I Shipped a Facebook Feature So Fast Sheryl Sandberg Called an Emergency Meeting

6 hours ago

A software engineer at Facebook built a file upload feature for Facebook Groups over a single weekend, directly messaging Mark Zuckerberg and insisting it would be ready by Monday.
The feature was implemented by creatively reusing existing internal systems like Haystack for storage and integrating with site integrity tools for security, enabling rapid deployment despite initial executive skepticism.
The launch required an emergency meeting with top executives including Sheryl Sandberg due to concerns about copyright infringement and security risks, but the engineer addressed these by adding safeguards.
The story highlights Facebook's culture of extreme ownership at the time, where engineers had the autonomy and responsibility to drive projects from idea to deployment, even defying leadership.
The author reflects on whether modern AI-driven development, which automates much of the 'glue-work', might erode the sense of ownership and courage that empowered engineers to take such bold initiatives.
