PR review in Claude. Style, security, perf, tests — with file-by-file inline comments.

Terraform modules, state management, remote backends, multi-env workspaces, drift detection.

Production RAG — chunking, embeddings, hybrid search, reranking, caching, eval.

Production web scraping via Firecrawl. Handles JS sites, anti-bot, rate-limits.

Bun-native apps — bun.serve, sqlite-native, test runner, package manager, hot reload, single binary.

Server Actions done right — form mutations, optimistic UI, useOptimistic, revalidatePath/Tag.

Prisma schemas, migrations, relations, transactions, and the patterns that scale past 10k requests/min.

Next.js + tRPC + Prisma + NextAuth + Tailwind — end-to-end type safety from DB to UI.

Drizzle ORM — SQL-first TypeScript, schema, queries, migrations, edge-runtime compatible.

Idiomatic Go: goroutines done right, error handling, testing, modules, perf tuning.

FastAPI + Pydantic v2 + SQLAlchemy 2: async Python APIs with auto-generated OpenAPI docs.

Wire Firebase right — Auth, Firestore, Realtime DB, Crashlytics, Analytics, Cloud Messaging — via the BoM.

Pick the right Claude model per task — Fable 5 vs Opus 4.8 vs Sonnet 4.6 vs Haiku 4.5, with cost math.

Idiomatic structured concurrency: coroutines, Flow, channels, error handling, testing — done right.

Supabase + Next.js: auth, RLS policies, edge functions, storage, realtime — production patterns.

Wire Hilt dependency injection the right way — modules, scopes, ViewModels, WorkManager, testing.

Build edge-runtime APIs with Hono — routing, middleware, JWT, OpenAPI, runs on Workers/Bun/Deno.

Polars DataFrames — lazy evaluation, expressions, joins, window functions, the fast Pandas alternative.

Build autonomous agents on Fable 5 — Agent SDK wiring, memory, sub-agents, MCP, cost guardrails.
