Message

At IIT Kharagpur, I worked on a DRDO-sponsored project developing a multimodal secure access mechanism for group-enabled cyber systems. I fine-tuned a pre-trained DeepPrint model for fingerprint 1:1 verification and developed a fingerprint-based group key generation mechanism.

At the Naval Science and Technology Laboratory, DRDO, I developed Embedded C programs and a simulator for subsystem data-packet transmission. I also worked on software testing and validation using the LDRA tool suite.

My projects include a fingerprint authentication system using biometric verification metrics and a YOLOv8 object detection model. I’ve also published four articles with UX Collective on Medium.
