I've worked on a variety of projects, from simple websites to complex web applications. Here are a few of my projects.

Bitcoin Price Extension

Implemented a Node.js backend with Redis caching to minimize external API requests and significantly improve response performance. The entire system was containerized with Docker for seamless deployment and reproducibility.
