Class of the Process

"Tortoise, Calico, sometimes known as the 'divas' of the feline world " From Repetition to Reusability: How I Ended Up Writing My First Class In my data projects, the biggest hurdle was always the time it took to prepare the data and get it ready for analysis. After writing the same code over and over again—with only minor changes each time—I realized it was time to create a function (or a small collection of them) and just call it when needed. It made sense, since the overall procedure didn’t vary that much. So, I got started. At first, all these functions lived inside main.py . But as the project grew, that file became bloated and harder to manage. I quickly realized how important it was to keep main.py clean and simple so I could easily control and understand my workflow. That’s when the need for a class became obvious—and the journey toward better structure and reusability began. Enter DataProcessor : A Modular, Reusable Utility for Data Cleaning And th...

Soft introduction - Data Preparation

Introduction A while ago, I started a store manager position at a medium-sized business specializing in high-quality wine and liquor. This happened a few years after I had completed my MSc. The physical store, with a little effort, was set up just the way I wanted it, and alongside my other responsibilities, I also had to manage the accounting part. These involved long, repetitive calculations, which I needed to automate to save time for more important tasks. To address this, I created a spreadsheet in Excel that significantly improved my workflow. In addition to streamlining operations, this system also generated a large amount of data! And it didn’t take me long to realize that I had to do something valuable with it! Data Preparation For data science projects, the quality of the available data is critically important. Are there any missing values? If so, how should they be handled? Are the numerical columns truly integers or floats, ...

Hello, world!

It's been a long time since I created this page, and I thought—why not give it a new purpose? From now on, among others, I'll try to upload Data Science and Machine Learning topics as frequently as my obligations allow!
