Hello, I’m

Tedy
Fazrin.

I build apps for web, mobile, and desktop.

Most of my recent work is on communication products: chat, calls, and the state behind them.

I mostly use React, React Native, and TypeScript. I also work on Rust SDK and Go service integrations.

01 / Team projects

Selected work.

These are products I’ve contributed to with a team. Each project explains what I worked on.

Trait

Mobile calls & workspaces

Calls that need to work beyond the chat screen.

I worked on mobile calling, workspace startup, and the connections between the app and its services.

BBGE

Desktop messaging & media

A clearer desktop experience for conversations and calls.

I redesigned messaging and login flows, then worked on call state, permissions, and screen sharing.

Ech0

Mobile messaging & SDK integration

Connecting the mobile app to its messaging SDK.

I built the Expo app foundation and connected chat history, attachments, device linking, and message actions to the Rust SDK.

02 / Projects of my own

Cutroom.

From a long recording to clips worth sharing.

I built an AI-assisted editor that finds highlights, lets creators refine captions and framing, and exports videos for social platforms.

Photobooth.

A photo booth that runs in your browser.

I built the camera flow, photo-strip layouts, and canvas editor, including stickers, backgrounds, and language selection.

03 / A bit about me

I like working
through the details.

I pay attention to what happens when a call drops or a screen is still showing an old message.

I work on the interface and follow the problem into native code or services when it needs attention there.
