👋 I'm Kerolt

Systems Enthusiast | Performance Enthusiast | eBPF Explorer

I focused on low-level systems, observability, and high-performance engineering, and enjoy exploring the underlying principles of how things actually work.

⚙️ Languages: C++ | Rust | Go

🔬 Interests: Operating Systems, Runtime/Scheduling, Observability Tools.

  • 🧊 Systems: Deep diving into eBPF, OS kernels, runtimes, and resource scheduling.
  • ☁️ Cloud Native: Building high-availability distributed infrastructure.
  • 🔬 Observability: Implementing profiling, tracing, and performance toolchains.

🔥 Love things that are full of life and pursue freedom

🏸 Off-keyboard: Badminton, Running
