Prior to his work in the private and public sectors, Nayak served in the World Bank Group. He joined the Group in 2000 as a Young Professional (the Bank Group's internationally competitive leadership program) and served in various parts of the Bank Group, including the International Finance Corporation (IFC), the International Bank for Reconstruction and Development (IBRD) and the International Development Association (IDA). He voluntarily exited the World Bank Group in 2015.
Nayak's contributions in the World Bank was confined to Europe (Eastern and Southern), Asia (Central, South and East) and America (South). Among his notable contributions, was the designing and establishing of the economic architecture of Kosovo that served as the foundation of Kosovo as an independent entity. It set the stage for Kosovo's independence on 17 February 2008 and the enforcement of its constitution in June 2008.[6] He has played an important role in facilitating the process of Kosovo's membership at the World Bank.[7] Kosovo became the newest member of the five World Bank Group institutions on 29 June 2009, when Kosovar President Fatmir Sejdiu and Prime Minister Hashim Thaçi signed the Articles of Agreement of the International Bank for Reconstruction and Development and four other agencies of the World Bank Group.[8]
Nayak contributed to regional development in the Western Balkans including in Serbia, Croatia, Bosnia Herzegovina, Montenegro, Albania and North Macedonia.[9][10][11] In his World Bank tenure, he helped finance development solutions in the areas of post-conflict reconstruction, employment of best practices, strengthening of public institutions, and promotion of effective governance.[12][13] Nayak helped invest development funds to developing sectors as banking, finance,[14] energy,[15] mining,[16] climate change[17][18] education,[14][19] and transport.[20]
Nayak was involved in the development of dialogues in high-level forums[21][22][23][24] in partnership with agencies such as United States Agency for International Development, the European Commission, the International Monetary Fund, bilateral and multilateral agencies, and NATO (KFOR).[10] He was an advocate of democratic and multiethnic institutions in areas featuring ethnic tensions.[25] He supported positive interventions among the youth[26] and the physically challenged in economic development.[27] He articulated on these issues in the European lecture circuit.[28][29] In an interview with the BBC, he stressed the vulnerabilities of global economic shifts and financial crises on local economies, through he remained optimistic about the future of small-sized countries.[30]
Nayak has published in the areas of resettlement and migration, post-conflict reconstruction, informal labor market,[31] youth, corporate social responsibility, forestry, food policy, indigenous peoples, governance, and human rights.[32][33][34][35][36]
Prior to joining the World Bank, Nayak served as: a Consultant in the United Nations Human Rights Commission in Geneva (Switzerland); a tenured Assistant Professor in JNU in New Delhi (India); the Research Director of FIAN (Food-First Information and Action Network) in Heidelberg (Germany); a Researcher in the Institute of Development Policy and Management in Manchester (United Kingdom), among others.
Nayak's contribution to the stability of post-conflict areas is considered substantial. He has served in Afghanistan, Albania, Iraq, Kosovo, Nepal, Russia and Sri Lanka during periods of armed conflict. He raised $1.5 billion in donor funds towards Kosovo's first budget as an independent state in 2008.[37][38]
While serving in local, national and international NGOs, and later in the World Bank, Nayak worked on addressing issues surrounding poverty in South Asia, South America, and South Eastern Europe with the IMF (International Monetary Fund), EC (European Commission) and bilateral government agencies such as DFID (Department for International Development of the UK Government) and KFW (Kreditanstalt für Wiederaufbau, Germany). He attempted to integrate "macro" and "micro" - economic and social reform.[39][40]
Nayak has founded a global renewable energy company that focuses on BESS (Battery Energy Storage System) and photovoltaic power stations. The company owns about 200 international patents, 1.8 Gigawatts of solar power and 1.5 Gigawatt hours of BESS. These results are based on company operations since 2019. In parallel, Nayak discusses policy issues in various forums relating to climate change adaptation and its mitigation.[41][42][43][44]
Nayak has worked on systemic corruption and unjustified public expenditures in government institutions that hinders economic growth and keeps citizens in poverty. In an investigative report in Foreign Policy in 2010, Nayak is alleged to have positioned himself against the interests of a corrupt government as the World Bank Representative. The alleged corruption scandal was on a major East European highway. The report indicated the absence of a commitment to good governance by the Government and the private construction companies that were involved in the project.[45]
Nayak is recognised for his contribution to knowledge and innovation through citations. In one of his public speeches on education, he argued that education policies should promote overall learning for young learners that goes beyond classroom-based learning integrating it with learning from peers, family, community, a variety of institutions, and the social space .[46][47] Nayak has led research on guiding South European countries to improving the environment for fostering cutting edge innovations. A World Bank paper published in 2011 on Regional Research and Design Strategy for Innovation in the Western Balkan Countries, which Nayak has guided, identifies key issues and implication of technical assistance.[48][49]
Nayak has published on exploitative informal labour, particularly on harmful child labour, for the International Finance Corporation. Nayak discusses the implication of such labour in the private sector and how private companies can detect it in their supply chains and address it towards sound labour practices. This is considered good practice for private firms.[50]
Nayak has researched and published on refugees and displaced populations and ecological habitats. His proposition is that the forced dislocation of human, animal and plant ecosystems due to the execution and establishment of large infrastructure projects cannot easily offset: the loss of livelihoods, destruction of living ecosystems, and adverse mental and physical traumas. Hence, these projects must be thought out from all dimensions including ethical ones.[51][52][53]
During his career in Southeastern Europe, Nayak campaigned for the inclusion of minorities of all types – economic, social, ethnic, religious, linguistic, and gender, in development projects. An example of his initiative was in 2011 in the Western Balkans, when he found an innovative way of working against the discrimination of minority Serb communities by the majority Albanian communities by incentivising micro-development programs that enabled both communities to work together for shared financial and economic gains. In the long run this has fostered peace that has been sustainable.[54][55]
Nayak is an advocate for the inclusion of economically, socially and politically disadvantaged minorities in the broader development and welfare schemes. He is the co-author of a report on the Roma in Bulgaria entitled "Gender Dimensions of Roma Inclusion" that serves to guide national policy on social inclusion in Bulgaria. The study reveals the complex relationship between minorities and majorities within the European Union, and how the understanding the internal worlds of minorities and discriminated groups is a first step towards effective policies and programmes.[56]
He is the recipient of the World Bank's Corporate Diversity and Inclusion Award in 2006 after he led the recruitment of the Bank's most diverse Young Professionals ever in its history since 1961. Nayak devised innovative ways to identifying talent globally. Here is an example of his work in Sydney, Australia.[46][57]
Nayak is an exponent for a value-oriented global arrangement that focuses on economic growth, quality of life, and environmental sustainability, while incorporating values that underline morality, ethical economics and adverse climate mitigation. His position is captured in an invited talk on "The Economy of Tomorrow" organised by FES (Friedrich Ebert Stiftung in Germany) and NISWASS (National Institute of Social Work and Social Sciences in India).[58] Nayak argues that the sharing of good, ethical, moral and humane values should be an intrinsic part of our socialisation and learning across formal and informal institutions. This would help us shape a better human future.[59][60]
