What I'm looking for

I’m looking for a role where I can use data cleaning, modeling, SQL, and dashboards to drive real decisions. I want to keep learning, deliver measurable impact, and contribute to a team that values quality and continuous improvement.

I’m a multi-dimensional professional who turns messy information into clear insights through innovation and continuous learning. In my Data Analyst experience (SIWES), I focused on Data Cleaning, Data Modelling, and Visualization to support better decision-making.

I also build quality AI-ready data as a Data Annotator by training AI models and ensuring accuracy by following Economics guidelines. Alongside analytics, I’ve supported teams as a Virtual Assistant and Office Manager/Personal Assistant—handling Excel workflows, Tableau/Power BI reporting, SQL, customer relations, and reliable record keeping—so operations and insights move forward together.
