Work I'm drawn to

AI where it actually helps: ship the first useful version, wire it into real data, measure it, then make it reusable.

Also called AI product engineering or applied AI engineering.

Retrieval-augmented search

Semantic search across a clinical learning library

Search by meaning, not keywords. Embeddings, pgvector, retrieval strategy, and the rollout.

  • RAG
  • OpenAI embeddings
  • pgvector
  • Postgres
  • Search UX

In production for thousands of clinicians.

Personalized recommendations

Behavior-driven recommendations

Recommendations that follow what members do. Logic, data model, retrieval, and the full-stack integration.

  • Recommendations
  • Personalization
  • Product engineering
  • Content discovery

Assessment-driven personalization

Assessment-to-study-plan pipeline

Assessment misses become targeted study plans. Content mapping, retrieval, reranking, and the UX.

  • Data pipelines
  • Reranking
  • RAG
  • Learning systems

In progress In progress

Personalized retention engine

A daily plan that mixes spaced repetition, recommendations, and retrieval so material sticks.

  • Spaced repetition
  • Retention
  • Personalization
  • Applied AI

How I work

Unclear requirements, legacy constraints, partial data, users who do not care about AI. I turn that ambiguity into reliable product behavior.

  • Frame User pain, constraints, success criteria.
  • Build Prototype fast, then harden what works.
  • Integrate Existing data models, APIs, auth, surfaces.
  • Measure Relevance, adoption, latency, cost, trust.
  • Productize Repeated needs become reusable capabilities.

Tools I reach for

AI / retrieval

OpenAI, embeddings, RAG, reranking, pgvector, evals

Product engineering

TypeScript, React, Node.js, Postgres, GraphQL/REST

Production reality

Observability, auth, performance, cost/latency, debugging

Also shipped

Rails, React Native/Expo, native iOS/Android, Go, Python
