From a Developer's Notebook: The Story Behind CodeRepeat

My name is Keshav, and I'm a full-stack developer. For years, I've been building web applications and Python projects, but I had a nagging problem that I was almost too embarrassed to admit: I kept forgetting some basic syntax. I'd find myself searching for how to write a simple JavaScript `reduce` function or a Python list comprehension, even though I'd written them hundreds of times before. It was frustrating and felt like a huge drag on my productivity. I started talking about it online, on forums like Reddit and on X, and I was shocked to find out I wasn't alone. So many other developers, from beginners to seasoned pros, shared the same struggle. This problem is even more daunting during the AI agentic era where the AI agents can write a whole application with several thousands of lines in a few seconds or minutes, making space for coder and developer to forget fundamental building blocks of programming languages.

That's when I decided to build a solution, not just for them, but for myself. I poured countless hours into creating CodeRepeat, an application designed specifically to tackle this problem. The core idea was to move beyond just knowing the code and to start training the physical act of writing it. I wanted to build a tool that could help us develop real muscle memory, so that the fundamental building blocks of our favorite languages would flow from our fingertips without a second thought.

I've been using CodeRepeat myself as its first and most dedicated user. I've been regularly practicing snippets for everything from python list comprehensions to asynchronous JavaScript patterns. The difference has been night and day. I feel more fluent and efficient when I'm working on my personal projects, and I spend far less time breaking my flow to look up things I already know. I built this application because I needed it, and I'm sharing it because I know so many of you do too. I truly hope you make use of it and that it helps you become the confident, fluent coder you deserve to be.
