David began his career in broadcast and print journalism in Singapore in 1996.  In 2000-2001, he worked as the creative director of GetIT Multimedia, a Silicon-Valley-headquartered start-up company specialising in rich-media-applications and e-learning in the Asia Pacific.  Subsequently, as the chief knowledge officer of the Raffles International hotels & resorts group in 2001-2003, David facilitated the knowledge capital integration of the newly-acquired Swissôtel and Resorts chain with the Raffles Hotels and Resorts.  His strategy enabled the corporate group to win the Intelligent Enterprise 20 Award (2002), impressing judges from 10 world class IT research and management consulting firms, namely, Accenture, Atos Origin, Braxton, Frost & Sullivan, Gartner, IDC, KPMG, META Group, Ovum, and PwC Consulting.  Recognising how emerging new Internet technologies could influence the ways information and guest services were provided in world class hotels and resorts, David pioneered the first in-house "Information Literary" staff training workshops for the Singapore hotels sector in January 2004.  

In 2004-2005, David was appointed as Senior Consultant to the Singapore Workforce Development Agency (WDA) and Ministry of Manpower (MOM), where he facilitated national workplace strategy development for industry and promoting workplace leadership in the Tourism and Hospitality, Healthcare, Retail, Aerospace (MRO) and Logistics (Services) industry sectors respectively.

He authored WDA's pioneering strategy for "Cultivating Communities of Practice and Visualising Great Workplaces" (08 Oct 2004), which broadened the thinking and conversations of policymakers about inter-agency cooperation, collaboration with industry stakeholders, and public consultation, while creating value by identifying new avenues for researchers to collect, analyse and share qualitative data in an increasingly "social" and unpredictable economy.
