Taranjeet Singh, who was appointed Twitter’s Country Director for India last year, is quitting the company. Singh announced his decision to move on in a series of tweets later Tuesday.

He said Balaji Krish, Twitter’s Global Head of Revenue Strategy and Operations, would take over as the interim country head.

Taranjeet Singh was elevated to the position of Twitter’s India head in May 2917.

“Hello everyone, after four amazing years, I have decided to move on from @TwitterIndia — from being one of the first @Twitter employees in #India, to building up the sales team from the ground up, to leading our expansion and investments as the India Country Director,” Singh tweeted.

Singh earlier led the charge for sales and marketing support for Twitter’s advertisers in India.

“India is one of our largest and fastest growing markets worldwide today. We have hired many Tweeps at @TwitterIndia, diversified our client base across the country and continue to be the pulse of Indian society,” he said.

Prior to Twitter, Singh was sales director, South Asia for BBC Advertising. Earlier, he had been with Outlook Publishing.

“I’ll spend the next month transitioning my country duties to colleague and friend @BalajiKrish, our global head of revenue strategy and operations.

“He’s coming from the US to be interim country lead until my replacement is hired,” Singh said in one of the tweets.

During his career in India, Singh has worked towards establishing Twitter’s alignment with the government. The micro-blogging platform is now working with the government on real-time citizen engagement through “Twitter Seva”.

“As an India-first innovation, ‘Twitter Seva’ is currently being used by the Ministry of Commerce (@DIPPGOI), the Ministry of Railways (@RailMinIndia) and the Department of Telecommunications (@Dot_India) under the Ministry of Communication,” Singh had told IANS earlier.
