Building ethical security tools
with AI + automation.

Cybersecurity grad student focused on AppSec and practical tooling. I build projects that are recruiter-readable, engineer-usable, and designed with clear ethical guardrails.

Quick highlights
  • Shipped three portfolio-grade projects (tools + browser extension)
  • Ethical scope boundaries + safe-by-design defaults
  • LLM usage behind flags + reproducible output formats

Projects

Shipped projects — each with a clear problem statement, usable output, and honest scope.

WebSentry AI

AI-assisted web application security reviewer (permission-only, non-destructive).
PythonPlaywrightCLIHTML/JSON Reports
What it does
  • Guided security review workflow focused on common web weaknesses
  • Produces prioritized, human-readable findings with mitigation guidance
  • Optional LLM support behind a feature-flag for safe, controlled usage
Security & ethics
  • Permission-only testing with clear scope limits
  • Lightweight checks (no brute force / no destructive actions)
  • Transparent scope: analysis tool, not a vulnerability scanner

PQC-Sim

Post-quantum cryptography KEM benchmarking dashboard with exportable results.
PythonliboqsBenchmarkingDashboardJSON Export
What it does
  • Runs local KEM benchmarks and compares performance across algorithms
  • Displays results and exports JSON for analysis
  • Built end-to-end as a portfolio-grade security + crypto project
Security & ethics
  • Benchmarks computed locally (no private crypto workloads sent to a server)
  • Designed for education + performance comparison use cases

PhishGuard – Chrome Extension

Lightweight Chrome extension that helps users assess suspicious links and websites while browsing.
Chrome ExtensionsJavaScriptManifest V3Client-side logic
What it does
  • Surfaces visual indicators for potentially suspicious URLs and page characteristics
  • Helps users pause and evaluate links before interacting with them
  • Designed for browsing awareness rather than automated blocking
Security & ethics
  • Privacy-first by design: no browsing data is transmitted externally
  • Advisory tool only — assists decision-making, does not label sites as malicious

About

I’m Jerold (Jay), an M.S. Cybersecurity graduate student with an emphasis in Artificial Intelligence. I build practical, ethical security tooling that uses AI and automation to help engineers understand risk, reproduce issues reliably, and implement fixes that meaningfully reduce attack surface.I previously worked as an Associate QA at Amazon Development Center, where I gained experience working with production systems and test automation. My current focus areas include application security reviews, AI-assisted security tooling, secure automation, browser-based security extensions, and post-quantum cryptography.
