As Head of Marketing at OY! Indonesia, our Founder established a full marketing function—from social media and content to design, digital ads, and event videos. This included establishing the brand's image, voice, and tone to ensure consistent communication across all channels.
The role also involved operational leadership: building reporting systems, managing tools, overseeing staff performance, and supporting recruitment and training. These efforts laid the foundation for a cohesive marketing team and strengthened OY!’s visibility in Indonesia's digital ecosystem.
