I built and shipped Project Hub, a full-stack MERN marketplace where I handled the complete development lifecycle in 8 weeks—from requirements to deployment. I added dynamic search and filter functionality using REST APIs and secured buyer/seller flows with JWT-based, role-based protected routes.

In parallel, I developed a real-time object detection system using YOLOv5 and OpenCV, processing camera feeds with bounding-box visualization and object class labels. I also delivered a fraud-detection ML model with Logistic Regression, using SMOTE to address class imbalance and reaching a 0.91 F1-score on the fraud class.

As an Artificial Intelligence Intern at Internz Learn, I worked on a face recognition system in Python and OpenCV, building image preprocessing and feature extraction pipelines and debugging model performance with iterative adjustments. I’m currently completing my MCA and looking for a Software Engineer / Full-Stack Developer role where I can apply system design and problem-solving from day one.
