Java back-end development

$10/hr Starting at $50

  1. Java Fundamentals: Solid understanding of Java programming, including proficiency in object-oriented programming (OOP) and concurrent programming.

  2. Distributed Systems Theory: Knowledge of the principles, concepts, and design patterns of distributed systems. Familiarity with concepts like CAP theorem, consistent hashing, and distributed transactions.

  3. Microservices Architecture: In-depth understanding of microservices architecture, covering aspects such as service decomposition, API design, service registration and discovery, and containerization.

  4. Spring and Spring Boot: Mastery of the Spring framework and Spring Boot for simplifying development, implementing dependency injection, handling transactions, and building RESTful APIs.

  5. Distributed Storage: Familiarity with distributed storage systems such as Redis, MongoDB, Cassandra, understanding their features, usage, and performance optimization.

  6. Message Queues: Experience with message middleware concepts and usage, e.g., Apache Kafka, RabbitMQ, for achieving asynchronous communication and decoupling system components.
