.NET Backend Developer Β· PoznaΕ, Poland π΅π±
Iβm a backend-focused .NET developer with around 6 years of commercial experience, building services, APIs, integrations, and cloud-oriented (AWS) systems in C#/.NET.
I like building systems that are boring in the best possible way: reliable, observable, testable, and understandable when something goes wrong.
My current focus is the intersection of backend engineering, cloud-native infrastructure, and secure AI agents especially around MCP, Kubernetes, approval-gated automation, OAuth, RBAC, auditability, and human-in-the-loop control.
Safe AI-driven Kubernetes remediation, by design.
Observer detects anomalies.
Planner proposes an evidence-backed plan.
Human reviewer approves out-of-band.
Executor runs only the approved digest-bound plan.
Everything is auditable.
