Milestone Four focused on showcasing my proficiency in databases through the Grazioso Salvare project a web-based animal rescue dashboard developed with Python, Dash, and MongoDB. The artifact demonstrates advanced skills in creating interactive dashboards, integrating external databases, and building secure CRUD operations with user authentication. It also highlights my ability to manage separate read-only and admin views, dynamically transition between layouts, and handle complex callback interactions. This milestone marks my progress in designing scalable, data-driven applications that deliver tangible value in the real world.
