Senior software engineer at Gainwell Technologies building C# services for a healthcare claims platform and event-driven warehouse systems.

Message

At Gainwell Technologies, I develop C# and .NET applications for a state healthcare claims platform, working across modern services and legacy C and Oracle components. I use the legacy code as the reference for business rules and recover failed batch cycles without breaking dependencies.

At KNOWiNK, I modernized VB.NET and classic ASP.NET components into C# and .NET Core services, and delivered REST APIs and applications on Azure. I also handled release readiness with QA and served as the technical contact during escalated production incidents.

At MHS Global / FORTNA, I built .NET microservices for a warehouse control system, using RabbitMQ and ReactiveX to decouple services so a slow consumer couldn't stop the production line. I also delivered REST and GraphQL APIs and integrations with industrial systems, including robotics control over Redis.
