Michael Y

Michael Y Agency Contractor

Sr. Systems Architect, Mathematician-Astrophysicist and Bio-Geneticist

Canada - Tests: 2 - Portfolio: 5

My purpose is to lead, strategize, guide, direct and architect problem resolutions for individuals and organizations using self-sustainable philosophy and decision-making, in order to establish complete systems and processes of solutions that work. My vision is to ensure in every household, institution or establishment, intuitive and organic integration of real-time problem-solving becomes second-nature to the operating environment. I intend to achieve this using my unparalleled knowledge and application of the Synergy between Business Intelligence, Technical Excellence and Organic Sustainability. In other words, I solve problems, using fundamental building blocks that most people and organizations overlook, yielding solutions that can adapt to their environment in real-time. Problem-solving processing can lead multiple resolutions to several problems whereas "a solution" to a problem itself only, usually yields a new problem that need be solved with other solution(s) which may or may not be found within the given scope. This cycle can be vicious and critical but is easily overcome by what we call the "Process" or "Spiral" at Don Sigma Corp. This so-called "Spiral" allows us to solve problems that solve other problems by drawing Synergy between resolutions and fundamental building blocks. With this know-how and several other particulates of Don Sigma Corp.'s unique knowledge and technology at my disposal, you're just a contact away from experiencing your dreams come true.
