Most dev portfolios are just dressed-up résumés.

I wanted mine to feel like a product launch.

Here's how I built it from zero →

Onyx is live with paid plans.

AI-powered API security testing:
→ Paste OpenAPI spec
→ Gemini generates attack payloads
→ Real-time vulnerability stream
→ PDF report export

Free tier available. Pro is $9/mo.

Built this solo during final year of CS.

Securing the Onyx pipeline.

Yesterday's audit revealed an attacker could drain my Gemini API credits by spamming the attack endpoint. Shipped a patch today adding strict IP rate limiting and custom DNS-resolving SSRF guards to block internal network requests.

Standard HTTP polling is incredibly inefficient.

For Onyx, I needed real-time attack telemetry. I wired up native WebSockets to stream the exact millisecond a payload crashes the target server directly into my React frontend with zero lag.
