His areas of expertise include Banking and Finance Law, Corporate Law, Commercial Law, Real Estate Law, Contracts Law, Tax Law, and IT Law, which has become one of the key legal fields of the digital business era. Designing contractual processes for corporate structures, ensuring regulatory compliance in tax and real estate investments, and developing practical and sustainable solutions in disputes are among his main areas of focus.
