Hi, I'm Harshith Sunku

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 Multiple languages, AI integrations in Python/Node, web apps, 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.
