Spring Service Lab
A production-minded Spring Boot service used to practice API design, persistence, caching, security, and operational boundaries.
Project overview
Spring Service Lab is a focused environment for turning backend concepts into working code and measurable behavior.
Background and problem
Interview knowledge becomes more useful when it is connected to implementation decisions. This project creates that bridge for validation, transactions, indexes, caching, and security.
Technical solution
The service uses layered boundaries, validated REST contracts, JPA persistence, MySQL, and Redis. Docker Compose keeps local dependencies repeatable.
Results
The project provides reusable examples that can become deeper Blog posts and future interactive demos.
