ENGINEERING HIGHLIGHTS
  • 01Built and deployed a document Q&A app that returns page-level cited answers and declines out-of-scope questions, through semantic search with a similarity threshold, using pgvector, Gemini embeddings, and Groq at $0 infrastructure cost
  • 02Kept the app reliable within free-tier API limits through resumable batch embedding, automatic model fallback, and Postgres-backed rate limiting (3 questions per minute per visitor), using Next.js route handlers and Neon
  • 03Shipped with 30+ unit tests, an evaluation harness that scores answer correctness, citation accuracy, and refusals, and CI on GitHub Actions (lint, type-check, tests, build, Docker image)
