About

👋 Hi there! I'm Varun Punia, a final year CSE student at MAIT. I'm deeply passionate about problem-solving, philosophy, and competitive programming. Beyond coding, I find joy in crafting compelling narratives through video editing, and I've even created a YouTube video where I tackle a hard LeetCode problem. 🧠 I thrive on the challenge of pushing my limits, having solved over 1200+ DSA problems across various platforms. I'm also enthusiastic about sharing my knowledge, whether it's through mentoring fellow students or creating educational content. 💻 Professionally, I'm well-versed in web development, particularly in the MERN stack. I love building projects that make a real impact while honing my skills as a developer. 🌟 Additionally, I excel in leadership, team management, and event planning. I've successfully managed teams and orchestrated events, leveraging my organizational skills to ensure smooth execution and positive outcomes. 🚀 I'm always eager to learn and grow, and I believe that collaboration is key to innovation. Let's connect and embark on exciting tech adventures together!

Machine Learning Intern

Feb 2025 – May 2025 · 3 mos · Metcalfe House, New Delhi · Hybrid

Worked in the Scientific Analysis Group (SAG) lab, conducting black-box adversarial attacks (FGSM, PGD, Carlini-Wagner) on face recognition systems (FaceNet, ArcFace) to evaluate model vulnerabilities.
Assessed adversarial robustness by measuring attack success rates (ASR), perturbation norms (L2/L∞), and cross-architecture transferability (ResNet, VGGFace2) via adversarial datasets (LFW, CelebA).
Boosted model resilience by 23% using adversarial training, input preprocessing, and transfer learning (VGGFace2, ResNet), preserving baseline accuracy on perturbed inputs.
