About Me

I am a passionate programmer ready to learn new things and improve my current skills. I use Java as my main programming language and mostly work at the back-end part of the development world, but I'm currently learning React and plan to improve my front-end skills to become an experienced full-stack developer.

GitHub Projects

Following projects represents the microservices of a fictional store.
pear-store-fe- front-end part of the application
pear-store-be - core service of the application with basic APIs
account-manager - supporting service for managing user accounts
message-broker - service acting as a messaging bridge between services

Communication between the services are either via REST or Kafka messaging. Following diagram shows, how Kafka message travels through a message broker.
CreateAccountPayload will be sent through a message-broker to account-manager.
If successful, AccountCreated will be sent back, if the username is taken, AccountCreationFailed will be sent.

pear-store-be's Issues

Add errorResponse for createAccount when receiving AccountCreationFailed

Updating db in TransactionSynchronizer not working properly

During message synchronization via TransactionSynchronizer, when updating columns 'REPLY_MESSAGE' and 'REPLY_CLASS_NAME' and then querying the record from db its newly updated columns are still null. However querying only 'REPLY_MESSAGE' and 'REPLY_CLASS_NAME' will return new results.
