About me

Hi, I'm Pavan!

I am a low-level software developer obsessed with understanding the "magic" between the hardware and the application. While others build on top of abstractions, I spend my time building the abstractions themselves. Currently, I am deep-diving into OS architecture and the Linux Programming Interface (TLPI).

  • Languages: C, x86 Assembly, C++, Core Java, Python

Featured Project: One Piece

A custom-built, 32-bit x86 monolithic kernel developed from scratch.

  • Real Mode -> Protected Mode -> Long Mode
  • Bootloader: Custom x86 assembly bootloader recognized by BIOS.
  • Memory: Implemented physical memory manager and basic paging.
  • Multitasking: Designed a round-robin scheduler with hardware context switching.
  • The Goal: Achieving full POSIX-compliance for standard utility support.
  • View Repository

Current Learning & Roadmap (2025-2026)

  • Mastering TLPI: Implementing system call exercises from The Linux Programming Interface.
  • Kernel Modules: Writing Loadable Kernel Modules (LKMs) for modern 6.x kernels.
  • High Performance: Implementing cache-efficient data structures in C.
