AI engineer building LLM systems, RAG pipelines, and 3D vision tools.

Evidence-based security log review with optional AI

• Python
• FastAPI
• PostgreSQL
• SQLite
• OpenAI API
• Playwright
• Docker

Built a review tool that links gateway requests to explicit authentication outcomes and produces cited facts without a model. Optional AI selects bounded evidence and allowed explanations; invalid selections are rejected without changing the factual baseline. Tested five browser-driven scenarios against a locally instrumented OWASP Juice Shop, checking 182 records across reviews representing 154 unique source records. Missing authentication logs stayed unknown despite HTTP success. Includes immutable case snapshots, separate review/execution permissions, and preserved failure evidence. Alpha prototype, not a validated attack detector or production security service.

Self-hosted LLM platform with OpenAI-compatible APIs

• Python
• FastAPI
• React
• Qdrant
• Ollama
• Docker Compose
• Prometheus
• Grafana

Microservices LLM platform — API gateway, RAG, embedding, and inference services — with an embedding-based semantic cache cutting latency ~80× on cache hits, a difficulty-based router dispatching prompts across Ollama model tiers, a CI quality gate on retrieval metrics (recall@k, MRR), and 16 Prometheus/Grafana panels covering latency, token economics, and answer quality.

Turn AI chat transcripts into a searchable knowledge base

• Next.js
• TypeScript
• FastAPI
• LangGraph
• PostgreSQL
• pgvector
• MinIO
• Docker

Full-stack RAG app converting long AI chat transcripts into knowledge bases, study notes, and concept maps. A 10-node LangGraph pipeline orchestrates Playwright capture, artifact persistence, chunking, and embedding; async job re-architecture took ingestion API responses from 30–90s to ~10ms, with pgvector retrieval at ~50ms, a provider-agnostic LLM factory, JWT auth, and full CI.
