I've built VulnScanner, a local-first dependency vulnerability scanner that synchronizes NVD, CISA KEV, and EPSS data into SQLite and maps findings through OSV.

I implemented CI policy gates based on severity, KEV, EPSS, and baseline differences, producing JSON, CSV, Markdown, and SARIF reports. My work supports npm and Python lockfiles with offline strict-cache mode, retries, explicit exit codes, and deterministic analysis workflows.

With Crawl-Job, I built a resilient job-data collection platform using APIs, RSS, HTTP, and Playwright fallbacks. I added fingerprint-based deduplication, PostgreSQL persistence, validation, rate-limit handling, health reporting, metrics snapshots, and alert hooks.

I've also developed TeleUserBot, a real-time Telegram ingest and routing system with SQL-backed state, layered deduplication, severity-based delivery, structured logging, restart-safe behavior, and retry paths. I'm pursuing a B.Tech in Computer Science and Engineering with a Cyber Security minor and am seeking entry-level backend, security-automation, vulnerability-management, and selected SOC roles.
