Hey, I'm Kyohei! 👋

Kyohei Fukuda - Software Engineer

About

I'm a JavaScript Developer with 6+ years of experience in web systems development.

  • Expertise: TypeScript, Node.js, React, Serverless, Technical SEO.
  • Love: Open Source Software, Indie Hackers community

Interests

I love to work on the UI side and improve the end-UX experience of a service. For example, shortening the time for users to reach their goals through the app is always one of the objectives I keep in mind during the development process.

  • I like to simplify the complex stuff and make it approachable to many people.
  • To achieve that, I have researched declarative programming and object-oriented UI design.

Articles

This article will introduce you to a collection of libraries for creating PDFs in Javascript, showing their use-cases and comparing their features. In particular, I focus on the following aspects:

  • Is it easy to integrate with a modern front-end application?
  • Does it work in Node or the browser?
  • Is it available as a UMD module?
  • Is it a Typed library?
  • Does it support custom fonts?

I suggested using Github to manage a personal task, which is already familiar to engineers, and using it for projects other than system development. It can be used as a free and convenient project management tool.
For example:

  • You can create a project called "house moving," create an Issue of things to do, write down the procedures and other details, and manage them in the Kanban section.
  • Set up an "Issue" of the book to read, and then once you read it, you can leave a comment on your "Issue" notes.
