Portfolio - CoinAlertNews (React/NextJS, built admin panel, dashboards, performance optimization)

Description

Hi, I’m Kamil, and on this project, CoinAlertNews, I handled the frontend architecture and development. I first built the platform in React, then later rewrote the frontend with native Web Components to improve performance and make the architecture lighter. After that, article pages reached 99 out of 100 in Lighthouse. I also built the admin panel, integrated it with the REST API, and worked on performance optimization across the product. As a result, the overall web app became around 40% faster. This project reflects how I work as an engineer: I focus not only on building interfaces, but also on improving architecture, performance, and scalability.
