Experience

nov, 2020 – present

full stack java developer, IBM,Halifax

ABout:

●The End Client is Bestbuy and this project aims at integrating the order flow with several warehouse vendors.

●We have designed API’s and deployed in AWS. This API’ would validate the request which we receive from Message Bus and do a transformation with respect to the vendor.

●Every endpoint has got its own threshold configured keeping the vendor API’s rate limit in mind.

●And an efficient retry mechanism was put in place, just in case we receive 5XX errors or timeouts we add the records to another queue.

●This queue in hooked to a Lambda and it’s scheduled. So all the missed records would be retried again and If it again fails after configured retry attempts, it would be pushed to a Dead Letter Queue.

Responsibilities:

jun. 2017 – oct 2018

JAVA DEVELOPER, accenture,ON

About Project:

I was a part of R&D Team at Accenture and I got an opportunity to work on the latest technologies present.

One of the prototypes, I have worked on is navigating the app to a specific page based on voice command.

Imagine a Bank application where it has a lot of menus and activities. It’s a challenge for a consumer to navigate from one page to another as it involves a lot of browsing.

In order to improve the accessibility, we have developed a voice-based navigation system.

If the user says Add Beneficiary, we would directly navigate him to that activity and open that form.

Responsibilities:

To continuously learn and keep an eye on the latest emerging technologies.

To convince people on the tech stack we propose, which means to do a detailed analysis on the tech stack and propose pros, cons, licence and pricing.

To analyze NLP’s available in the market and to check which NLP would suite for the use case.

Tried AWS LEX, Google Dialogflow and RASA and proposed the pros and cons of individual NLP Engines.

Developed Spring Boot wrapper layer and this would return the activity ID depending on the user input.

Perform peer code reviews and did a performance comparison on an application written in Node Js + Express and Java + Spring Boot.

Tech Stack: Java, Java Beans, Node JS, J2EE, REST, SOAP, Spring Boot, Angular JS, Google Functions and Dialog flow, AWS LEX, AWS API Gateway, AWS Lambda, Dynamo DB, AWS Comprehend.
