Technical articles on Spring Boot, JWT, REST API design, and backend engineering.
These are planned articles I'm writing based on real backend problems I've encountered. Publishing schedule: ~1 article every 2 weeks.

Move past CRUD. Proper resource naming, HTTP semantics, idempotency, pagination, error response schemas, and versioning strategies for production APIs.
JPQL vs native queries, derived method names, projections for selective data fetching, and N+1 problem diagnosis and solutions with Hibernate.
Implementing RBAC with Spring Security from scratch — UserDetailsService, GrantedAuthority, method-level security with @PreAuthorize, and securing REST endpoints.
Normalization to 3NF, foreign key strategies, index design, and how your database schema decisions directly impact your JPA entity modeling and query performance.
