# Featured Projects

I showcase six AI‑powered developer tools that I built as LangGraph agents with strong safety and security guardrails. Each project includes a short tagline, core capabilities, quantitative results, and the tech stack I used.

- **DeployMate AI** – 7‑agent LangGraph copilot that turns a brief + OpenAPI spec into requirements, field mapping, architecture, test plan, risk register and a handoff doc in one run.

DeployMate AI was evaluated on **40 cases** and achieved **100% architecture validity**.

OpsPilot AI obtained **98% retrieval Recall@5**, **99.6% groundedness**, and **84% task completion** on 50 scenarios.

Toolgate covers **10 threat scenarios** mapped to named tests.

RAG‑Guard’s synthetic drift benchmark improved recall from **71.7% to 100%** and reduced hallucination from **1.7% to 0%**.

PR Sentinel enforces **12 security rules** plus LLM review.

Postpilot was validated with **46 offline tests**.

- **OpsPilot AI** – Incident‑investigation agent with RAG over 20 runbooks, JWT RBAC, SQL allowlisting, PII masking and admin approval before any change.
- **Toolgate** – MCP data‑governance agent that enforces role‑based column grants, row filters and masks server‑side.
- **RAG‑Guard** – Retrieval‑quality gate that detects degraded retrieval and auto‑escalates through BM25, hybrid RRF and keyword fallbacks.
- **PR Sentinel** – Secure CI‑compatible code‑review automation with HMAC‑verified webhooks and idempotent processing.
- **Postpilot** – Human‑approved social agent that orchestrates research‑to‑publish flow with checkpointed approvals.
