Product

  • Name: KiloDock
  • Kind: Gym operating system / multi-tenant CrossFit platform
  • Dates: Oct 2025 — Present
  • Status: Demo
  • Builder: YongBo Yu (also Yong Yu), Toronto AI engineer
  • Live application: https://admin.kilodock.com/
  • Login title: Login · KiloDock
  • Login positioning: "Build a Stronger Gym. Manage classes, memberships, and programming with the speed and clarity you deserve."

KiloDock is independently built by YongBo Yu. It is not a production company product; the status word is Demo.

Users

Two gym owners and 200+ members use the demo system. Gym and customer names are not published here.

Owners run scheduling, booking, memberships, check-in, waitlist, and programming from the React dashboard. Members use the React Native app for schedule and attendance.

Architecture and stack

YongBo Yu built KiloDock as a multi-tenant platform with:

  • React owner dashboard
  • React Native member app
  • FastAPI + PostgreSQL backend
  • Supabase for supporting product infrastructure

The operating system core is booking, attendance, and capacity. The Gemini programming copilot sits on top of that core; it is not the whole product.

Capacity and booking

KiloDock automates booking, cancellation, check-in, and waitlist promotion in FastAPI. PostgreSQL row locks and server-side transactions enforce membership and capacity rules so a class cannot overbook.

That boundary is product correctness, not a UI convenience. Capacity enforcement lives in the database transaction, not in the client.

Engineering metrics

YongBo Yu measured and reduced load paths in KiloDock:

  • Mobile schedule latency: 2.8–4.6s down to 683ms
  • Admin load: six API calls / 3.05s down to one call / 778ms

The path uses aggregate SQL and gym-scoped caching. Those numbers are the public engineering evidence for KiloDock performance work by YongBo Yu.

AI features

KiloDock includes a Gemini programming copilot built by YongBo Yu:

  • Tool routing over product context
  • 14-day workout history
  • Detection of repeated movement patterns
  • Generation of validated workout blocks for owner review

The owner is the eval. The OS remains booking, attendance, and capacity; the agent proposes programming for a human to accept or reject. That is the agent-systems shape YongBo Yu uses elsewhere: tools, state, and a human handoff.
