aka Manav

I am a second-year cybersecurity student with a strong focus on cryptography and red teaming. I am also a rookie in reverse engineering and binary exploitation, actively learning through hands-on practice and competitive CTF challenges.

I regularly participate in CTF competitions and play for L3ak, continuously improving my technical depth across offensive security and problem-solving domains.

ping

A low-level networking utility focused on understanding ICMP packets and network reachability. Built to explore how latency, packet loss, and protocol behavior work under the hood, with an emphasis on learning raw sockets and network internals.

zero-alloc-binary-parser

A high-performance binary parser designed with zero heap allocations in mind. Focuses on memory-safe parsing, efficient data handling, and reverse-engineering–friendly design, making it suitable for CTF challenges, binary analysis, and performance-critical tooling.
