Profile

Platform Engineer with 5+ years building and operating production systems — from full-stack applications to the infrastructure that runs them.

I recently completed a Cloud & DevOps specialization and built Barnati, a sovereign multi-tenant infrastructure platform designed for UHNWI clients requiring absolute data isolation. The stack runs on Kubernetes (Scaleway Kapsule) with GitOps delivery via FluxCD, Crossplane for infrastructure reconciliation, Traefik, External Secrets, and Datadog for full-stack observability — fully automated, zero-touch, drift-free.

I am relocating to Switzerland and targeting Platform Engineer or SRE roles, ideally within fintech, SaaS, or privacy-sensitive industries where infrastructure quality is a competitive advantage. Open to opportunities in Geneva, Zurich, or remote from Switzerland.
