     helped me get this job Using Docker and Kubernetes to transform a monolithic application into a microservice architecture: 1) To do this, a monolithic (single, huge application) must be converted into a microservices architecture. 2) In order to facilitate this shift, solutions like Docker and Kubernetes are used. The outcome of this change is: 1)Modularity and flexibility are increased during the application's development and maintenance processes. 2)Updating and maintaining individual microservices is simpler than doing so for a monolithic application. 3)Server Cost: There is a 20% reduction in the cost of hosting and maintaining the application. Using Jenkins, create a build pipeline: The application is currently built and deployed manually as part of the manual deployment procedure. An automated build pipeline is being implemented using Jenkins, a well-known automation tool. Before Jenkins, building and deploying required about eight hours. Following the installation of Jenkins, the procedure now completes in just one hour. Designing a Compliance Strategy for GDPR: Compliance with the General Data Protection Regulation (GDPR) is necessary in order to handle sensitive user data. A security risk with the existing system is that it saves some user-sensitive data in plaintext. This project entails developing and implementing a GDPR compliance solution, probably requiring encryption or other data protection techniques. Making an API for REST Services' Backward Compatibility: Versions (1.4, 1.2, and 1.1) of the REST API that is currently available have been specified for various clients. Clients have to adjust to changes in API versions, which might be a problem. The project entails developing a new API that guarantees backward compatibility. This modification creates a single API that maintains consistency across version changes. When the API is updated, clients don't have to change their user interfaces, making the transition easier.

     Creating a Spark Job for Data Masking on Hive Warehouse Data: A Spark job has been developed to perform data masking based on a configuration for selected Primary Key columns on data stored in the Hive warehouse. PayPal is dealing with a massive 10 Petabytes of big data stored in a Hive cluster with an older Hive version (1.1) that doesn't support certain updates. To address this, a PySpark job has been created. This PySpark job identifies GDPR (General Data Protection Regulation) user data in tables and applies masking to sensitive information. The Spark process is capable of handling 2 million records in just 30 minutes, indicating its efficiency in processing large datasets. Creating a Data Pipeline Using Spark, Hive, and Kafka: A data pipeline has been designed and implemented to fulfill specific client requirements. The technologies used in this pipeline include Spark, Hive, and Kafka. Data flows through this pipeline, likely undergoing various transformations and processing steps as needed by the client. Developing a Standalone Java Application for Kafka Data Processing: A standalone Java application has been created to listen to a Kafka topic. When XML data is received on this topic, the Java application processes the XML, extracts data from it, and stores it in Hive tables. This application effectively acts as a Kafka consumer, processing data in batches, with each batch containing 50,000 records. Creating a REST Service Using Spring and Java for PayPal Honey Entity: A RESTful web service has been developed using the Spring framework and Java. This service is specifically designed for the PayPal Honey Entity, which likely represents a component or module within the larger PayPal system. The REST service provides an interface for interacting with the Honey Entity, enabling external systems or clients to access its functionality.
