▪ Worked as part of a big team that migrated our operations to Cloud as well as technology platform upgrade.
▪ Planned, executed and led from QA side from project initiation to production release.

ASDA Groceries Website was redesigned and made Responsive to devices.

Improved Favorites:

In our ASDA Groceries site, the buyer will be able to 'favorite' the products in few ways. Two commonly possible ways are 1) Customer explicitly favourite'ize the products 2) By a system's logic based on Customer's past orders.

This project involved changes & improving the existing features in Backend, Front-end(Responsive Web) and Business logic(API) layers to implement the 2nd way of favourite'izing the products and I worked in testing and certifying the… Show more

Architected a Real-Time Analytics system using:
Apache Flume – For events streaming
Apache Kafka – For persisting
ElasticSearch – Indexing
Kibana – For visualization

Early adoption of the feature is required to evaluate & determine feature success.

Product Tour that helps the customers understand the product in a simplified fashion.

Hopscotch is a framework to make it easy for developers to add product tours to their pages. Hopscotch accepts a tour JSON object as input and provides an API for the developer to control rendering the tour display and managing the tour progress.

To learn more about Hopscotch and the API, check out linkedin.github.io/hopscotch.

About:
--------
☛ Kafka Standalone Consumer will read the messages from Kafka, processes and index them in ElasticSearch.

☛ Easily Scaleable & Extendable !

Inception:
-----------
☛ We had a need to Subscribe messages from Kafka process the messages to a desired format and Index it in ElasticSearch. There was a Kafka ElasticSearch River available, but it doesn't solve the problem of "need to read from multiple topics | partitions and index across multiple ElasticSearch Index/Instance".

☛ Hence started coding this project, completed and have published it in GitHub.

☛ This Consumer will help complete an *EcoSystem* that consists of using "Apache Kafka" for "Publish & Subscribe" & "ElasticSearch" as "Search & Analytics" Engine.

☛ Please try it out and reach out to me for feedback. Also, please help build it further if interested.

✔ Please see the detailed presentation above for descriptive details !!

This brought me a good understanding of ElasticSearch and also a good understanding of a *Ecosystem* around processing tools.
