SanjayanV:x:1337:1337:AppSec Researcher,Bug Bounty Hunter,CVE Author:/home/SanjayanV:/bin/zshI break things before the bad guys do.
Application security researcher focused on supply chain attacks, web exploitation, and CI/CD security. I hunt bugs, write CVEs, and build tools that make attack surfaces visible.
Production-grade authentication library in Go
A fully open-source auth framework implementing JWT, session-based auth, OAuth 2.0/OIDC, and API key management — designed as both a portfolio piece and a teaching resource for secure implementation patterns.
├── JWT (HS256/RS256, revocation strategies)
├── Session management (stateful, lifecycle hardening)
├── OAuth 2.0 / OIDC integration
├── API key management
└── CI/CD pipeline (SAST · Secrets · SBOM · Trivy · Dependency-Check)
🛡️ ChainSentry (In Development)
Supply chain security monitoring tool
Built on the methodology that discovered CVE-2026-0933 — ChainSentry detects malicious patterns in lockfiles, dependency manifests, and CI/CD pipeline configs before they reach your build.
Target attack surfaces:
package-lock.json · pnpm-lock.yaml · yarn.lock
.github/workflows · Dockerfile · requirements.txt
