EXPERIENCE

Software Engineer II

Poolcorp

May 2026 ‐ Present

  • Drove key improvements to the Hub - an Azure Service Bus / Cosmos DB event-processing backbone that propagates data changes from source-of-truth systems across the enterprise; delivered significantly higher throughput, lower latency, and improved uptime
  • Upgraded solution to the latest .NET and Azure Functions runtime; migrated to the current Cosmos DB SDK with bulk processing enabled, reducing per-operation overhead at scale
  • Enhanced observability through structured logging improvements and expanded unit and integration test coverage across critical event-processing paths
  • Applied DDD and SOLID principles through targeted refactoring, establishing clearer bounded contexts and improving long-term maintainability
  • Adopted AI-assisted development workflows using Claude Code and spec-driven tooling (GitHub Spec Kit, OpenSpec) to accelerate feature delivery and maintain specification quality

Software Engineer II

Poolcorp (via OpenArc)

July 2025 ‐ April 2026

  • Contributed to the design and ongoing development of a new Azure-based order fulfillment service that modernizes legacy workflows and improves reliability and resiliency through Clean Architecture and Domain Driven Design (DDD)
  • Implemented serverless Azure Functions integrating Azure Service Bus (topics/queues), Azure Table Storage, and Azure App Configuration for event-driven orchestration
  • Advocated for and implemented xUnit and Moq-based unit and integration tests, increasing confidence and safeguarding critical fulfillment flows

Application Developer II

MWI Animal Health

June 2022 ‐ July 2025

  • Spearheaded project to redesign core backend API solution to implement Vertical Slice Architecture and CQRS design pattern
  • Extended functionality for ASP.NET MVC / Sitecore-based ecommerce solution used by hundreds of veterinary clinics nationwide
  • Wrote xUnit and Moq-based unit and integration tests covering new and existing functionality to increase confidence in the code base
