I’m kicking off a brand-new web application and want the entire stack set up from scratch. The backend must be built with Spring Boot, exposing clean REST endpoints and following best practices for security, logging, and testing. Data will live in a relational store—MySQL or PostgreSQL—so the schema, migrations, and repository layer should be wired for one of those engines with minimal friction to switch between them. On the front end I’m open to modern JavaScript frameworks; feel free to propose React, Angular, or another popular choice as long as it integrates smoothly with the Spring Boot API and supports responsive design. Because this is green-field work, the project will move through typical milestones: design, MVP, iterative feature drops, and deploy...
