• Data Structures & Algorithms (DSA): Ability to teach and evaluate fundamental and advanced DSA concepts using Java, often including interview-style problem-solving (e.g., Leet Code/ Hacker Rank equivalent problems).
• Testing: Expertise in Unit Testing (JUnit 5, Mockito), Integration Testing, and Behavior-Driven Development (BDD) using tools like Cucumber.

II. Enterprise Frameworks & Architecture (Mandatory)

• Spring/Spring Boot: Expert knowledge of the entire Spring ecosystem, including Spring Boot 3.x for rapid application development.
• Spring Core: IoC, AOP, Bean Lifecycle.
• Spring Data JPA/Hibernate: Advanced ORM concepts, criteria queries, performance tuning, and transaction management ($@Transactional$).

IV. Database & Frontend Exposure

• Database: Advanced SQL (joins, stored procedures, indexing), and experience with NoSQL databases (e.g., MongoDB, Cassandra, Redis).
• Frontend (Full-Stack Trainer only): Working knowledge of modern JavaScript frameworks (React or Angular) to facilitate training on full-stack integration and REST API consumption.

Training Delivery Expectations

• Curriculum Management: Ability to manage content on a Learning Management System (LMS) and a Version Control System (Git/GitHub/GitLab).
• Hands-on Labs: Design complex, real-world lab environments (often requiring cloud/Docker/K8s setup) and troubleshoot live coding issues for 15+ trainees simultaneously.
