I started my career at a consulting firm with experiencing growth strategy, new business development and business turnaround, and I became an independent consultant. While working as a management consultant, I realized that recruiting and human resources are the most effective for corporate management.

While providing recruiting services, I contributed to the expansion recruiters from 5 to 60 recruiters. After leaving the boutique recruitment agency, I ran my own business. During this time, I have contributed to building a business foundation centered on expanding new customers at ICPA. October 2018, I fully joined ICPA.
