  • 🕹️ Loves doing CTFs, especially pwn challenges (binary exploitation, memory corruption, reversing)
  • 💻 Strong focus on Linux internals, Assembly, C, and Python
  • 🧩 Curious about how things work under the hood

🏆 Achievements

-🥇 1st Place – CodeGuru Extreme (2026) National Cyber Competition (1st / 174 teams)

🛠️ Tools & Skills

  • Debugging: gdb + pwndbg
  • Reverse Engineering: disassemblers, Ghidra
  • Exploit Writing: pwntools

🚀 Projects

🔹 Custom Torrent-like P2P System

  • Built in Python with sockets, threading, bitfield-based piece scheduling, and hybrid RSA+AES encryption
  • Includes tracker + peers (both seeding & downloading)

🔹 Debugger – A GDB like debugger written in C

  • Supports multiple breakpoint types, instruction-level stepping, disassembly, ELF parsing, full CPU register inspection, and process memory inspection.
  • Working on rewind execution feature based on Copy-On-Write memory snapshots, for tracking modified pages to efficiently restore previous execution states.

🔹 Assembly Game

  • A low-level game written in x86 Assembly, focusing on optimization, memory control, and graphics logic
