This work resulted in the development of a multimillion-dollar programme in support of parliaments and political parties in the Arab Region, funded by the Government of Belgium. In 2012 Deveaux was one of the first international experts to assess the Assembly of the Union - the Parliament of Myanmar - meeting with the leaders of all the major parties in the parliament and recommending significant interventions in support of the institution. Deveaux was also instrumental in the creation of social media portals which promote parliamentary development and the political empowerment of women - namely, Agora, a web portal developed by UNDP, NDI, the World Bank, the European Commission and the International Institute for Democracy and Electoral Assistance (International IDEA); and the International Knowledge Network of Women in Politics (iKNOW Politics) website, which promotes the participation of women in the political process. In September 2012 Deveaux completed his assignment with the United Nations Development Programme and created Deveaux International Governance (DIG) Consultants Inc. , a firm focusing on the provision of technical advice to parliaments, political parties and organizations that work with these political institutions globally. Since the firm was created, Deveaux has worked with the World Bank, International IDEA, UN Women, UNDP, the European Union, USAID, the Swiss Agency for Development Cooperation and other organizations. From 2013-15 Deveaux was part of team contracted by DFID to conduct a series of evaluations of the Westminster Foundation for Democracy. Deveaux has worked directly with more than 50 parliaments and MPs from more than 110 countries. He has formulated more than 20 parliamentary development projects including in Serbia, Tanzania, Tunisia, Uzbekistan, and South Sudan. He has provided technical assistance to numerous parliaments, with more recent work including Malaysia, Georgia and Lebanon. In particular he has been engaged since 2013 in re-establishing the Parliament of Fiji, including the writing of the Standing Orders and other relevant legislation and support to the Law, Justice and Human Rights Committee. Through UNDP he has also been engaged in Nepal since 2016, supporting the establishment of seven provincial assemblies after the country adopted a federal political system in 2015. In addition to his work with parliaments, Deveaux has provided technical assistance to political parties in a number of countries including parties in the Western Balkans, Pacific Island States and Southern Africa. He has also authored a number of practical guides and handbooks for parliamentarians on topics such as renewable energy , the Sustainable Development Goals (SDGs) , Climate Finance , Commonwealth Parliamentary Association Benchmarks Self-Assessment Toolkit and the operation of constituency offices.
