WordPress to HTML/CSS/JS/Node.js Conversion

I need my WordPress site converted to HTML/CSS/JS/Node for easier maintenance since I am Node.js developer. The site should retain its current design and layout, and maintain full backend and frontend functions without CMS.

Website is www.domacepalacinke.rs

Key Requirements:
- Full replication of current site design and layout
- Comprehensive knowledge of HTML/CSS/JS/Node/Express
- Ability to replicate full backend and frontend functions
- No need for CMS in the new site

Technologies that I want to be used are:
- Node.js, Express, EJS for templates
- MySql database and Sequelize for data
- Pure HTML/CSS/JS frontend
