About

🔐 Hello! I’m Harsh Sandilya aka rooter09 cybersecurity researcher, full-stack developer, and digital strategist with 3+ years of experience across offensive security, secure development, automation, UI/UX design, and digital growth. I specialize in building secure, scalable, and intuitive systems that blend technical precision with real-world impact. 🛡️ In the field of cybersecurity, I focus on Vulnerability Assessment & Penetration Testing (VAPT), reconnaissance automation, CVE analysis, bug bounty hunting, and OSINT. I’ve responsibly disclosed vulnerabilities through platforms like HackerOne, including a Wildcard CORS Misconfiguration on recreation.gov under the Gold Standard Safe Harbor. I also develop internal security tools using Python, FastAPI, Bash, and PyQt5 to enhance red teaming workflows and threat analysis. 💻 As a developer, I’ve successfully delivered over 100 websites and SaaS platforms using Next.js, React, Tailwind CSS, MongoDB, and WordPress - integrating SEO, security, and performance best practices into every build. 📈 On the digital marketing side, I execute full-funnel growth strategies involving SEO, ad campaign management, automation pipelines, and performance analytics to help businesses scale effectively and securely. 🎨 In UI/UX and creative design, I create clean, responsive, and user-friendly interfaces using Figma, Adobe XD, Photoshop, and Illustrator. I've also trained over 1800 students through bootcamps on cybersecurity, design thinking, and career development. 🎓 As Club Secretary at Amity University Patna, I lead the technical direction for Amikriti, Amikoders, and Amikicks, and was the organizing head for the university’s first official hackathon – HACKIT. My work blends leadership, innovation, and community empowerment. ⚙️ I am currently building a cross-platform cybersecurity toolkit (Web, GUI, and CLI) designed to automate recon, vulnerability scanning, payload fuzzing, and reporting - optimized for both ethical hackers and enterprise security teams. 🧠 Core Expertise: Cybersecurity • VAPT • Red Teaming • Bug Bounty • OSINT • Full-Stack Development • CVE Research • UI/UX • DevSecOps • SEO • Branding • Automation • Public Speaking • Security Tool Development. I’m always open to collaborate, consult, or co-create on security products, startup ideas, automation tools, or digital strategies that make a real-world difference. Let’s connect and collaborate on something impactful.
