Your App's Model Client

Build the single typed module every feature in your app calls, so no component ever touches a provider SDK directly: timeouts, retry, cancellation, a structured error taxonomy, and a per-call cost ledger.

Streaming Chat, Done Properly

Build the streaming chat surface most people fake: token streaming through your own server route, stop/regenerate, resume-on-reload, real markdown and code blocks, and correct mobile behavior.

Schema-Driven UI: Rendering Model Output as Components

Make the model emit data your components can render, and stream it: Zod schemas, constrained JSON, partial-object streaming into progressively-rendering components, and a bounded repair loop.

Prompts as Versioned Source

Treat prompts as first-class, reviewable artifacts in the app repo, not strings buried in a route handler: a typed registry, golden-file snapshot tests, version stamping, and a real timed rollback.

Token and ₹ Budgets Inside the Product

Cost control as product behavior, not a finance dashboard: pre-send token counting, context trimming, model-tier downgrade under pressure, a real usage meter, and a graceful hard-stop.

Ship It: Your First AI Feature in Production

Get Projects 3-6 onto a real public URL a stranger can use: free-tier deploy, server-side key handling, edge-vs-node runtime tradeoffs, verified streaming through the real CDN, and a proven secret-free client bundle.

Document Q&A as a Product

A real upload-to-answer product surface: per-file progress and failure, pgvector ingestion, inline citations that land on the exact source span, a designed refusal path, and per-user isolation.

Retrieval Quality You Can Defend

Stop guessing whether retrieval is good: a labelled question set, recall@k and MRR, and four controlled experiments (chunk size, hybrid search, reranking, query rewriting) each measured and costed.

Chat With Memory

A conversation system that survives 200 turns without blowing the budget: threads and messages in Postgres, editing and branching, rolling summarization, a deliberate token-eviction policy, and retrieval over past conversations.

Semantic Search as a First-Class Feature

A real search UI, not chat: facets, filters, typo tolerance, highlighting, keyboard navigation, and query understanding, measured against a keyword-only baseline.

Ingestion That Survives Real Files

Real files are hostile: layout-aware PDF parsing, DOCX/HTML support, OCR fallback, per-file actionable failures, content-hash dedupe, incremental re-index, and background jobs with real progress.
