FAQ
Which Java versions and Spring Boot frameworks do you work with?
I primarily develop with Java 17 and Java 21, using the latest stable versions of Spring Boot 3.x. This ensures your application benefits from modern language features, better performance, and long-term security support.
How do you handle security and sensitive user data in the backend?
Security is a top priority. I implement robust security architectures using Spring Security. This includes setting up secure password hashing (BCrypt), stateless authentication using JWT (JSON Web Tokens) or OAuth2, and configuring proper Cross-Origin Resource Sharing (CORS) policies.
Will you optimize the PostgreSQL database schema for high performance?
Yes, absolutely. I design efficient relational database models with proper primary/foreign keys. I also use Spring Data JPA / Hibernate for mapping, write optimized SQL queries, and implement database indexing to ensure lightning-fast data retrieval as your user base grows.
Do you provide documentation for the API endpoints you build?
Yes. Every backend I deliver includes comprehensive, interactive API documentation using Swagger (OpenAPI UI) or a neatly organized Postman Collection. This allows your frontend team (or you) to test and integrate the endpoints seamlessly without any guesswork.
