Summary
👤
SeniorJulien Kmec is a software engineer and founder with nine years of experience who built Bloxlink as a college freshman and scaled it to 90M+ users and 1M+ communities before it was acquired by Roblox in 2024. Now at Roblox, he focuses on first-party communities and led the end-to-end development and release of the "Ban User" feature used by millions.
