Hi, I'm Harshith Sunku

Build anything, anywhere — from CPU registers to UI, cloud, and AI.
No language barrier. No stack barrier.

About

I work across the entire stack — silicon to cloud. I've written bootloaders in Assembly, kernels and network stacks in C, embedded firmwares, infra tools in TypeScript, AI integrations in Python, web apps in JavaScript, and APIs in everything from Go to Java. Pick the layer, pick the language — I'll meet you there.

Comfortable from the lowest level up:

register / boot  →  kernel / driver  →  systems / network  →  backend / API  →  frontend / UI  →  cloud / infra  →  AI / ML
   Assembly         C, kernel APIs       C, sockets          Python, JS, Go     TS, React        Docker, Proxmox    LLM proxies, AI

What I like building

  • Close-to-the-metal: bootloaders, kernels, TCP/IP stacks, schedulers
  • Performance tooling: profilers, flame graphs, thread-safe loggers
  • Infra glue: SSH key managers, Wake-on-LAN, container orchestration
  • AI plumbing: multi-provider LLM proxies, wearables integrations
  • Educational rebuilds: "let me write this from scratch to understand it"

Selected projects

Project Stack What it does
perflens C, Python Real-time Linux perf profiling streamed to the browser. ARM/x86 agent, zstd-framed TCP, live flame graphs + addr2line source.
proxkey TypeScript SSH key manager for Proxmox LXC & VMs — auto-distribute keys via Proxmox API, no prior SSH access needed.
SimpleRealModeBootLoader Assembly Minimal 16-bit real-mode bootloader. Demonstrates the boot process end-to-end.
SimpleMultiThreadedOS C Educational multithreaded OS — scheduling, memory mgmt, IPC.
SimpleSoftwareBasedTCPIPStack C Software-only TCP/IP stack for learning how the protocols actually wire together.
ThreadSafeCLogger C High-performance thread-safe logging library — async writes, in-memory queue, reverse-order reads.
GenericCShellParserLib C Embeddable CLI parser for C projects — show, config, debug, clear, etc.
Generic DLL Libraries C Embeddable doubly linked list + generic DLL data structure libraries for memory-efficient, in-struct lists.
