Worked in the Lumin team enhancing the service layer for Accounts API (Post, Get, Patch, Delete) for capitalgroup.com using Java 1.8, Spring Boot, Oracle, Hibernate ORM, Junit, Mockito, SonarQube, Kafka.

Worked on re-platform the SOA Accounts API from older V1 to V2 to support Asynchronous & Synchronous accounts creation.

Write JUnits using Mockito, Power Mockito and ensure code coverage is above 80%.

Setup CI to perform static code analysis and report code health and metrics using Sonar.

Worked on UI related bug fixes using Javascript framework React JS & Jquery.

Worked on VAC (Validate Account Creation) API which involved working with asynchronous event driven communication using Kafka.

Enhancement of the existing functionality to persist the messages to Cassandra DB in Kafka.

Complete Unit test and functional test coverage for all bug fixes and overall features hooked it to CI through Jenkins.

Documented all Low-level, activity, object modelling design diagrams for flows worked on.

Shared responsibility in development of Pricing tool to compare all the prices of each product between Apple Online Store (AOS), Apple Store App (ASA) and Wechat using Javascript ES6, NodeJS, Express JS, Mongo DB, Mongoose, Redis.

Shared responsibility to design, develop and deploy Orders API (Create/Post Order & Get Order) in microservices architecture using Spring Boot, Java 8, Hibernate, SQL, Kafka

Shared responsibility in adding an orchestration layer for Orders API as (ordersplatserv) microsevice which communicates synchronously and asynchronously to various downstream services.

Shared responsibility to enhance performance for Orders creation by redesigning the ordersbuyerplatserv api and making sure certain calls are being communicated asynchronously. API response time has reduced due to this and SLA was met.

Worked in highly scalable micro services architecture with highly business critical services utilizing distributed storage such as Cassandra

Developed back end Automation framework in Java which supports ASA’s multiple tenants using TestNG, SQL, REST, Maven, POM, JSON technologies and work on enhancing the current framework for testing the developed code to ensure the software quality.

Responsible for functional testing of Orders API, preAuth API and Retail API and E2E signoff’s.

Responsible for enhancing the reporting module of ASA (Test automation Framework) by integrating with TestNG, Maven plugins.

Responsible for Monitoring and Analyzing Splunk logs.

Enhancement of the DEEP libraries with new mechanisms like Event engine and Event audit.

Implementing the new message retry mechanism using kafka in the event of any failure in the downstream systems.

Rest services templates are generated using swagger specifications

Development of new listeners for producers and consumers for both Rabbitmq and Kafka.

New library development with micro services architecture using Rest APIs, spring boot and pivotal cloud foundry.

Enhancement of the existing functionality to persist the messages to Cassandra DB in Kafka

Implementation of Hystrix circuit breaker to avoid loss of messages during handling of messages at the consumer level.

Implementation of Zuul proxy as the API gateway

Test plans and Unit Testing using Junit and Mockito.
