MetLife, TX July 2024 - Present

Software Engineer.

Built and maintained ASP.NET Core microservices and REST APIs using Entity Framework Core with LINQ for data access, covering end-to-end claims intake, validation, adjudication, and settlement, ensuring reliability and scalability across high-volume systems.

Developed UI components and internal dashboards with React, TypeScript, RxJS, and PrimeReact, integrating centralized state, role- based access, and advanced filtering, bulk actions, and responsive experiences on both desktop and mobile devices.

Managed Azure DevOps YAML pipelines and Git repositories using GitFlow, automating build, test, image scanning, and multi- environment deployments to AWS EKS clusters while enforcing pull-request reviews, branch policies, and release notes.

Optimized SQL Server stored procedures, partitions, and indexes, shrinking average claim search latency from 3.5s to 1.8s and cutting end-of-day ETL duration by 45 minutes, which reduced after hours batch failures and freed analyst time.

Implemented AutoMapper profiles and FluentValidation rules across 20 services, removing roughly 6,000 lines of repetitive mapping code and lowering production defects tied to bad payloads from 18 to 5 per release cycle.

Leveraged AWS S3 to store 10 TB of claim documents and MongoDB for high-throughput metadata access, set up CloudWatch alarms and dashboards, configured ElasticSearch (OpenSearch 1.x) delivering policy searhces in under 600 ms across 12 million indexed records.

Introduced Redis caching plus RabbitMQ and AWS SQS queues to decouple document generation and notifications, boosting peak-hour API throughput from 850 to 1,150 requests per second and keeping latency below 250 ms in quarterly load tests. Zensar Technologies, India May 2020 – November 2022 Software Engineer.

Developed RESTful C# ASP.NET Web API endpoints on .NET Framework with OpenAPI documentation, JWT auth, AutoMapper, and Dapper. Built Angular components to consume these APIs, handling ~8000 daily financial transactions with avg response time of 180 ms.

Implemented Entity Framework Code-First migrations alongside Dapper for micro-ORM data access; configured SqlConnection pooling, leveraged SqlBulkCopy for high-volume inserts, and used SQL Server Profiler and Query Store to eliminate query bottlenecks.

Optimized Amazon RDS SQL Server schemas and T-SQL stored procedures; tuned queries with Query Store and DMVs, adjusted RDS parameter groups, and monitored with Performance Insights to reduce the end-of-day batch processing window by 4 .

Deployed APIs on AWS EC2 behind ALB using Git-based pipelines and CloudWatch for monitoring API performance, and managed sensitive credentials securely in AWS Secrets Manager.

Built containerised ASP.NET Core microservices with REST APIs for HIPAA 278 prior-authorization request processing, and Swagger for API documentation, enabled to handle 5,000 authorizations per day with full regulatory compliance and minimal production issues

Implemented MassTransit messaging for inter-service communication, integrating with RabbitMQ to manage 1.3M+ messages annually.

Managed transactional data in Azure SQL Database with table partitioning, indexed views, and T-SQL stored procedures, reducing query latency by 30%; and stored EDI audit logs in Cosmos DB with TTL policies, cutting log retrieval times by 200 ms.

Collaborated on Azure DevOps (Git) pipelines and Helm-based deployments to Azure Kubernetes Service (AKS), integrating Azure Key Vault for secure secrets management and enabling 20 zero-downtime releases per quarter.

Developed xUnit/Moq unit and integration tests, achieving 78% code coverage and cutting reopened QA defects by 50 %. Skills
