Harsha Vardhan

-> Architected and delivered high-throughput .NET 8 backend systems and ASP.NET Core Web APIs for enterprise healthcare platforms, engineering HIPAA-compliant microservices handling real-time claims adjudication, EHR/EMR data orchestration, and provider workflow automation deploying containerized services through Amazon EKS and Docker, orchestrating event-driven pipelines using Amazon SQS, SNS, Kafka, and AWS Step Functions, and managing transactional and analytical data across Amazon RDS, PostgreSQL, and Redshift for scalable backend processing. -> Owned backend security, resilience, and clinical data governance by implementing OAuth2/JWT authentication integrated with AWS IAM and Secrets Manager, enforcing PHI protection aligned with OWASP and HIPAA controls, engineering fault-tolerant microservice communication patterns using Polly retry policies and distributed caching with Redis, instrumenting end-to-end observability through Application Insights, Grafana, and Serilog, and automating infrastructure provisioning with Terraform and AWS CloudFormation to ensure repeatable, production-grade deployments. -> Integrated AI/ML capabilities into the .NET backend pipeline by building RESTful inference endpoints that consumed Azure Cognitive Services and OpenAI APIs for intelligent document processing, clinical risk scoring, and predictive analytics engineering feature extraction services, model-serving middleware, and automated anomaly detection workflows within the microservices architecture to deliver AI-augmented decision support and operational intelligence across healthcare data platforms.

-> Built and modernized enterprise banking applications across the full SDLC using .NET 8.0, ASP.NET Core, and React, engineering high-performance microservices for transaction processing, distributed workflows, and secure API ecosystems while applying Domain-Driven Design, CQRS, and event-driven architecture principles deployed on AWS EC2 and managed through AWS IAM. -> Designed and managed cloud-native infrastructure on AWS, deploying containerized services through Amazon EKS and Docker, building CI/CD pipelines with Jenkins and AWS CodePipeline and CodeDeploy, implementing scalable messaging with Kafka, Amazon SQS, Amazon SNS, and RabbitMQ, and orchestrating batch workflows using ETL pipelines and Amazon Redshift analytics with object storage on Amazon S3. -> Strengthened security, observability, and system resilience by implementing OAuth 2.0 and JWT-based authentication integrated with AWS IAM and AWS Secrets Manager, enforcing distributed caching with Redis, configuring structured logging via Serilog and Amazon CloudWatch Logs and AWS X-Ray, and driving testing excellence through xUnit, Playwright, and TDD practices across Kubernetes-hosted services on Amazon EKS.

-> Delivered end-to-end healthcare and insurance applications across the full SDLC using .NET Core, ASP.NET Core, and React, building modular microservices for claims adjudication, patient data workflows, and provider systems while enforcing HIPAA compliance, secure coding practices, and domain-driven design principles. -> Architected and deployed cloud-native solutions on AWS (Lambda, S3, RDS, EC2), building automated CI/CD pipelines with Jenkins and CodePipeline, containerizing services with Docker and Kubernetes, and implementing resilient messaging workflows using SQS, SNS, Kafka, and RabbitMQ for event-driven processing. -> Drove engineering quality and observability by establishing unit and integration testing with xUnit and Selenium, configuring centralized monitoring through Grafana and CloudWatch, securing APIs with OAuth 2.0 and JWT, and maintaining structured documentation via Swagger/OpenAPI to support governance and cross-team collaboration.

-> Designed and developed P&C insurance policy management and coverage processing services using C#, ASP.NET Web API, RESTful APIs, SOAP and WCF Services, -> Built scalable insurance and healthcare applications using ASP.NET MVC, ASP.NET Core, and Angular, delivering end-to-end modules for policy administration, claims processing, and quote generation while ensuring compliance with HIPAA, SOX, and GLBA standards. -> Deployed cloud-hosted APIs and automated backend services on AWS (EC2, RDS), securing endpoints with JWT authentication, implementing real-time claim alerts via SignalR, and automating nightly workflows for policy renewals, eligibility checks, and document generation. -> Engineered data pipelines, reporting solutions, and integration layers using SSIS, SSRS, Entity Framework, and PL/SQL to power underwriting insights, clinical dashboards, and structured data exchanges with reinsurance and carrier partners.

-> Assisted in the Full SDLC lifecycle within a fast-paced retail startup environment by gathering feature requirements for e-commerce workflows, contributing to technical design discussions and developing assigned modules for product catalog, checkout and order management systems under senior developer guidance using Agile methodologies. ->Applied foundational Design Patterns such as Repository and Factory to structure reusable and maintainable components supporting shopping cart logic, pricing rules, discount engines and inventory synchronization features within a layered architecture.
