Hi — I’m Alex

I focus on how systems fail — and how to keep them working when they do. Most systems work until they don’t. I work on what happens next.

I build reliability-focused systems in Go — networking, control planes, and infrastructure that must keep working under failure.

My focus is not just on building systems, but on how they break:

• RPC degradation patterns
• retry amplification
• failure propagation across distributed components

Recently, I’ve been exploring blockchain infrastructure from a systems perspective: Ethereum nodes, JSON-RPC behavior, and oracle reliability.

• vpn-router-daemon (vpnrd)
  A local VPN control plane designed to enforce network policy even when the tunnel fails.

• lanstreamd
  A streaming proxy that maintains continuity under unstable or adversarial network conditions.

• Reliability Notes Series
  Explorations of how distributed systems degrade: RPC failures, retry storms, and incident patterns.

• Multi-uplink resilience
• Failure-aware routing
• Transport continuity under degradation

Currently exploring failure patterns in RPC and blockchain infrastructure.
