Backend & Infrastructure Engineer · Systems Architecture · Prague, Czech Republic 🇨🇿

• Microservice architecture — service boundaries, data flows, and event-driven systems
• Security-first design — secure-by-default architecture, zero-trust, and threat modeling
• Kubernetes internals — networking, operators, and platform engineering
• FinTech & payments — my primary domain and the problem space I enjoy most

K4s — a terminal UI for managing K3s clusters

• Going deeper into cloud-native security: mTLS, SPIFFE/SPIRE, policy engines (OPA), and supply-chain hardening
• Designing systems where security and resilience are built into the architecture rather than added afterward
• Contributing to open source across the Kubernetes, observability, and security ecosystem
