Lewis is a prolific professional artist who exhibits internationally and helps artistic communities effectively promote their work.
Through the 1980s, he practised professional photography, developing an extensive portfolio of architectural, industrial and fashion work. He also designed and photographed calendars, using glamorous models in exotic locations, as well as fashion photography, which found its way into several top magazines such as Vogue.
He has invented, designed and commercialized several innovative products—for example, he designed, manufactured and brought to market a microwave-shielding device designed to protect mobile phone users from potentially harmful radiation.
He worked in Geneva for the International Labour Organization (the United Nations agency), as a communications specialist for ILO/AIDS—the part of the ILO that deals with HIV/AIDS in the world of work. He went on to consult with several other UN agencies, such as UNAIDS, UNDP and WHO.
He discovered a new way to trade currencies and has been teaching his unique methodology since 2005. LEFT Brain Trading uses a combination of powerful mindset techniques developed by his wife, Olga Sheean, and Lewis’s revolutionary method of setting up trading charts that is based on ancient knowledge and the Fibonacci ratios. He co-authored a book on the subject and achieved worldwide recognition and sales within the first year through web-based marketing, seminars and courses.
In 2011, he published his first novel—Hominine: it’s time to choose—a fast-paced geopolitical thriller that raises important questions about our existence and provides disarmingly simple answers.
He regularly mentors and coaches start-ups and small businesses in Europe and North America.
He provides creative business development services, powerful brand and other workshops, complete marketing communications packages for companies/organizations of all shapes and sizes.
He runs art-based creativity holiday courses in nice sunny locations.
From 2011 to 2020, Lewis was a Board Director of PeaceGeeks, a Vancouver-based non-profit, volunteer organization that builds technological, communications and management capacities of grassroots organizations working on the promotion of peace, accountability and human rights. PeaceGeeks help connect skilled volunteers to these organizations so they can gain access to relevant technology, tools and training.
