My name is Paul Karol and I work as a director in a Russian IT company that mostly sells their products in the international market.

Amazon parsing on easy level and all by yourself

Level of difficultyEasy

I came across a script on the Internet that allows you to parse product cards from Amazon. And I just needed a solution to a problem like that.

I wracked my brain while looking for a way to parse product cards from Amazon. The problem is that Amazon uses different design options for different outputs, in particular – if you need to parse the cards with the search query "bags" – the cards will be arranged vertically, as I need it, but if you take, for example, "t-shirts" – then the cards will be arranged horizontally, and in such way the script falls into an error, it works out opening the page, but does not want to scroll.

For one of my projects I was exploring Reddit to understand how players create characters in video games, what is important to them in this process, and what their preferences are. It turns out that communities sharing their creations or seeking help with specific character designs remain active even for games released years ago. This realization sparked the idea for a hobby project that could assist these players in creating the characters they envision.

At some point while diving deeper into automation processes you are faced with the need for data labeling, although just a couple of weeks ago, the phrases data labeling and you were standing at a party called "Earnings on the Internet" in different rooms. Or it would be better to say that you were standing by the pool, and the data labeling was on the third floor, smoking on the balcony with experts in the field of machine learning. How did we meet? Probably, someone pushed it off the balcony into the pool, and I helped it out, soaking my clothes along the way.
