Senior Integration Consultant

Few of the Azure log analytics database tables i.e. Perf & KubeInventory table generate CPU usage logs which are required to measure one of the key performance indexes i.e. core used across an organisation. Unfortunately due to heavy logging and costs maintaining this log for a long duration was a challenge. This project was packed with an analysis of Azure services supporting data export, data ingestion & data visualisation use cases. As a solution following pattern was used 
Data export: A scheduled logic app flow was written to query and stage results in a blob container
Data ingestion: Azure event hub was configured on the storage account to sync data in one of the Azure data explorer custom database table
Data visualisation: ADX UI dashboard was implemented on custom table data to showcase real-time compute usage data
This solution is being used to ensure customer is complaint against current compute subscription.

 Compute log retention solution using Azure data explorer

A dynamic object-store implementation using Azure Redis SDK and Spring. The project enables customers to stage data over distributed Redis cache and achieve high availability, resiliency, durability, performance & low latency. The implementation also offers an invalidation service where a key or whole cache can be invalidated which is one of the key USP of this product.

Distributed Redis cache module

A one-stop solution for API developer's to start their development, this tool was developed using the Maven archetype and ties all the engineering best practices together i.e. naming pattern, project structure, test framework, maven dependencies, logging, exception handling and a sample API contract and it's implementation. Saved 30% of the development effort and brought uniformity across all the APIs developed post it's release.

 Starterkit for developer

An alternative to enterprise batch processing product, this product was written on Java & Spring batch modules. Consumes any collection stream and process chunks in parallel backed by a monitoring dashboard. Developed as an eclipse update site project, which can be imported and used as a plugin.
