After joining NEC Singapore Pte Ltd, Gideon developed two major applications for the company, Tourism ONE and Hotel ONE, which were among the batch of pioneer applications developed and showcased for Asia Telecom 97. After leaving NEC, Gideon, then 27 only, set up Web Synergies without real plans but at least a bedroom to work from. The company has since won numerous accolades and an award for the United Nations Environment Programme for the Asia Pacific website for its excellence in web development.

In his current position of CEO of Web Synergies, Gideon oversees major government and private sector IT projects, e.g., for Housing & Development Board, Singapore (HDB) and Sony, Merrill Lynch, etc. In addition, he has conducted workshops for the International Trade Institute of Singapore, a subsidiary of IE (Singapore international trade development board), in topics like ecommerce, Electronic Customer Relationship Management and Internet Marketing. The National Youth Achievement Award Council, in recognition of his experience, had asked him to be a judge for a national schools website competition.

Gideon, always a pioneer, was as a teenager among the first 50 members of City Harvest Church, now a 14,000 strong Christian community. He also cultivates with great humility and secrecy a couple of "private gardens".
