kyungyeon.dev is a personal technical blog run by Korean developer Eric. It uses Notion CMS as its content backend, automatically building into a static site for public access after articles are written and published. The blog focuses on sharing hands-on experience in back-end development, database architecture, tech stack migration, cloud infrastructure and other related fields. It has published over 100 technical articles to date, with content centered on real-world problems encountered in production environments and their corresponding solutions.
The blog's content leans toward in-depth practical experience, not introductory basics. Most posts are summaries of lessons the author learned and solutions developed after working through real project challenges: for example, the full migration process from NestJS to Spring Boot, the migration plan for Shopify's inventory system from Redis to MySQL, a breakdown of the real operational risks of MySQL DDL locks, and a business-oriented comparison between layered architecture and hexagonal architecture. It also shares practical approaches to implementing AI-assisted development. The content is extremely dense with actionable insights, every solution comes with complete implementation steps and the author's underlying reasoning, making it highly valuable for reference.
The site is directly accessible in China's network environment, with stable loading speed, a clean layout and no ads. The downside is that all content is in Korean with no Chinese version, which creates a certain language barrier for domestic readers.
This blog is an excellent read for experienced back-end developers and architects, especially developers currently working on tech stack migration or database architecture optimization. You can avoid many common pitfalls by learning from the author's hands-on experience, and reference his fully tested complete migration and validation processes.
