- spent the last decade building and operating event-driven .NET systems, messaging-heavy services, internal platforms, and tooling
- worked across travel/customs integrations, finance & loan-management platforms, telecom/contact-center tooling, and earlier Android/public-sector apps
- care a lot about reliability, observability, and architecture that survives contact with production
- some of my best professional work lives in private company repos, so this profile focuses on the parts I can actually show in public
