About

Hello, folks! I'm Trong Khanh (aka Karhdo)

I have a passion for JavaScript/TypeScript and website development. I work mainly software engineer at Spartan, deeply engaged in the Dealops project, with JavaScript, TypeScript, NodeJS, ReactJS, and Monorepo.

Why have this blog?

My desire to practice my skills and share my acquired knowledge fuels my endeavors.

I founded this blog as a means to document and share the knowledge and practical wisdom I've acquired during my journey as a software engineer.

Writing and taking notes helps me solidify my understanding of new concepts and technologies. I hope my blog can be a useful resource for fellow web developers.

I would greatly appreciate your thoughts and comments on what I have written .

Tech stack

This blog is built with Next.js and Tailwind CSS using Tailwind Nextjs Starter Blog.

This blog site takes inspiration from leohuynh.dev. I appreciate Leo Huynh and Timothy Lin for their contribution to this minimal, lightweight, and highly customizable blog starter.

A few major over-engineering-changes from the original repo:

• Upgrading to React 19, Next 16.
• Adopting Typescript, committing with Conventional Commits
• Monitoring site with Umami website analytics
• Theming in dark mode with Tokyonight Neovim Theme colors for better contrast.
• My website refers to the design and code from the lehuynh.dev repository and incorporates the tailwind-nextjs-starter-blog template, version 2.0.
• Bumping up mdx-bundler, rehype/remark plugins and dependencies to the latest version
