Desired candidate profile

1. Core Java Expertise

• Java SE (Standard Edition): In-depth knowledge of core Java features, including object-oriented programming (OOP), Java collections, exception handling, and Java APIs.
• Concurrency and Multithreading: Expertise in Java concurrency, thread management, synchronization, and parallel programming to build scalable applications.
• Java Memory Management: Understanding the Java garbage collection mechanism, memory leaks, and optimization techniques to ensure efficient memory use.
• Java 8+ Features: Familiarity with modern Java features such as lambdas, streams, default methods, Optional, and the new Date/Time API.

2. Software Architecture

• Design Patterns: Deep understanding of common design patterns such as Singleton, Factory, Observer, Decorator, Strategy, and Adapter to create reusable, maintainable, and scalable software.
• Microservices Architecture: Expertise in designing and implementing microservices-based applications using tools like Spring Boot, Spring Cloud, or Quarkus for building modular, independently deployable services.
• Monolithic vs. Microservices: Ability to decide when to use monolithic architecture or microservices based on business and technical requirements, and understanding the trade-offs involved.
• Service-Oriented Architecture (SOA): Knowledge of service-oriented principles, with a focus on designing loosely-coupled and reusable services that communicate via well-defined interfaces.
• Event-Driven Architecture: Experience designing systems using asynchronous communication patterns, with event-driven architectures leveraging tools like Kafka, RabbitMQ, or ActiveMQ.

3. Frameworks and Technologies
