Welcome to my website, where I write mostly on tech-related content to share the things I learned from people and from building projects using different tools.
My interests are in tech, traditional finance, cryptocurrency.

In this series, I explore systems programming with rust.
This is a follow-up post from Building redis with CodeCrafters. When I first started the redis challenge, I did the quick and dirty way of bypassing the redis serialisation protocol in order to make things work. Redis serialisation protocol implement...

CodeCrafters is an amazing community built by Paul Kuruvilla that contains project challenges for real-world software systems that are used widely(redis, git, docker, SQLite).
Each project comes in the form of guided steps on what you will build and leaves enough room for you to acquire new knowledge and apply them.
As a follow-up to my previous post on learning Rust, as well as my personal goals of working with technology at lower levels, I tried the Redis challenge with Rust, which is at the beginner level, and had a blast with it.
A starter project is provided to help you get started. Each time code is pushed to the repository, the CodeCrafters server will run your code against its own test cases and the output is streamed to your console.
Here are the steps in the redis challenge.
1. Set up
2. Bind to a port
3. Respond to PING
4. Respond to multiple PINGs
5. Handle concurrent clients
6. Implement ECHO
7. Implement SET and GET
8. SET with expiry
Challenge complete
After completing the first challenge in CodeCrafters, you will get a cool profile page that shows your progress.
As you can see, the challenge comes in a series of tasks that are built on top of the previous ones. Links to learning resources are provided, nothing more than that.
However, if you are stuck on a certain task, there is a discord community in which you can ask for help. The creator himself is very active.
The website also has a useful FAQ bot for general debugging.

I really enjoyed the learning experience that CodeCrafters provides as there is just enough material for me to start learning and building on my own. It is fun, and is the best way to learn a programming language - learn by doing.
The website is super friendly, easy to navigate, easy to get help via FAQ bot and discord.
Going through multiple courses is useful only up to a certain point because many of them hold your hands throughout every step, leaving little room for independent learning.
For people who "don't know what to build", including me, this is a good place to start, and I cannot think of something better.
Overall, I highly recommend anyone who wants to learn a programming language and build a project at the same time to use CodeCrafters.
Here is my completed project on github. Feel free to check it out and leave suggestions for improvements.
