System Architect & AI Automation Engineer

Building systems that
run without you.

I bridge the gap between probabilistic AI and deterministic business logic — designing clean, decoupled architectures that scale at the enterprise level without the hype.

"Stop chasing plug-and-play AI platforms. Master the infrastructure beneath them."

Architectural philosophy

🧠
Interaction layer
Probabilistic · The concierge
Multi-turn conversational state, JSON schema extraction from natural input, and synthesizing complex responses into fluent language. Built on LangGraph + FastAPI.
AI never executes business logic directly
🧮
Computation layer
Deterministic · The engine
Raw Python/FastAPI engines and PostgreSQL/pgvector as a single source of truth. Executes models, scores data, enforces business rules. Same inputs — identical results, always.
100% consistency guaranteed
⚙️
Automation layer
Event-driven · The supply chain
n8n for orchestrating asynchronous background jobs: data ingestion pipelines, dynamic scraping, and real-time outbound webhooks — without blocking the main loop.
Never blocks the conversational thread
