI research, and IT analysis while I complete my degree and a BeReal product management externship.

Discover how product teams at social apps like BeReal design for authenticity while driving user growth. In this externship, you’ll explore what keeps users coming back— benchmarking competitors, analyzing engagement features, and designing your own growth-driven app feature. You’ll learn how to balance product innovation with BeReal’s unique mission of real, unfiltered connection. Perfect for those interested in product management, UX strategy, or social media innovation, this experience gives you a hands-on look at how product teams grow platforms without losing their core values.
The externship examined how social apps balance authenticity with growth by benchmarking competitor engagement features and designing a feature concept for BeReal. Work compared product patterns across platforms, analyzed engagement mechanics, and produced a feature proposal that reconciled growth-focused mechanics with constraints on authenticity.
I analyzed competitor features, evaluated engagement mechanics, and designed a feature concept for BeReal. Below are the discrete deliverables I produced during the externship.
