Sehyo

A social network built around conversation instead of an algorithmic feed.

Full-stack · Product · Infrastructure

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.

Live product

Use the thing itself.
