Systems Engineer·Rust Developer·Kanyakumari, India

Dhanush S

Systems engineer focused on memory safety, concurrency, and Linux internals. I write Rust for production work and C/C++ when the runtime matters more than the toolchain. Currently building Clippy — a cross-platform clipboard daemon with a custom IPC protocol, shipped across Linux, Windows, and Android.

About Me

CS graduate (2025) from Tamil Nadu with a focus on systems programming and Linux internals. My interest is in the layer where software meets hardware — scheduling, memory layout, IPC, and kernel interfaces — and in building tools that are correct by construction rather than by testing alone.

That interest shaped my primary language choice: Rust. The ownership model eliminates entire classes of bugs at compile time. My main open-source project, Clippy, reflects this — a multi-platform clipboard sync daemon (11 ⭐, 5 forks, GPL-2.0) that ships a Linux installer, a Windows MSI, and a Kotlin Android companion app across 150 commits and 4 releases.

I also built and deployed JustShare, a no-registration file and message sharing service running at its own domain with 143 commits of production history. Outside of work projects, I maintain a Hyprland desktop configuration and study OS internals through OSTEP and The Linux Programming Interface.
