01 — Experience · 2026–Present
BellCorp Studio
Associate Software Engineer Intern · Kanpur, India (Remote)
01
Admin Console (Govt of India / Ministry of Finance B2B Marketplace): led delivery of a production module in under a month, directing 5 engineers across frontend and backend.
02
Built zero-trust auth + KYC — RBAC and 3 verification pipelines (GSTIN, PAN, bank) with JWT refresh-rotation and inline PDF preview in React.js.
03
Automated vendor onboarding via a state-machine approval pipeline with bulk approve/reject and an O(1) lazy-loaded category tree + server-side search in Express.js.
04
Established zero-downtime CI/CD on Azure Static Web Apps; migrated to TypeScript with GitHub Actions.
05
Community Platform: virtualized an infinite-scroll feed (TanStack Virtual + per-row memoization) for a flat, constant-size DOM.
06
Fixed a platform-wide notification failure by reference-counting shared Pusher channels keyed on user ID.
02 — Experience · 2025–2026
Centre for AI & Robotics (CAIR) / DRDO
Research Intern — CMSS-PPR Post-Quantum Signature Scheme · Bangalore, India
01
Designed CMSS-PPR, a novel post-quantum signature scheme (Scopus-indexed journal submission, commended by DRDO scientists) using Non-Affine Ring-Permutation Layers (NARPL) that eliminate MinRank and Gröbner-basis attacks.
02
Implemented the full scheme in Python — keygen, signing and verification across all five NIST security levels.
03
Integrated CMSS-PPR into a Node.js/Express REST auth layer for ~30% lower handshake latency vs conventional TLS under load.
04
Proved algebraic security exceeding Rainbow, UOV and HFE via reduction of UF-CMA security to MQ hardness.

RBAC, three KYC pipelines, and token rotation — without locking real vendors out.
The bug that silently killed every notification on the platform
One shared channel, many users, and a classic cleanup mistake. Here's the fix.
Making a giant category tree open instantly
Thousands of nested categories, and it has to feel instant. Lazy loading to the rescue.
