j143 - Overview

Janardhan Pulivarthi

Systems engineer


🛠️ Tech I’m hands-on with

  • Languages: Java, Bash, Python (for tooling)
  • Infra & Platforms: Kubernetes, Calico, Istio, Envoy, Jenkins
  • Systems: Linux internals, kernel build, networking (Layer 3/4), BPF, Git plumbing

🧩 OSS Contributions

I contribute upstream fixes, test improvements, and build cleanups to core open-source infrastructure projects.

  • Apache – Release management, System Internals, Test cleanup, minor bug fixes
  • TensorFlow – minor bug fixes
  • libgit2 – tests
  • Others – Subtle PRs to CLI tools, runners, and build infra

I'm more interested in fixing quietly than chasing stars. Small PRs. High signal.


✍️ I also write sometimes


🧭 Currently exploring

  • Network observability & service mesh behavior
  • BPF + iptables at scale
  • Building tools that live well in infra
  • Writing cleaner CLIs & internal docs
