6+ years as an Offensive Security Researcher, OSCP and CEH v12 certified, I help startups, SaaS companies, and enterprises think like an attacker before real attackers do through hands-on Penetration Testing, Red Teaming, and Vulnerability Assessment (VAPT) across web, mobile, API, network, and cloud environments. My approach is simple: real offensive security isn't a scanner dump it's manual exploitation, chained attack paths, and a prioritized, developer-ready remediation plan mapped to your actual business risk. With a strong software engineering background, I read source code, trace data flows, and reason about architecture catching business-logic flaws, privilege-escalation chains, and design weaknesses that automated tools always miss. šŸŽÆ PENETRATION TESTING & VAPT Full-scope Vulnerability Assessment and Penetration Testing (VAPT) across the OWASP Top 10, OWASP API Security Top 10, and PTES/OSSTMM methodologies: broken access control, IDOR, SSRF, SQLi/NoSQLi/command/template injection, XSS, CSRF, insecure deserialization, auth/session flaws, privilege escalation, and business-logic abuse.

Tools: Burp Suite Pro, OWASP ZAP, Nmap, Metasploit, Cobalt Strike, Nuclei, sqlmap, Nessus, ffuf, BloodHound, Mimikatz, Hashcat, John the Ripper, Wireshark šŸ•µļø RED TEAMING & ADVERSARY SIMULATION End-to-end Red Team engagements simulating real-world TTPs mapped to MITRE ATT&CK: initial access, phishing simulation, C2 infrastructure, privilege escalation, lateral movement, persistence, and data exfiltration testing people, process, and technology together, not just systems. Purple Team collaboration to strengthen detection and response (SOC/EDR/SIEM evasion & tuning). ā˜ļø CLOUD SECURITY (AWS, Azure & GCP) IAM and least-privilege reviews, network segmentation, exposed storage (S3/Blob/GCS), privilege-escalation paths, and CIS Benchmark hardening.
