I am a Registered Penetration Tester & Ethical Hacker holding OSCP, CRTP, CEH, and CISSP certifications. I design custom tools and scripts for penetration testing and work extensively with Kali Linux. I perform comprehensive manual testing using Burp Suite, Metasploit, Nmap, SQLMap, Wireshark, and industry-standard frameworks. I safely develop, test, and modify exploits based on target environments. I currently work as a full-time security consultant specializing in penetration testing and vulnerability assessment across web applications, APIs, cloud infrastructure, and mobile platforms. I help organizations identify real, exploitable security risks through black-box, grey-box, and white-box testing methodologies. I have proven experience identifying critical and high-risk vulnerabilities across banking, telecom, insurance, government, SaaS, healthcare, and EdTech platforms. My work has led to multiple zero-day discoveries and CVE records in widely used products, including SHAREit, Upwork Time Tracker, and Avast Anti Virus. I bring 6+ years of hands-on experience as an information security professional. I have led and executed hundreds of penetration tests, VAPT engagements, red team operations, and security audits. My experience spans large enterprises with thousands of assets as well as startups seeking strong security foundations. I have deep expertise in assessing network security, cloud infrastructure (AWS, Azure), API security, web application security, and mobile application penetration testing (iOS and Android) across modern technology stacks.
