I finally finalized, although “finalized” is probably not the right word, since this is a project that will continue to grow, my own CRM/ERP system that supports the organization of my work.

The project is built with Next.js and Tailwind and uses a MySQL database. It is a multi-user system featuring client management, invoicing, revenue tracking, an integrated email client, and an online lead research system powered by a small data-scraping engine (Google Reviews, LinkedIn, etc.) that returns a score indicating whether a business could be worth contacting to offer services.
