What I'm looking for

I'm seeking CRM and customer insight opportunities.

At United Arrows Taiwan Ltd., I analysed purchasing behaviour across a 200,000+ member base and identified retention opportunities through lifecycle segmentation. I also led a loyalty programme redesign using customer data, stakeholder interviews, and Taiwan–Japan benchmarking.

Through targeted campaigns and push notification optimisation, I increased app revenue share from 35% to 55% and grew app active users by 29%. At MiTCH Co., Ltd., I used sales analysis and commercial planning to achieve 122% sales growth across a portfolio of Japanese fashion brands.
