About

Who I am

I'm a Senior Software Engineer who loves building things that scale and last. From clean GraphQL APIs and event-driven backends to GitOps pipelines and cloud-native platforms — I care deeply about reliability, developer experience, and systems that are a pleasure to operate. I strongly believe the best solution is almost always the simplest one.

Pragmatic by nature, I understand business needs and I'm not afraid to challenge them — I bring opinions to the table, not just implementations. I'm also known for getting up to speed quickly on new and complex codebases, turning ambiguity into clarity fast.

My sweet spot is the intersection of backend engineering and platform infrastructure. I work across the full stack — Node.js, TypeScript and .NET on the backend; React and Vue.js on the front; Kubernetes, ArgoCD, Terraform and Pulumi in the cloud. I'm a firm believer in the SRE mindset: if it's not observable, it's not production-ready.

Outside of work I run a personal homelab with cloud and local Kubernetes clusters — exploring self-hosted tooling, AI integrations and whatever technology catches my curiosity next. Continuous learning isn't a buzzword for me; it's how I operate.
