Most of my channel is Java and Spring Boot. For this video I wanted a break, so I built something in Python that a complete beginner can finish in one sitting: a to-do app with a real REST API, a real database and a web page on top. It comes to three files and under 130 lines of Python. This post is the written companion to the video. Every code block below is copied from the project, and I ran every request in it against that code before publishing. If you prefer to read, you can build the whole thing from this page. If you prefer to watch, the video is right here. What you'll build A to-do list where you can add a task, tick it off, rename it and delete it. The page talks to an API you write yourself, and the API saves everything in a database, so your tasks are still there after a restart. FastAPI also gives you a free interactive docs page at /docs where you can test every endpoint from the browser. File Its one job index.html The to-do page, styled with Bootstrap. I...
Backend Deep-Dive · Beginner Friendly ~16 min read · Updated for 2026 · No prior experience required If the words Kubernetes and EKS have always felt like a wall of jargon, this is the guide that finally makes them click. We start from absolute zero — what a container even is — and build up, one idea at a time, until you can follow a single user request all the way through a real Amazon EKS cluster and back. Plain English, simple analogies, and a clear mental model instead of a pile of commands. Prefer to read? Everything in the video is written out below. Skim the table of contents and jump to whatever you need. TL;DR — the whole idea in six lines Containers pack your app and its environment together so it runs the same everywhere. Kubernetes is a manager that runs, heals, scales, and connects hundreds of containers for you. Every cluster has a Control Plane (the brain) and Worke...
