.NET Developer Resume Preview
- Designed and built a claims processing API in ASP.NET Core that handles 8,000 requests per minute, serving as the backbone for a health insurance platform used by 2 million members across 3 states
- Migrated a legacy WCF service layer to ASP.NET Core Web API over 5 months, replacing 35 SOAP endpoints with RESTful equivalents while maintaining backward compatibility through a gateway adapter pattern
- Implemented an event-driven architecture using Azure Service Bus and background workers that process insurance enrollment events asynchronously. Processing throughput increased from 500 to 3,000 events per hour
- Optimized slow Entity Framework queries by rewriting LINQ expressions, adding composite indexes, and implementing query splitting for complex joins. Average query execution time dropped from 1.2 seconds to 180ms
- Built a multi-tenant SaaS platform using ASP.NET Core with tenant-level data isolation in SQL Server, supporting 40 enterprise customers with customizable business rules and branding per tenant
- Set up a CI/CD pipeline in Azure DevOps with build validation, unit test gates (1,200+ xUnit tests), and automated deployment to staging and production slots. Deployments went from weekly manual releases to daily automated pushes
- Created a document generation service using C# that produces PDF reports from templates, handling about 15,000 document requests per day with an average generation time under 2 seconds per document
- Integrated Azure Active Directory B2C for authentication across 3 client-facing applications, implementing token refresh, role-based authorization policies, and MFA enrollment. Security audit findings related to auth dropped to zero
- Wrote a data migration tool in C# that moved 12 million records from a legacy Oracle database to SQL Server with data transformation, validation, and reconciliation. The migration completed over a weekend with 99.97% data accuracy
- Implemented structured logging with Serilog and centralized it in Azure Application Insights, creating dashboards and alerts that reduced mean time to detect production issues from 45 minutes to under 5 minutes
- Refactored a monolithic .NET Framework 4.8 application into 6 ASP.NET Core microservices communicating through RabbitMQ, enabling independent deployment and scaling. Deployment frequency increased from monthly to weekly per service
Languages & Frameworks: C#, ASP.NET Core, SQL Server, Azure
Tools & Infrastructure: Entity Framework, REST APIs, Docker, RabbitMQ
