$ specialisation —

Electro Surgeon crafting silicon from scratch. Building an 8-bit CPU in Verilog, breaking CTF challenges, and exploring quantum superposition — all from a Fedora + Hyprland rig in Andhra Pradesh. Future: VLSI engineer → Hardware Security → Quantum.

About Me

I'm a 3rd-year Electrical and Electronics Engineering student at JNTU Kalikiri (JNTUACEK) with a clear trajectory: VLSI design first, then hardware security, then quantum. I don't spread thin — I go deep.

My flagship project is the Chameleon CPU, an 8-bit processor being built from first principles in Logisim Evolution and Verilog. The ALU is complete with 17 operations, carry lookahead logic, and full flag generation. Registers and control unit are next.

On the security side, I've completed all 7 levels of OverTheWire Leviathan — SUID exploitation, symlink attacks, binary analysis with ltrace, and bash-scripted brute force. TryHackMe and HackTheBox form my ongoing training ground.

Quantum computing lives in Q-Circuits, where I explore GHZ states, Bell states, and Dirac notation — connecting quantum gates to classical CMOS logic from an EEE perspective.

🔐 CTF Writeups

Full writeup series for OverTheWire: Leviathan — all 7 levels completed. Covers Linux privilege escalation, SUID binary exploitation, symlink attacks, ltrace-based binary analysis, bash brute-forcing, and binary-to-ASCII decoding.

⚛️ Q-Circuits

My quantum computing exploration. Implements a 4-qubit GHZ state demonstrating maximal entanglement, Bell state experiments, and Dirac/bra-ket notation analysis. Bridges quantum gate theory with classical VLSI design principles.
