Open-source, self-hosted governed-autonomy SRE platform in Go and Temporal. An LLM agent triages infrastructure incidents behind a fail-closed prediction gate, deterministic verdicts, and a SHA-256 hash-chained ledger. Successor to Agentic ChatOps.
The same loop runs servers, minds, and language models — predict, act, be surprised, update — and what keeps it honest is an error channel it does not fully control
What I'm currently focused on — updated regularly.
Three agentic subsystems that triage alerts, investigate root causes, and propose fixes across 300 objects and 5 sites — governed by a self-monitoring control plane and a Kubernetes-style self-healing controller, with a human always in the loop and no remediation reaching approval without a machine-computed prediction. A across 9 agentic-AI rubrics; B vs published agent-engineering standards.
Interactive chaos engineering on production infrastructure. Kill VPN tunnels and DMZ services in real-time — watch BGP failover, HAProxy backend switching, and automatic recovery. Continuously baselined with multi-perspective measurement from all 5 sites (NL, GR, NO, CH, TX).
An IETF Internet-Draft specifying IP datagram transmission over unanswered GSM ring signals. 1.6 bps. Eight phones. No one answers. This is the physical layer.
Open-source gateway bridging Meshtastic LoRa mesh networks to Iridium satellite via SBD. One device, unlimited mesh nodes, €15/month.
Territory Grounder, CubeOS, MeshSat, and MuleCube — open-source tools for governed SRE autonomy, self-hosting, satellite mesh networking, and offline knowledge.
Hybrid Kubernetes cluster with a BGP-anycast edge spanning five countries for global traffic distribution and automated failover
The site you're on. Hugo static site with a status page where visitors can kill real VPN tunnels and watch the infrastructure fail over.
