Human logic,
machine defense.

Prasiddha Paudel / Secure Backend · LLM Integration · AI Security

I build the layer that sits between people and AI — secure LLM gateways with prompt-injection defense, rate limiting, and full audit trails. Fast, hard to break, and provable in production.

PROFILE

Security-first, from the backend to the model.

I'm an AI-focused software engineer with 5+ years building secure backend systems and RESTful APIs, now working hands-on with LLM API integration and secure AI pipeline design in Python/FastAPI and Java/Spring Boot.

My application-security background — CompTIA Security+, ISC2 CC, and OWASP Top 10 — is exactly what LLM systems are missing. That combination lets me build and secure AI features at the same time: prompt-injection defense, secure LLM gateways, and AI-integrated security tooling.

Right now I'm shipping a portfolio of production AI-security tools running live on AWS.

SYSTEMS · LIVE ON AWS

Production AI-security tooling.

Three builds that put the security layer where AI actually needs it — the gateway, the SOC, and the code review.

Secure LLM API Gateway LIVE

A production Spring Boot 3 gateway that proxies OpenAI and Anthropic calls through a 5-layer security pipeline — JWT auth, Redis rate limiting (20 req/min), prompt-injection detection, provider proxying, and output sanitisation — addressing OWASP LLM Top 10 #01 and #05. Every request is audit-logged async with SHA-256-hashed prompts, and a Strategy-pattern router adds new providers with zero gateway changes.

SentinelAI — LLM Security Operations LIVE

An AI-driven SecOps platform pairing red-team recon and vuln analysis with blue-team log analysis and threat correlation, powered by Claude with real-time WebSocket streaming. A multi-log correlation engine cross-references Apache, SSH, Nginx, and Windows Event logs to reconstruct full attack chains across vectors, then exports PDF reports. 12 endpoints live, covering the OWASP API Security Top 10.

Vibe Code Security Auditor IN PROGRESS

An AI code-security auditor that scans uploaded codebases or GitHub repos, returns a 0–100 security score, and produces line-level findings with suggested fixes. It targets a real and growing gap: AI-generated code shipped to production without a security review.
