Optimised APIs by refactoring inefficient API logic and implemented Caching strategy(Redis) to reduce the latency of an application by around 30 percent. Improved the customer search logic to display the closest matching results using Elasticsearch.

Defined a contract, developed and exposed an API used by microservices to save the question-level scores, and maintain consistency in candidates data. Implemented a distributed locking mechanism using Aerospike to ensure safe concurrent updates to a candidates test details. Designed and implemented the Low Level Design of Central Scoring System, adhering to coding standards, design patterns; acting as SPOC and collaborated with cross-functional teams for the smooth delivery of the product. Revamped the Devops Simulation architecture to significantly reduce latency, decreasing the initial assessment start time from nearly 2 minutes to just 30 seconds. Synchronized AWS CloudWatch to capture and retrieve all commands entered by a candidate in the terminal. Implementated IAM Role for the launch and termination of EC2 Instances to manage access control, enhancing security, and simplifying permission management.

Worked on building the complete logic of Process Monitoring Scoring, a Game based assessment, from scratch. Took charge of product leadership through its development. Built an automated and configurable scoring utilising the Factory design pattern and wrote unit test cases to evaluate a candidates understanding of full stack assessments. Enhanced the architecture of Writex Scoring by rewriting the legacy code, resulting in a significant reduction of scoring time from 2 mins to around 1 min. Built a docker image of spring boot with Theia IDE, augmented with various extensions of VS Code to give a simulated environment.

Collaborated and worked on an internal HPE tool to check whether all the nodes of the communication network function properly or not.
