Nandan Nilekani's appointment on Sunday to head the Narendra Modi government's new exam-reform task force follows a pattern that goes back around two decades. Successive governments, of different parties, have brought him back for technology-policy work. In that sense, it's only the latest turn in a career that has now spanned both the Congress and BJP.Nandan Nilekani, co-founder of Infosys and founding chairman of the UIDAI that brought in Aadhaar, speaking at a conference in Norway in April 2026.

A fresh petition in 2025 argued the underlying problems it was meant to fix had never really been addressed by the government.The NEET-UG leak this year led to mass protests led by the Cockroach Janta Party, forcing Dharmendra Pradhan to resign as education minister, and PM Modi to take steps such as forming the panel with Nilekani,Going back to AadhaarBorn in 1955 in Bengaluru (then Bangalore), Nilekani studied electrical engineering at IIT Bombay, and in his first job at a company met NR Narayana Murthy. The two of them, with others, started Infosys in 1981. He would go on to run Infosys as CEO from 2002 to 2007 and chair its board in various capacities since.He was the founding chairman of the Unique Identification Authority of India (UIDAI) in the rank of a cabinet minister from 2009-2014, his Infosys profile noted. His high-profile work with the government sector indeed started after the idea for a national identity number came up during the Congress-led UPA era in 2006 under PM Manmohan Singh, conceived as a fix for leaky subsidy programmes. The UIDAI was constituted under the Planning Commission in January 2009, and Nilekani was hired that June for the execution of what came to be known as Aadhaar.He went on to also chair the Technology Advisory Group for Unique Projects (TAGUP), tasked with the IT architecture behind the tax network and the pension system.In 2014, the technocrat tried to become a politician too. He quit the UIDAI to contest the Bangalore South seat on the Congress ticket. He lost to the BJP's Ananth Kumar.Work with ModiAs Narendra Modi became PM, economist Montek Singh Ahluwalia has said, Aadhaar was in danger of being shelved given the BJP's opposition to it while out of power. Nilekani reportedly got a meeting with the new prime minister and made his case in person; Modi heard him out in June 2014, and Aadhaar was folded into his governance model.Two years on, after the demonetisation of high-value notes, PM Modi brought Nilekani onto a committee mapping India's path towards digital payments at scale. “India has the underlying digital financial architecture in place to get this going,” Nilekani said at the time.When Aadhaar drew fresh fire in 2017 over being made mandatory for tax filings, he told HT: “Demonising Aadhaar is not going to solve any problem.”He served on an RBI committee too — the High-Level Committee on Deepening of Digital Payments, from January 2019. The commerce ministry added him to its Open Network for Digital Commerce council in 2021, the government's attempt to loosen Amazon and Flipkart's grip on Indian e-commerce.
