Open to internships — Offensive Security & Penetration Testing

Cybersecurity Lead · Penetration Tester · Tool Builder

Your attack surface has gaps. I find them before threat actors do.

I don't just learn security — I build tools that automate it, design CTFs that simulate real attack chains, and run workshops that turn passive users into security-aware professionals. If your team needs someone who thinks like an attacker and communicates like a collaborator, that's the gap I fill.

500+ Participants trained via CTF & workshops
₹2L+ Sponsorship secured cold B2B outreach
5+ Security tools shipped open source, production
50+ GitHub stars on Crecon alone

Skills & Tools

What I bring to your security team — tools I operate, techniques I apply, systems I've worked in.

Security Tools

Script Literacy

PythonBashC (DSA)

I read and adapt scripts — I know what every module does, what a function is trying to achieve, and how to modify it. Security is the skill. Code is the tool.

Experience

What I've delivered — not just what I've learned.

Cybersecurity Lead

IgniteX Club, RCCIIT

Oct 2025 – Oct 2026
  • Directing cybersecurity strategy for a 100+ member club — turning passive learners into hands-on practitioners through structured programs and real attack simulations
  • Designed and delivered technical events that created measurable security awareness across the campus, reaching 500+ students in under 6 months
  • Mentoring juniors on offensive techniques, tool development, and CTF methodology — building a pipeline of security-ready talent

Cybersecurity Day Organizer ★ HoD Award

IgniteX Club, RCCIIT

Mar 2026
  • Organised a 100+ attendee security event with zero slides — opened terminals instead. Live password cracking demos with Hydra and John the Ripper changed how the room thought about security
  • Earned Certificate of Appreciation from the HoD, Department of IT, RCCIIT — recognition for measurable impact on campus security culture

CTF Organizer — Stranger's CTF ₹2L+ Secured

RCCIIT — Techtrix '26

2026
  • Cold-pitched infosec companies (Altered Security, APIsec University, .XYZ Domains) with a professional B2B deck — secured ₹2 Lakhs+ in sponsorship, entirely through direct outreach
  • Architected 20+ custom challenges covering SQLi, XSS, auth flaws, crypto, and OSINT — simulating real-world attack patterns across skill levels
  • Deployed and managed a custom CTFd platform on resource-constrained VMs, optimised for 500+ concurrent participants without downtime
  • Officially listed on CTFtime — putting RCCIIT on the global competitive hacking map

// flagship project

Main Project

A tool built to replace manual recon workflows — the kind of thing your pentesting team would actually use.

crecon
★ Flagship Tool v0.1.0
⚡ One command. Full recon. Nmap → CVE lookup → SSH testing → directory brute-force → web crawl → Nuclei → AI-generated attack paths with exact payloads. Zero manual chaining.

Automates the first phase of every engagement. Port 80 open → triggers directory brute-force, web crawl, Nuclei CVE validation automatically. Port 22 open → auto-tests default SSH credentials. NVD CVE lookup fires on every detected service version. All findings are piped to an AI layer that generates actual attack paths — not generic advice, but exact commands and payloads.

Supports 5 AI providers (DeepSeek-R1, Groq, Gemini, OpenAI, Anthropic) with automatic fallback. Installable as a native Kali Linux command. Built for real engagements, not demos.

// case-based projects

Case-Based Projects

Focused tools built to solve specific gaps — each one deployable in a real security workflow.

SafeWall IDS / Monitor

Real-time network security monitor your SOC can actually use. Sniffs every incoming packet via Scapy, detects DDoS spikes (>40 pkt/sec), flags malware signatures (SQLi, XSS, Nimda, path traversal), and auto-blocks offending IPs with iptables — no analyst action required.

PythonScapyiptables
IPclean Forensics

Post-incident log auditor. Scans a full directory of log files, pinpoints every file containing a target IP, and optionally wipes them clean — saving hours of manual grep work during forensic cleanup and containment.

Pythonargparseos
expDB Utility

Exploit lookup, zero friction. Reads the software/version from your clipboard and opens ExploitDB pre-filled — cutting the lookup time to seconds during live engagements. Small tool, real time savings at scale.

On The Ground

Security events I organised end-to-end — logistics, sponsorship, platform, challenges, and delivery.

Cybersecurity Day 2026 Workshop
100+ attendees Mar 2026 RCCIIT

Replaced slide decks with live terminals. Walked 100+ students through real password cracking using Hydra and John the Ripper. Earned Certificate of Appreciation from HoD, Dept. of IT — for measurable impact on campus security awareness.

Stranger's CTF — Techtrix '26 CTF Event
500+ participants ₹2L+ prize pool Kolkata

Custom CTF platform, Stranger Things theme, glitchy terminal aesthetic — gutted CTFd's frontend from scratch. Secured ₹2L+ through cold B2B outreach to infosec companies. Officially listed on CTFtime.
