About

Hi, I am Kai Wern.

Welcome to my blog. Here I write about software and life. Some of the tools I used day to day are: vim, Elixir/Phoenix, Rust and PostgreSQL. You can expect posts about these from my blog.

I’m now into photography and drawing as well and am trying to write more consistently.

Now

Currently, I am attending RC. During my time here, I’ll be focusing on:

• Writing simple database in Rust, inspired by Let’s Build a Simple Database tutorial.
• Writing a book about building a simple database in Rust, based on my work above and inspired by Let’s Build a Simple Database and Crafting Intepreters.
• Learning more about database and exploring other lower level system like networking, observability and etc.
• Publish and share more of my work publicly.

Abandoned Projects

These are some of the side projects that I worked on in the past to learn, which now has been abandoned by me:

• TIL: A Today I learned web application developed with Phoenix. It includes basic features like adding post with Markdown and tagging. The idea of the application is inspired by Hashrocket TIL.
• Expendere: A personal finance management web application which includes features like expense tracking, budget and recurring transaction (bills). It is developed with Ruby on Rails and a little bit of Preact. Due to limited time (and interest) available, it is abandoned now.
• hbtrack: My first first CLI to track habits! It’s written in Ruby and still function well. But I stopped using it and use Streaks instead.
