About

Professionally, I work as an SRE focusing on Kubernetes infrastructure, service mesh technologies like Istio and Envoy Proxy, and building controllers and operators in Go.

In my free time, I work on systems programming, particularly networking tools and kernel interfaces. I write code that deals with packet capture, process identification, and cross-platform compatibility between macOS, Linux, and Windows.

Professional Work

  • Site Reliability Engineering with Kubernetes
  • Service mesh technologies (Istio, Envoy Proxy)
  • Kubernetes controllers and operators
  • Go development

What I Work On In My Free Time

  • Networking tools and kernel interfaces like eBPF
  • Performance optimization
  • Network analysis and deep packet inspection

Current Projects

  • RustNet: A network monitoring tool with experimental eBPF support
  • FFmpeg Exporter: A Prometheus exporter using FFprobe to expose metrics about media streams (SRT, HLS, RTMP, RTSP)
  • Various contributions to networking and systems tools

Interests

  • eBPF programming and kernel tracing
  • Differences between macOS PKTAP and Linux networking APIs
  • Rust for systems programming
  • Real-time packet processing
  • Cross-platform compatibility
