My work spans disciplines from machine learning and mathematics to quantum computing, but nearly all of it converges on a single theme: cybersecurity. Whether directly security-focused or serving as a technological enabler, each project ultimately feeds back into strengthening and advancing the security landscape.
A password strength analyzer program which can approximate how strong a password is against a quantum computer. Built using Python and Streamlit. Approximates the time taken to crack a given password via three methods.
DNSDino is a sleek, beginner-friendly OSINT web tool that helps you dig deep into any domain name. From WHOIS records to DNS resolution and IP geolocation, DNSDino provides a clean UI and actionable results. It's also a learning tool! It includes a comprehensive course on networks and DNS, with a total of 5 modules on different topics.
A Neural Network built from the ground up using only Python and NumPy. Illustrates how neural networks operate under the hood while also demonstrating how high-level libraries abstract away much of the manual work.
An interactive Bloch sphere visualization tool I made for a seminar on Post-Quantum Cryptography. Used for exploring single-qubit quantum states. Apply quantum gates and watch your qubit evolve in real-time.

I've written multiple articles covering the enterprises of security, internet privacy, and more. I've also penned down a piece distilling my years worth of experience in public speaking.
I publish all of my articles on Medium. Many more coming soon!
My favorite recorded talks can be found below.
The inaugural session of CSI Region 7’s Monthly Student Webinar Series. A foundational overview of quantum computing, encryption and quantum algorithms from the ground-up. Watch on YouTube
More coming soon!
I deliver speeches, seminars and talks very often. Below, you can find my upcoming and past speaking engagements and events.
I was invited as a judge for The PSBB Millennium School, Coimbatore's T'XOTICA Tech Event on the 28th of November, 2025. I had the opportunity to judge and provide insights on various student projects based on real world problems.
I had the excellent opportunity to present a seminar on post-quantum technology and encryption to a fantastic audience of thought leaders, professors, working professionals and keen students. You can watch the recording on YouTube! Check the 'Featured Talks' section.
I had the honor of delivering a seminar on 'Quantum Computing and the Future of Cybersecurity' to an audience of over 700+ professionals and students at KPRIET under the wing of OWASP Coimbatore.
I am an 18-year-old Computer Science student with a strong specialization in cybersecurity. I currently serve as an ISEA (Information Security Education and Awareness) Ambassador and as the Secretary of the OWASP Chapter at Sri Ramakrishna Engineering College.
My industry experience includes cybersecurity internships at Zyphron Technologies Pvt. Ltd. and Shadowfox, where I developed technical documentation, conducted Windows and web-based penetration-testing simulations, identified critical misconfigurations, and authored detailed exploitation and remediation reports.
I have delivered a technical talk on Quantum Computing and Cybersecurity to an audience of over 700 participants, and have presented a cybersecurity seminar for the Computer Society of India (CSI). I deliver talks frequently, and never turn down an opportunity to do so. I have also delivered multiple talks in my institution. I rank in the top 1% globally on TryHackMe, reflecting my continuous commitment to hands-on security training and skill development.
My current technical interests include Machine Learning for Intrusion Detection, DDoS attack classification, Post-Quantum Cryptography, and Red Team Operations. I am actively working on ML-based security applications.
