About me

Building reliable cloud systems, from API to operations

I'm a Cloud & Software Engineer focused on AWS serverless platforms, backend TypeScript services, and production-grade observability.

I design systems that need to scale, stay observable, and remain maintainable under real production constraints.

Beyond cloud, I build pragmatic AI integrations that improve products and developer workflows without adding unnecessary complexity.
