What I'm looking for

I’m looking for roles where I can combine structured, hands-on project delivery with strong marketing thinking—and apply my quality-first approach to data and content. I value collaboration with creative teams and clear client goals.

I’m an experienced project and marketing manager with a hands-on mentality, skilled in taking projects from concept to completion while keeping the client’s goals in mind. I’ve built a track record in developing strategies and producing marketing content, videos, and websites with creative teams.

Currently, I work as an AI Data Annotation Specialist, analyzing guidelines to enhance AI performance, assessing sensitive queries, and engaging in consensus discussions. I bring a detail-focused, quality-first approach to every task and collaboration.

As a business owner, I handle overall management, including sales, producing, project management, and optimizing team performance. I’ve also led PR & Communications Strategy work and brand positioning, media relations, brand activations, and budget management & ROI, and I’ve contributed to teaching entrepreneurship, consumer behavior, and online marketing.
