After just a month as chief development officer at Skype, Madhu Yarlagadda has left the company for personal reasons, a company spokesman said on Wednesday.

Mr. Yarlagadda’s responsibilities at Skype included running engineering for all of its products, and his sudden departure comes on the heels of Skype’s initial lurch toward a public offering.

Before joining Skype, Mr. Yarlagadda worked at Yahoo as its vice president for engineering on a variety of products, including the company’s worldwide home pages.

Mr. Yarlagadda was anonymously savaged last month in the comments section of a post on TechCrunch about his move to Skype.

The comments caught the attention of Skype executives who became concerned about their new hire, according to a person with knowledge of the situation who was not authorized to speak with the news media.

Mr. Yarlagadda did not immediately respond to an e-mail seeking comment.

Update: TechCrunch reports that Mr. Yarlagadda’s wife threatened legal action over the comments last month.
