About
For more than 25 years I have worked on the taxation of financial instruments, from Samsung Finance Research Institute to university teaching, government tax committees and commissioned research, and I have served as an examiner for the national CPA, tax accountant, customs broker and real estate agent exams. I now also co-run a company building TaxTech that turns tax law into computable rules and a learning platform for accounting and tax certification exams.
