About Me

Hi, I'm Tariehk, a data analyst who discovered a passion for analytics while managing my own business. My journey into data visualization began when I needed a better way to understand sales trends and make informed decisions. I turned to Tableau, and its powerful visualizations helped me uncover insights like identifying peak revenue periods, tracking sales patterns, and optimizing strategies for success.

Since then, I've created a variety of visualizations that provide actionable insights, including:

  • Analyzing customer demographics to fine-tune target audience strategies.
  • Measuring marketing campaign performance to boost ROI across multiple channels.
  • Developing dashboards to track inventory trends and enhance supply chain efficiency.
  • Creating year-over-year sales heatmaps to highlight seasonal opportunities and drive growth.

For me, data is more than numbers—it's a tool for solving challenges, telling impactful stories, and delivering results. I'm excited to share my journey and expertise to help others unlock the full potential of data.
