What I'm looking for

I’m seeking a backend engineering or technical evaluation role.

On the MOSIP UIN Registration & Voluntary Deletion project, I’m engineering a Spring Boot identity portal with demographic, parental, and cryptographic hash data isolated across three PostgreSQL databases. I implemented salted SHA-256 verification across 1,000 salt buckets without persisting plaintext UIN values.

For the Child Health Record Booklet offline PWA, I architected IndexedDB data collection and syncing, integrated eSignet authentication, and built REST endpoints with validation and retry routines. I’ve also built a CNN classification model as a Machine Learning Intern at CodTech IT Solutions Pvt. Ltd.
