Project description:
"I need a concise Spring Boot application that wraps a Spring Batch job so it can run as a Lambda-style, on-demand function. The job must connect to a relational data source—specifically PostgreSQL—read the data in chunks, apply custom processing, and write the results back.

Code requirements
• Java 21 with Spring Boot , Spring Batch, and the appropriate Lambda runtime adapter
• Clear separation of reader, processor, and writer classes
• Robust error handling and SLF4J/Logback logging
• JUnit 5 tests covering the processing logic

What I will hand over
• Existing PostgreSQL schema and sample data
• Access credentials and expected result set for verification

Deliverables
1. Git repository with all source code and a descriptive README
2. Maven build that produces a deployable artifact
3. Instructions to configure environment variables for database connectivity and to trigger a test run
4. SQL migration scripts if additional tables or indexes are required
