GitDocs

Any GitHub repo → a polished, PR-ready README in about a minute.

Sign in with GitHub, point it at a repo, and a three-stage LLM pipeline reads the actual source, writes the README, hands you a split-pane editor, and ships the result as a single-commit pull request.

• SSE job stream, not polling

  Worker stage transitions travel Redis pub/sub → one EventSource per tab → pixels in ~50 ms. Refresh-safe and multi-tab safe.

• One atomic commit via the Git Data API

  blob → tree → commit → branch → PR. No "add file 1/2/3" commit spam — a clean diff a maintainer would actually merge.

• Images validated twice, stored nowhere

  MIME sniff client-side, magic-byte sniff server-side; screenshots travel browser → Node RAM → the repo itself. No S3, no orphans.

• Three storage layers, deliberately split

  Redis holds in-flight jobs, Postgres holds terminal state, GitHub holds the artifact. Each layer does the one thing it's best at.

PriceAlert

Market alerts you write in plain English.

"Ping me if BTC drops 5% in the next hour" — parsed into a validated condition object, watched every minute, delivered to Telegram and in-app with a grounded AI explanation of why it fired.

• NL → Zod-validated condition objects

  Relative moves, volatility windows, indicator crosses, compound conditions — things painful in a form, trivial in a sentence. The LLM parses; Zod is the law.

• Asset-agnostic engine

  BTC, gold, AAPL, USD/INR are just adapters. The watcher and evaluator never know what they're pricing — adding an asset class is one file.

• The watcher reads Redis, never Postgres

  Active alerts live in a Redis hot set; Neon is only written on create and fire, so it sleeps — the whole system runs on one ~$5 VM.

• Three trust boundaries on a public VM

  BFF calls carry user JWT + internal secret, Telegram's webhook carries its own secret, and nothing browser-facing touches Express directly.
