Website History
This website originally began as a project developed using Vue.js, a simple and flexible progressive JavaScript framework. Interestingly, I initially chose Vue thinking it was the same as ReactJS, due to some early confusion during my learning phase. What started as an accidental introduction to Vue quickly became a productive learning experience.
Later, to deepen my understanding of ReactJS, which was my actual target all along, I decided to rebuild the project using Next.js, a powerful React-based framework. This migration helped me explore modern web development concepts such as server-side rendering (SSR), dynamic routing, API routes, and React component-based architecture.
The current version reflects this journey: combining practical experience in both Vue and React ecosystems, while pushing me further toward full-stack proficiency with a more production-ready setup.
