Chitra Vardhini Bellamkonda

• Worked on migrating a monolithic enterprise software to a micro-service architecture. • Designed and implemented a new micro-service from ground up using adapter design pattern. Working with kubernetes auto-scalable clusters, Spring Boot, async messaging over Kafka, MongoDB etc. Able to handle up to 25x more scale. • Designed and maintained a in-memory Redis based Task scheduler. Maintained helm charts for Kubernetes deployments. • Used Lombok notations to remover boiler plate code and test in Cucumber. Worked with Git-CI and ArgoCD. • Wrote a significant chunk of API interaction Azure/AWS APIs via the SDK and contributed to code reviews. Reported SDK issues on the SDK Github and contributed with fixes or drove them to resolution. • Used Azure functions/AWS Lambda for server-less application deployment. Deployed services in EKS/AKS managed containers.

Designed and implemented a DynamoDB-based data versioning system using a number versioning pattern to preserve historical records without overwriting, ensuring full audit ability and data traceability • Optimized read/write performance by leveraging partition key design strategies, avoiding hot partitions, and using conditional writes to maintain version consistency. • Documented and demoed the solution to internal teams, highlighting performance benchmarks and reliability improvements, contributing to potential adoption across other internal services.

• Undertook efforts to implement High Availability using a Nginx reverse proxy to a virtual IP. Reduced downtime by 50 • Upgraded legacy JDK8 enterprise application to JDK11. Managed Maven dependencies for spring and other library upgrades. • Optimized PostgreSQL queries to achieve better performance and query relevant data for feature development. • Wrote multi-threaded business logic for features in a Spring application. Working with dependency injection and Aspect oriented programming concepts. Developed/Updated REST API to support business use-cases. • Monitored Jenkins pipeline for failures and analyzed Jenkins build logs to fix issues. • Analyzed very large log files in a Linux environment using regex patterns and other bash commands to uncover anomalies. • Received recognition for root-causing and fixing multiple complicated scale issues to help get the release out on time. • Provided on-call support for critical customer issues. Came up with bash scripts to automatically recover broken customer environments.

Developed and maintained functional test automation suite using Behavioral Data Driven Frameworks-Cucumber, Cypress, Specflow using tools -selenium web driver for dynamic web applications to achieve reduction of manual regression by 50 • Leveraged the Page Factory Design Pattern to improve test suite maintainability and scalability, reducing code duplication. • Implemented dynamic element handling with Selenium WebDriver and @FindBy annotations, improving test script reliability.
