• Currently working on an asset management project for Hitachi Energy system where a user can add failure Modes for an asset, can predict potential failure modes using potential failure mode data and real time data received from sensors, can export/import the same data via excel.
• Used Agile Development Methodology of software development Developed Cross cutting concerns like logging Utility classes, Kafka Consumers, Document storage templates (Connectivity to Azure Blob storage service), and Outbox. Created Kafka Consumers to consume the data on to a topic that helped to have a data sync between two different language based microservice.
• Developed GRPC Controller classes to have communication between multiple microservices, which internally made the classes faster with low latency and using protobuf for data exchange between the services.
• Developed Kafka Producers to publish data to a topic to have an asynchronous way of handling data which helped the import functionality to process the data from excel file in the background and not allowing the user to wait for a longer time.
• Implemented Circuit Breaker and Retry patterns of Resilience4j framework that helped microservices to be fault tolerant and provide a fallback methods to handle services that are throwing exceptions.
• Backend microservices are implemented in CQRS pattern that helped us to separate out the read and write operations allowing users to read the data from Elasticsearch and write the data to a PostgreSQL database . This helped the end-user not to be blocked to read the data when the service that is writing the data to PostgreSQL is down.

• Identify, prioritize and execute tasks in the software development life cycle.
• Develop tools and applications by producing clean, efficient code
• Designing and implementations of restful Web services
• Involved and implementing in the business logic and coding of DAO classes during spring
• Maintaining the project and resolve the user raised issues
