What I'm looking for

I’m looking to keep building high-performance backend systems—especially distributed, event-driven services—where I can own critical workflows and improve search, processing throughput, and reliability end to end.

I’ve spent the last decade building backend platforms in C#, .NET, and ASP.NET Core, from payroll and HR at Deel Local Payroll (powered by payspace) to healthcare systems with Cavista Technologies for Axxess.

On the projects I’ve led, I’ve optimized high-throughput processing (cut retrospective calculation time by 80%), built event-driven workflows with Kafka and Azure Service Bus, and shipped Ask Axxess Smart Search with Kafka + OpenSearch to pull EMR data in under five seconds.
