What I’m proudest of is taking a startup from zero to a live production platform with 20+ paying customers within 3 months, built entirely from the ground up: product development, secure SDLC, full-stack delivery, and the AWS infrastructure to run it daily.

Inline Proxy is my open source MCP security gateway: it enforces allow/block/redact/approve policy on every agent tool call and blocks a full prompt-injection exfiltration chain without ever needing to detect the injection itself.

On the offensive side, I designed and ran a prompt injection payload against a Claude Opus 4.8 email triage agent in a controlled lab, achieving successful injection in 8 of 10 attempts while the agent still completed its legitimate task in all 10. I also cleared all 3 escalating levels of Trajectory Labs’ Terminal red team assessment against a hardened PARALLAX agent, including a ticket authority spoof that triggered a privileged password reset. Trajectory Labs’ lab work has found vulnerabilities across Opus 5.5, Fable, Mythos, Gemini, and Argon.

Just applied for the Security Engineer role and it seems like a perfect fit for my background, so I'd love to chat.

AI security engineer. I took a product from zero to production and 40+ paying clients in a month, and I build the controls that stop agents from doing damage once they have real tool access.

What I'm proudest of is an open-source MCP security gateway (Inline Proxy). It sits between an agent and its tools and enforces policy on every call: allow, block, redact, require approval. The case it exists for: a poisoned GitHub issue tells the agent to publish the repo's .env as a public gist. The gateway never has to detect the injection. It only tracks that untrusted content was read, so the exfiltration write gets blocked. Default-deny packs cover 194 tools across GitHub, Jira and Slack, ~0.1ms p99 on the enforcement path, fail-closed. [Inline Proxy repo link]

My master's thesis (UW 2026, ProQuest 32738510) became AegisLLM, an LLM red-team suite mapped to the OWASP LLM Top 10 that uses a genetic algorithm to evolve new attacks. github.com/Harshj143/AegisLLM

Most AI agents ship with tool access and nobody watching what they do with it. I build the enforcement layer that catches it before it becomes a breach.

Inline Proxy: open-source MCP security gateway enforcing per-tool policy (allow, block, redact, and more) on every agent tool call. Taint tracking stops a poisoned GitHub issue from publishing a repo's .env as a public gist. 194 tools covered, ~0.1ms p99, fail-closed by default.

AegisLLM: published as my master's thesis (UW 2026, ProQuest 32738510). Automated LLM red-teaming mapped to the OWASP LLM Top 10, with a genetic-algorithm engine that evolves new attack variants.
