The challenge
Repeated submissions must not create duplicate work. Invalid input and unavailable services need clear failure paths.
Selected work
VivaFreq: from a website request to a recorded next step
VivaFreq-owned system
Website inquiries are saved, sent to the person responsible and acknowledged to the visitor. Failed email deliveries can be retried.
Inspect the public example
The public form is available to inspect. Internal records and delivery controls are private. This case study describes the implementation, not a measured conversion or delivery-rate result.
View the inquiry formWhat we built
A TypeScript request handler validates input and records the inquiry, activity and notification jobs together in Cloudflare D1. Email delivery is handled separately through the Resend API.
Evidence and limits
Connecting a public form to durable storage and an email API, with explicit duplicate handling and tests for delivery failures.
