Tech With Tim

Here’s a full 3-hour data structures course built for real use. I'll walk you through the core topics in a way that actually helps with technical interviews and problem solving. So if you want a stronger foundation for interviews, LeetCode, or CS, watch this video.

This is a full course on prompt engineering. You'll learn what makes a prompt good, which techniques matter most, and how to get much better outputs from the same model. So if you want to make AI a lot more reliable for real tasks, watch this video.

stop keeping projects on your machine and start shipping them for real users

Let me show you how to build a Discord bot in Python from scratch. You'll learn how to set it up, connect it to your server, and add features like commands, roles, polls, DMs, and message filtering. So if you want to learn Python by building something real and interactive, watch this video.

Did you know you can flatten any nested list in Python with one line?

This video shows you how to use Claude Code from scratch. You'll learn how to set it up, use it in the terminal, connect GitHub, and actually build projects with it. So if you want to build with Claude Code without feeling lost, watch this.

The AI Dev System That Enterprise Teams Are Actually Using

Here's everything you need to know about NumPy. You'll learn how arrays work, how to manipulate them, and how to use NumPy in real Python workflows. So if you want to build a stronger base for AI, ML, or data work, watch this video.
