With over 20 years of experience at the intersection of finance, IT, and tax compliance, I’m passionate about transforming how global organizations manage tax and regulatory complexity through technology.

As the Founder of Taxera Technologies, I lead a global team building a cutting-edge cloud tax platform designed to be the world’s leading tax technology solution — empowering multinational businesses to simplify compliance, enhance transparency, and drive operational efficiency.

Throughout my career, I’ve led complex, cross-industry transformations across FMCG, pharmaceutical, automotive, and telecommunications sectors — optimizing business and tax processes, ensuring alignment with evolving reporting standards, and leveraging digital capabilities to scale impact.

As both an entrepreneur and leader, I’m driven by a vision to reshape the tax landscape through innovation, compliance excellence, and collaboration. At Taxera, I’m proud to lead a talented and diverse team of professionals who share my mission — to make tax technology smarter, simpler, and more human.
