A real-time chat system built for college batches — launched as the founding product at MJCET (Class of '26). Groups, DMs, roles, presence, typing indicators, reactions, replies, edits, and read receipts, sharded across 7 Durable Object workers with a primary handling auth, payments, and routing. One person built, deployed, and operates the whole thing.

A PR can look correct on its own and still break three other repos. Single-repo review tools never catch it.

External Servers Used

Clones and indexes every repo in a GitHub org into a local SQLite database, then hands Claude Code the cross-repo context — shared types, matching symbols, import chains — needed to catch breaking changes a single-repo review would miss. Runs entirely on your machine; nothing is sent to an external server. Built as a 24-hour take-home assignment.

Every number above was measured from the actual system. No staging builds. No demo data.

Receipts, Not ClaimsHow every number above was actually measured

Real infrastructure

Every number comes from the actual deployed system — Cloudflare's dashboards, npm, GitHub — not a staging environment or a demo build.

Publicly verifiable

BatchUp is live at batchup.fun. CodersEye's source and architecture decisions are public on GitHub. Nothing here asks you to take it on faith.

No cherry-picking

Figures reflect current, steady-state operation — not a best-case number from launch day.

Documented, not just claimed

CodersEye ships an Architecture.md and a LIMITATIONS.md alongside the code — including what doesn't work yet. Nothing gets hidden to look better.

Build time measured honestly

Counted from first commit to shipped and running — not from when the idea first came up.

Pages updated over time

As these keep running or shipping updates, this page reflects current state — not a launch-day snapshot.

Could This Be Yours?

Every product above started as a 15-minute call. If you've got something that needs to exist in production — not in a deck — that's the first step.
