👋 About me

I'm an AI Engineer who owns the whole lifecycle: data → model → API → deploy → monitor. Most "ML projects" die in a notebook. Mine ship, get containerized, get observability, and keep working at 3 a.m.

  • 🧠 Deep learning & LLMs — I've built a GPT-style transformer from scratch (tokenizer → attention → training loop → sampling), so I know what happens under the API call.
  • 🤖 Agentic systems — supervisor / specialist multi-agent architectures with LangGraph, tool use, and human-in-the-loop workflows.
  • ⚙️ Production engineering — FastAPI services, PostgreSQL, Docker, Kubernetes, AWS, and Terraform. Typed, tested, observable.
  • 🔬 Currently cooking — an LLMOps platform with auth, migrations and eval loops, a local-first knowledge-graph explorer for the history of ideas, and a simulated community of AI-research agents that argue their way to a spec.
