Software Engineer building production mobile applications, backend services, and cloud-native systems.

I enjoy turning complex business requirements into reliable, scalable, and maintainable software — from mobile applications and backend APIs to deployment automation and production infrastructure.

My engineering journey spans Flutter, .NET, distributed systems, DevOps, and cloud engineering, with a growing focus on Kubernetes, Platform Engineering, Infrastructure as Code, and cloud-native architecture.
