Designed and built scalable backend and cloud-native solutions across multiple enterprise clients using .NET (Core/6/8), C#, Azure, and modern architecture patterns.

• CrashChampions (Automotive): Developed CAMS backend using ASP.NET Core, EF Core, CQRS, and Azure services (Service Bus, Durable Functions, Blob Storage) to support high-volume calibration workflows with real-time monitoring via Application Insights.
• Dynata (Data & Insights): Built a distributed ingestion platform using .NET 8, Azure Functions, and Service Bus, enabling resilient, high-throughput asynchronous processing with EF Core Code-First schema management.
• QTC (VA Healthcare): Modernized legacy .NET systems by refactoring Windows Services, migrating SSRS workloads, and implementing queue-driven API workflows optimized for cloud-ready processing.
• WEX (Fintech): Improved performance in hybrid .NET 4.8 / .NET 6 systems by tuning SQL, optimizing SSRS pipelines, and diagnosing production issues using DataDog and Azure telemetry tools.
• ServiceChannel (SaaS): Enhanced backend search performance using EF Core, Redis, Elasticsearch, and strengthened cloud stability via improved observability, distributed caching, and automated testing.
• Juniper by IMC (E-Commerce): Rebuilt and cloud-enabled APIs from .NET 3 → .NET 6, including the JuniperCredit service built with Refit, FluentValidation, and CI/CD automation for scalable Azure deployment.

Developed enterprise-grade Release and Defect Management platforms for mortgage and loan operations using .NET Core, ASP.NET Core, GraphQL(HotChocolate), and Clean Architecture.

• Delivered high-volume financial data ingestion and transformation pipelines using EF Core, Dapper, BulkExtensions, Azure Blob Storage, and FluentValidation, supporting complex Excel/CSV templates across institutions (GNMA, Freddie, Warehouse, JPMorgan, Wells Fargo).
• Implemented async and real-time workflows with Hangfire, Worker Services, SignalR, integrating financial process automation via ADF, FedEx WCF, MimeCast, and Azure services (Azure AD, Key Vault, Application Insights).

Modernized enterprise guest-services platforms by unifying multi-service environments and supporting the transition of legacy .NET systems into modern, cloud-ready architectures.

• Built a cross-platform Docker Compose environment for Drupal, Scala, and .NET 4.8 services, improving environment consistency and enabling faster onboarding; implemented HAProxy routing/load balancing to support phased migration from legacy reservation systems.

• Contributed backend integrations for the Vue.js 2 Deck Plan Explorer and established structured engineering documentation using GitHub Wiki and Confluence, strengthening developer workflow and platform reliability.

Delivered a unified WCF + Entity Framework API on Azure to streamline cross-region CMS communication and modernize provider and claim workflows.

• Engineered an end-to-end Azure-hosted WCF API backed by Entity Framework, consolidating disparate CMS systems and improving system interoperability and operational reliability across regions.
• Built the provider registration capability and modernized the Web Claim Submission portal using ASP.NET Web Forms, Bootstrap, jQuery, and WCF services, delivering a responsive, mobile-ready experience that accelerated claim processing.

Supported development and stabilization of the S.P.I.R.I.T. health insurance platform, enhancing reliability, performance, and feature delivery across core operational workflows.

• Improved platform robustness by delivering new backend capabilities, resolving defects, and optimizing performance within the integrated C#, Entity Framework, WCF ecosystem.
• Led full-cycle development of the Accounting/Finance module’s Agents Commission engine using C#, Entity Framework, WPF, WCF, and complex SQL stored procedures, implementing precise commission-split logic that ensured accurate credits, debits, and payouts for agents and agencies.

Maintained and enhanced the STARS contract & tariff management platform, improving reliability, modernization, and operational efficiency.

• Modernized legacy components by introducing Entity Framework and ASP.NET MVC, strengthening maintainability and enabling cleaner data-driven workflows.
• Enhanced backend functionality using ASP.NET Web Forms, C#/VB.NET, and Telerik UI, delivering new contract-tracking features and system improvements that increased transparency and user efficiency.

Designed and optimized mission-critical underwriting and claims management systems, driving legacy modernization and performance improvements for data-intensive workflows.

• Engineered high-performance data modules using C#, Windows Forms, and ADO.NET, leveraging optimized SQL Server stored procedures to maximize system throughput and data reliability.
• Spearheaded legacy modernization initiatives by migrating VB codebases to C# and implementing LINQ for data validation, while delivering enterprise-grade reporting solutions via Visual Studio Report Tools.
