The problem
AI learning tools can produce plausible explanations without exposing how concepts, sources and prerequisite order relate.
My role
I lead the product strategy and build the knowledge-graph pipeline, AI evaluation system and full-stack learning product.
Key decision
Keep concepts, sources and prerequisite structure inspectable instead of hiding them inside model output.
Outcome
A live product that turns curated material into an explorable graph and uses that structure to guide a learner through a difficult topic.

  • Next.js
  • Postgres
  • Knowledge graphs
  • LLM evaluation
