VMware Inc.

• Developed microservices using Java Spring Boot for multi-tenant system - usage metering platform that collects, aggregates, and processes the data for VMware cloud and partner services.
• Built cloud infrastructure with Terraform enabling Cloud Governance using Infrastructure as Code Frameworks and deployment of several AWS resources like Athena, Lambda, Glue Crawlers, SNS, and s3, for analytic querying and event-driven computing.
• Designed and implemented an automated process to purchase subscription from Google cloud partner service, reducing manual intervention by Product Managers for customers wishing to purchase subscriptions, reducing clerical errors by 100%

• Performed migration alerts on VMware Aria Operations - Wavefront from AACv1 to AACv2. This is a major step forward in terms of Multi-tenancy support, standardized template for alert definition and so on. This improved overall quality of alerts in terms of features and usability.
• Designed a system for checkpointing of data collections for customer deployed hosts, that also learns to backfill with most recent and accurate usages of the customer with a 15-minute delta. This helped in reducing manual overhead in service, achieved log optimization and usage data accuracy of 97%.
• Created a test plan to determine stability of the metering platform with handling duplicate usages. I also ensured that the system is secured tightly by ensuring that the usage identifier is a deterministic hash of various fields.
• Worked on establishing Role-Based Access Control on VMware CloudGate - service orchestration and authentication tool for the team to achieve Least Privilege and reducing unintended access.

LexisNexis, A Division of RELX Inc.

• Extensive experience in building Software Tools that provide professional solutions for Law Firms
• Created Python scripts to enable communication and data transfer between SQS, Lambda, and EC2 instances
• Experience with supporting continuous integration/continuous delivery pipeline by integrating with Jenkins to deploy projects and check system health and performance

• Sound understanding for Core Java concepts including Multi-threading, Exception Handling, and Collections
• Hands on experience with application architecture to develop Service Oriented models, and Restful APIs, micro services that communicate with NoSQL databases
• Achieved 90% Certification environment stabilization, and improved unweighted availability by 40%
• Developed a multi-threaded solution that collect and compress periodic high-volume data from on-premises data storage, and automated resources from legacy on-premise product during migration, therefore made cost optimizations on the cloud assets
• Wrote AWS Cloud Formation templates to create SQS, and Lambda, which will asynchronously process raw data picked up from data lake repository on AWS EC2 instances

• Designed and developed framework to consume the web services hosted in Amazon EC2 instances
• Developed Multi-threaded solution to retrieve data from S3 buckets, convert the raw data to files that will be utilized by the front-end application rendering documents to customers
• Identified implementation challenges that are effecting product reliability and made significant contributions to addressing these issues by designing, and implementing solutions to these problems
• Developed Junit test cases to rigorously test out resources and improve code coverage
• Extensively worked on improving resiliency and enhance feature cycle time by 25% from every 7.8 weeks to 6 weeks

Engineering Intern

• Programmed several attributes of the 5G messages and implemented concept of scaling using containerized applications
• Accomodate updates to automation scripts to keep up with the changing product architecture with changing customer requirements
• Developed automation tools which will be used during the development of EPC products which supports 5G/4G/3G/2G technologies
• Implemented code that supports the IEs in registration messages using C++ data structures for encoding and decoding of the messages using OSS compiler
