> SYSTEM_OPERATOR_DOSSIER
I leverage a deep understanding of the modern attack surface—including Cloud architectures and microservice APIs—to identify and exploit critical weaknesses that automated tools miss.
By combining an adversary mindset with structured penetration testing methodologies (OWASP Top 10, SANS Top 25), I don't just locate vulnerabilities; I demonstrate systemic business risk through high-fidelity, actionable technical reporting aligned with SANS and PTES.
Dedicated to helping organizations build resilience by validating their perimeter, host privilege configurations, and network segmentation defenses through rigorous, manual security assessments.

Offensive Security Labs Specialist
Al Nafi LabsRemote
- Administered offensive security lab environments with Linux server hardening, system troubleshooting, and privilege management.
- Analyzed network protocols (TCP, UDP, ICMP, ARP) and packet lifecycles using Wireshark for anomaly detection.
- Dissected enterprise-style traffic (HTTP/S, DNS, DHCP, SMTP, FTP) and simulated network segmentation strategies.
- Validated custom virtualized environments (routers, switches, firewalls) in security testing scenarios.
Offensive Security Researcher
Independent Bug BountyRemote
- Participated in HackerOne and Bugcrowd bug bounty programs, identifying and reporting critical security flaws.
- Discovered vulnerability patterns in API access controls, authentication flow bypasses, and misconfigured cloud assets.
- Developed custom Proof-of-Concept (PoC) exploit scripts for security research validation.
- Published write-ups and walkthroughs detailings modern web vulnerability validation methodologies.
Penetration Tester
Independent Contractor (Freelance)Remote / Islamabad
- Conducted manual security assessments of web applications, REST/GraphQL APIs, and internal networks.
- Chained vulnerabilities (IDOR, SSRF, SQL Injection, XSS, Auth Bypass) to demonstrate business-critical risk.
- Created custom Python and Bash recon pipelines to automate subdomain enumeration and asset scanning.
- Delivered technical and executive-grade security reports containing clear, actionable remediation guidance.
> PROTOTYPES_AND_RESEARCH
Custom tooling, active directory setups, and web application vulnerability research.
Custom Recon Automation Framework
Built a Python-based reconnaissance pipeline integrating subdomain enumeration, HTTP probing, and vulnerability detection. Greatly reduced manual recon overhead and maximized attack surface visibility during offensive assessments.
Active Directory Lab Environment
Designed and deployed a multi-machine lab simulating enterprise active directory vulnerabilities. Practiced sophisticated techniques including Kerberoasting, Pass-the-Hash, token impersonation, ACL abuse, and privilege escalation paths.
Web Exploitation Research
Researched authentication bypass vectors and insecure API implementations in modern web stacks. Created multiple custom proof-of-concept exploitation scripts to validate flaws in mock systems and live bounty targets safely.
