About

Backend & cloud-native engineer focused on performance and event-driven design.

I'm a Software Engineer with 4 years of experience building backend and cloud-native applications using C#, ASP.NET Core, Azure, SQL and Angular.

I specialize in API modernization, performance optimization, asynchronous processing and event-driven architectures — reducing API response times from 4–6 seconds to <1 second and optimizing workloads that process 400K+ records.

Currently a Software Engineer 2 at Danaher (Radiometer), I work on AQURE, lead .NET 10 migrations of Azure Functions and drive code quality with SonarQube & Mend.
