Multi-tenant workspaces
Each organization operates inside its own isolated workspace.
Live SaaS platform / Attendance & check-in
CheckStation
CheckStation is a multi-tenant SaaS platform for configurable check-in and attendance. Organizations run their own workspaces with Members, Groups, and self-service kiosks, while every action is preserved as historical attendance records.
Built for schools, workplaces, clubs, training organizations, and similar teams that need flexible participation tracking.
Overview
What CheckStation is about
What it is
CheckStation is a multi-tenant SaaS platform for configurable check-in and attendance. Organizations manage Members, Groups, staff access, and participant-facing kiosks inside their own isolated workspace.
Why it exists
Most attendance products are rigid and tied to a specific workflow or industry. CheckStation is designed so organizations can configure their own Groups, kiosk actions, and participant flows while retaining durable history, permissions, billing, and operational controls.
My role
I am the sole builder of CheckStation. I designed the product architecture and multi-tenant domain model, built the Django/DRF backend, React web platform, kiosk system, authentication, Stripe billing, localization, email infrastructure, and production deployment.
The live web platform is deployed across checkstation.app and workspace.checkstation.app. I am currently extending the same backend APIs into mobile and desktop applications.
Core features
What the platform covers
Owner & staff accounts
Owners manage the workspace while staff can access operational tools through separate credentials.
Members
Reusable people records can participate across Groups without needing dashboard accounts.
Groups
Groups define long-lived participation contexts and their associated kiosk behavior.
Self-service kiosks
Each Group can launch a participant-facing kiosk for check-in and related actions.
Kiosk editor
A visual editor lets workspace owners customize the kiosk appearance and flow.
Attendance history
Every kiosk action creates lasting historical records for activity, attendance, and reporting.
Plans & billing
Basic, Plus, and Business plans with entitlements, trial behavior, and Stripe subscription management.
Authentication & security
Email/password auth, Google and Apple sign-in, optional owner 2FA, rate limiting, CSRF protections, and tenant isolation.
Localization & email
English/Japanese UI plus platform and per-Group email delivery.
Product views

Public CheckStation site

What I built
End-to-end ownership
Product architecture
Designed and documented the multi-tenant SaaS architecture around Organizations, Members, Groups, kiosks, attendance records, billing, and isolated workspace access.
Backend & APIs
Built the Django + Django REST Framework backend powering workspace operations, kiosk actions, authentication, billing, content, and tenant-aware APIs.
Web platform
Built the React + Vite public marketing site and authenticated workspace application using custom CSS and responsive layouts.
Groups / Members / Kiosks
Implemented the core participation model, including reusable Members, Groups, configurable kiosk actions, participant-facing kiosk runtime, and durable history records.
Kiosk editor
Built the visual kiosk customization system so Groups can configure the participant check-in experience without turning the product into a generic form builder.
Authentication & security
Implemented owner/staff authentication, Google and Apple OAuth, email verification, optional owner TOTP 2FA, CSRF protections, rate limiting, Turnstile, and workspace isolation controls.
Billing & subscriptions
Built Stripe Checkout, webhook processing, Customer Portal flows, plan entitlements, upgrade/downgrade/cancel behavior, and the built-in 7-day Business trial.
Deployment & services
Deployed the live platform across CheckStation domains using Django/Gunicorn, PostgreSQL, Redis, Nginx, Cloudflare, Resend, and supporting production services.
