Building a better working world
“Companies today are operating in a fast changing business environment, while the transformation of international taxation is on a scale only seen once in a century. In response, companies are required to take immediate action, including reviewing their tax positions, improving tax governance, streamlining tax operations through the use of technology, and preparing for new disclosure requirements.
I aim to contribute to enhancing corporate value and competitiveness by leveraging EY’s knowledge and skills in tax and other areas, as well as our global network, to help our clients navigate these challenges.”
