William specialised in content aggregation, scheduling and forecasting for Persuasive Networks in HK/SG, assisting with market research, branding, acquisitions, copywriting, promotion, presenting and co-production for both luxury lifestyle and educational Pay TV channels in the Asia-Pacific rim. He also was strategy advisor to the direction of a full-service digital media agency Overall-Media, in video content management solutions (CMS) observing Catch Up TV, VOD and 360-degree strategic deployment, convergence technologies and distribution needs in multi-platform or IPTV products.
Since 2013 William founded a casting agency fervently committed to talent ethnic and linguistic diversity, disability and LGBTIQ+ inclusiveness with his partner Michael Turkic, touching the raw nerve on issues of equality, opportunity, fidelity and representation. He has spoken at various seminars, presentations, workshops and conferences.
In 2014-2015 William was DON'T Dis My ABILITY Ambassador for the NSW Government Family & Community Services. He raised awareness for access requirements, politically correct language and social etiquette while offering hilariously unique insights into Deaf and Hearing Impaired culture.
William contributed to the 2017 Australian Marriage Equality Campaign with his grandmother (famous TV chef/food sculpture artist in Vietnam). That same year, he was also storyteller for director William Yang's "Who Speaks for Me?" sharing the stage with his mother and grandmother, and alongside two other Asian families about miscommunication, identity and migrant diasporas. A five-show debut at Riverside Theatres Parramatta, it received much praise from the audiences for its tear-jerking, anecdotal relatability and authenticity.
In 2021 William was a successful resident of Australia Council's "Future Leaders Program", learning about the resiliency and merit of leadership in modern, amorphous times.
