This is a Redis course that you can learn and use right away!

Covers the topics you need to know to work on projects using Kubernetes.

Become a backend developer who can explain “why it made that decision” about AI-generated code. Across commerce, payments, advertising, and deployment, we’ll turn the design decisions seniors actually made in the field into 8 modules, real fines and outage cases, and hands-on practice with starter code.

Through in-depth theoretical explanations of Kafka Connect and detailed practical training that can be used immediately in the field, we will help you grow into an expert in building data linkage and data pipelines based on Kafka Connect that are needed in the field.

We have gathered Apache Kafka application programming knowledge used in real environments! We will take a look at and practice various functions of Apache Kafka that are key to building data pipelines.

This course is designed to help you learn the use of ksqlDB and its core mechanisms through various hands-on exercises. After completing the course, you will be able to easily and quickly build a real-time streaming data analysis system based on Kafka.

Learn the basic data structures of REDIS and examples of practical use of REDIS through redis-cli (command) practice.

Kotlin mastery via virtual payment server course.

From the core concepts and infrastructure setup of Kafka, Hadoop, Spark, and Airflow to hands-on practice with Java and Python, as well as building production-level pipelines in an AWS environment.

I have created a course titled 'Introduction to Redis/Practical Application (Query Performance Optimization Edition)' that is easy for non-majors to understand and can be applied immediately in practice!
