Project Details:
1. Product Connect:
The PH Integrations team enables data migrations and daily data sync between the Oracle Cloud SAAS platforms to the downstream and upstream applications. To enable this, we had developed Product Connect – A one stop solution that performs data migrations for multiple applications. Product Connect provides a single platform where any system can be on-boarded and the data required for it can be fetched from the SAAS environment and transmitted as a JSON/XML payload.
Technology Used: Java, Hibernate, OJET, SQL, REST Services, SOAP Services
Roles and Responsibilities:
Perform duties of SCRUM Master/ Product Owner for my team.
Develop custom integrations for specific system making use of Product Connect framework.
Handle large quantity data migrations upon environment transitions and upgrades.
Own and maintain individual system integrations.
Develop enhancements for existing systems.
Develop Kubernetes based connector application to serve as pass through between Product Connect and downstream application hosted on Cloud using Oracle Kubernetes Environment.
Architecture planning for re-org and development of PC 3.0.
Integration of Product Replicator and Product Hierarchy Sync into Product Connect.
2. OCI Connect
The OCI Connect is a Micronaut based application hosted on the Oracle Kubernetes Environment (OKE). It makes use of real time data produced by the STOREKEEPER application and pushed to a managed Kafka Stream. The data received is parsed and transformed into logical entities and stored in in Oracle DB. These entities are then validated, transformed and synced to the OCI Fusion Cloud as entities representing the Data Centers created. This application plays a pivotal role in managing existing Data Centers and also in the setup of new DCs as the source of truth.
Technology Used: Java 21, Kubernetes, Kafka, Java 8, JPA, Rest Services
Roles and Responsibilities:
Build the OKE Micronaut Application from scratch
Connect to Streaming service using Streaming SDKs
Developed application logic to handle data and transformation logic.
Developed Rest Service endpoints for the application.
3. Site Setup Automation for Data Centre Buildings:
The site synchronization project was java based application which enabled the setup of data center buildings in Oracle Fusion Cloud Inventory Platform. The application serves as a orchestrator between various systems like CDM, HCM, Hawkeye and Fusion. This application enabled the automation of the site setup process reducing the turnaround time from 10+ days to effectively less than 24 hours.
Technology Used: Java 8, Kafka, JPA, Rest Services
Roles and Responsibilities:
Developed the architecture from ground up.
Served as Project POC.
Developed application logic to handle data and transformation logic.
Developed Rest Service endpoints for the application.
Successfully enabled delivery within very strict guidelines.
4. Product Validator:
Product Validator application facilitates daily routine check on criteria of all items available in the SAAS Cloud Portfolio and flag any item which falls out of criteria. The application works on a cadence of once every 12 hours and flags items based on specific rules used to validate them. Any item which falls as an outcome of these rules are flagged and notified to the respective teams. The application also has a UI which enables users to login and view the items reported as errors under various rules, teams and groups.
Technology Used: Java, Hibernate, OJET, SQL, REST Services
Roles and Responsibilities:
Build SQL based queries (rules) to be run on a daily basis to detect items that do not match criteria.
Develop UI enhancements.
Generate and publish weekly reports containing insights for business to review erroneous items.
5. Product Hierarchy Sync:
The Product Hierarchy Sync application is used to sync data from the DRM System to the Hierarchy of categories in the Fusion SAAS domain. The application fetches data from the DRM PAAS REST Services and based on certain validations, synchronizes the delta changes to the categories in Fusion using the SAAS SOAP Services. The application also creates items for leaf level categories.
Technology Used: Java, Hibernate, OJET, SQL, REST Services, SOAP Services
Roles and Responsibilities:
Own and maintain the application and enhancements.
Monitor daily jobs and resync any failures.
Run monthly health checks and perform monthly resync jobs.
Server as liaison between development team and business teams.
6. Inventory Automation:
The Inventory Management team handles the supply and warehousing of parts which are used by business. These part details are stored in the Oracle Cloud SAAS platform. The SAAS environment provides ability to store, maintain, transfer, return, generate receipts, record shipments, generate reports and many other functionalities. Upon every Cloud environment upgrade, it is essential to perform regression on all these functionalities. Hence Selenium automation flows were developed to be run after every environment upgrade.
Roles and Responsibilities:
Conceive and Develop automation flows for every process.
Maintain and Execute flows after every upgrade.
Integrate Inventory flows with other flows like Product Hub for end-to-end testing.
Sole developer of code base from scratch.
