Hi, I'm Manh Tuan Do. I recently graduated from San Jose State University with a background in business analytics, and I love using data to answer real business questions: which transactions look like fraud, which models are worth trusting, and what's actually behind the numbers on a dashboard.

This blog is where I write up what I learn, with real results and code you can run.

What I write about

  • Machine learning & AI: building and comparing models, and judging them by metrics that matter to the business.
  • Data analysis & visualization: exploring data and turning it into clear charts and decisions.
  • Project case studies: walkthroughs of real projects, like my credit card fraud detection project.

Skills & tools

  • R
  • Python
  • SQL
  • Excel
  • Tableau
  • Power BI

Open to work

I'm currently looking for data analyst and data science roles. If you're hiring, or you'd like to talk about a project, I'd love to hear from you.
