"Digital evidence doesn't lie. It just needs the right analyst to make it speak."

I'm a postgraduate student at NFSU Goa, one of India's leading forensic science institutions. My work covers mobile device forensics, network analysis, incident response, and security tooling. I approach it the way an investigator would: methodical, precise, and grounded in evidence.

I completed a forensic internship in the Forensic Electronics Department at the Central Forensics Science Laboratory, Chandigarh, from 3rd June to 3rd July 2026, under the mentorship of Ashmit Sharma, Scientist B. I've also worked at Netsmartz on cybersecurity operations and at Super Student on quality assurance. I compete in CTFs regularly and build open-source tools that support forensic investigation work.

My BCA from Amity University (77.1%) gave me the programming and systems foundation I now build on in my forensic research at NFSU Goa.

Projects

CASE #SEC-002

Encryption, Steganography & Face Recognition

A Python project combining file encryption, image steganography for covert data embedding, and face recognition, all built into a single Tkinter GUI. Designed as a hands-on exploration of applied cryptography and computer vision.

CASE #DF-003

Video Metadata Extractor (CCTV Edition)

Built during my CFSL internship to cut manual documentation time on large batches of CCTV footage. A single-file, fully offline HTML tool that never touches the original evidence: pulls metadata, extracts frames, reads timestamps via OCR, and hashes files for integrity. Now used on live cases at CFSL.
