Project History
Analytic App for the Automobile Industry
A multiprogramming-based app for analyzing and providing ratings based on car driver behavior. Based on the ratings, insurance is provided to the users.
I was the back-end developer and handled all the DevOps work. I was getting data from each automobile using IOTA devices. With the help of Kafka and other tools, we stored that in the data lake, after which the lambda function was triggered, and it parsed that data in different reporting formats and was stored in the structure database. From that report, we rate the user's experience.

Privilege Access Management (PAM)
https://arconnet.com/Privilege Access Management (PAM) is a highly effective solution that helps manage, control, and monitor privileged user activities. The solution provides the IT security team with a centralized policy framework to authorize privileges based on role and responsibilities and offers rule-based restricted access to privileged accounts. Privileged users are super admins who have elevated permission to access critical information.
I used OpenCV, Emgu CV, Automation Anywhere, a Java access bridge, and UiPath. I also used different DevOps tools like Jenkins, Puppet, Bamboo, AWS CodePipeline, Kubernetes, and Amazon EKS.
