About This Site
This site is a collection of practical tutorials, reference guides, and professional playbooks built from real experience in analytics and data science. The goal is straightforward: provide information that's clear, concise, and immediately applicable — whether you're scoping a dashboard project, debugging a query, building a model, or preparing for an interview.
Most online resources bury the answer under excessive detail, conflicting opinions, or outdated examples. This site tries to do the opposite. Each post is designed to be something you can open, use, and close — without wading through noise.
Beyond the Data
When I'm not blogging or upskilling my analytics skill set through continuing education, I'm probably training Muay Thai or Jiu Jitsu, watching anime, grilling, hanging with family, or spending time with my cat Pashka — also known as Taco — or traveling somewhere new.
The photo reel on the landing page gives you a taste: Japan (three times and counting), Israel, Amsterdam, France, Argentina, Brazil, Australia, New Zealand, Ireland. Travel keeps perspective sharp and curiosity high — two things that make for better analysis, better questions, and better work.
