Software we build and run

Ref Grid

Referee scheduling for sports assignors. Assignors manage officials and games; referees accept or decline assignments from a text or email.

Production work involved

• Email and password accounts with verification and password reset. Referees answer through single-use links and never need an account.
• Stripe subscriptions: Checkout, the customer portal, webhooks, trials and promo codes.
• Transactional email through Resend and text messages through Textbelt, with SMS usage metered per account.
• Cloudflare Workers with a D1 database and versioned schema migrations.
• An hourly scheduled job that sends due reminders.
• Sentry error tracking and rate limiting. Merging to main runs the test suite, applies database migrations, then deploys.

Developer tool · npm

PostPoint

Practice feedback and guidance for racquet sports players between sessions.

Production work involved
