I’m a digital marketing and AI data annotation professional with 5+ years of experience spanning brand planning, social media operations, KOL collaboration, e-commerce management, and multimodal AI task execution. I enjoy bridging human-centered communication with data quality that directly supports model training workflows.

As a Marketing Specialist at Li Design Studio, I led digital marketing initiatives, developed advertising copy, and managed social media content across multiple platforms. I coordinated influencer (KOL/KOC) campaigns to increase brand awareness, maintained e-commerce website backend operations and product management, and managed customer service response systems to keep client communications timely.

In my AI Data Annotator role, I executed AI data annotation and generative task workflows for multimodal data processing. I handled LVM/VLM tasks such as bounding box annotation and image classification, supported AI training data preparation for image and video generation models, and performed real-time recognition response and visual question answering (VQA).

Earlier, I worked as a Digital Marketing Specialist at Ishikawa Media, where I managed advertising campaigns, SEO optimization, and website traffic analysis. I planned marketing campaigns, created and scheduled social content and EDM newsletters, supported KOL sponsorships and group-buying promotions, and also contributed through order fulfillment—keeping execution reliable from campaign launch to delivery.
