AI Engineering

Building with LLMs, not just around them

I design retrieval pipelines, orchestrate multi-step agents, train domain-specific models, and put all of it behind APIs that hold up in production. The same engineering discipline, applied to a probabilistic stack.

RAG Pipelines

End-to-end retrieval-augmented generation: document ingestion, semantic chunking, embedding, vector search and grounded generation with citations, built so answers stay traceable to source.

  • Chunking
  • Embeddings
  • Vector DBs
  • Hybrid search

Agentic Workflows

Multi-step agents with LangGraph: stateful graphs, tool calling, routing and human-in-the-loop checkpoints, so an agent can be reasoned about and debugged rather than just prompted at.

  • LangGraph
  • Tool calling
  • State machines
  • Guardrails

LLM Application Layer

Dynamic prompt templates, structured output, streaming responses, token budgeting and evaluation loops: the layer that decides whether an AI feature is shippable.

  • LangChain
  • Structured output
  • Streaming
  • Evals

Custom Models & OCR

Trained a domain-specific model for electrical-diagram OCR and component counting at OpenDrawing. Thousands of drawings processed at 90%+ accuracy, replacing days of manual takeoff.
