About Me
Byeongsoo Kim
Full-Stack Product Engineer
Hamburg, Germany
Background
I've spent 13+ years building software in various roles — engineer, product manager, and solo founder. The common thread: I'm happiest when I own problems end-to-end and ship solutions that measurably help users.
Currently, I work as a Full-Stack Product Engineer, shipping production tools autonomously across teams. My PM background means I understand users deeply before writing code.
I hold a Master's degree in Computer Engineering from KAIST (Korea Advanced Institute of Science and Technology).
What I Build
I create focused tools designed around the principles of deliberate practice — valid environments, many repetitions, timely feedback, and intentional growth.
