One edge-native stack spans relational data in D1, object storage in R2, session state in KV and scheduled Workers AI jobs.
Sehyo
A social network built around conversation instead of an algorithmic feed.

Problem
Most social products optimize for feed consumption. Sehyo starts with prompts and conversation, then asks whether the entire product can be built as an edge-native application without a traditional server stack.
What I built
I owned the product end to end: SvelteKit UI and state, authentication and guest sessions, relational data in D1, object storage in R2, session data in KV, scheduled Workers AI jobs, deployment, and browser-side encrypted messaging.
Evidence
OAuth and guest sessions coexist in the same product.
Direct messages are encrypted in the browser before storage.
