What we build

Four crafts, one studio

Every product below is built on the same foundation: clean Flutter architecture, real-time reliability, and interfaces people actually enjoy using.

Live Streaming & Social

Real-time rooms, gifting, PK battles, voice/video seats and reels — built for scale with Agora, LiveKit and socket architectures.

Commerce

Catalog, cart, checkout and order flows with clean state management and smooth, native-feeling animations.

Wallets & Payments

Balances, top-ups, withdrawals and transaction histories, designed to feel instant and trustworthy.

Fitness

Tracking, plans and progress — approachable dashboards that make daily habits easy to keep.

Under the hood

Built with the same stack that powers real-time apps

Frontend in Flutter, backend wired for live traffic — sockets, streaming SDKs and cloud services that keep thousands of users connected at once.

What's running behind the live experience

A closer look at the systems that make streaming, chat and payouts feel instant.

Live rooms with Agora & LiveKit

Voice/video seats, PK battles and multi-guest rooms built on real-time SDKs, tuned for low latency at scale.

Socket.io event layer

A Node.js + Socket.io backend pushes gifts, reactions and room events to every viewer the instant they happen.

WebRTC media pipeline

Peer connections and signaling handled cleanly so streams stay smooth even on average mobile networks.

Firebase for the essentials

Auth, push notifications and lightweight realtime data, wired straight into Flutter with clean state management.

How we work

From idea to app store

A straightforward process, refined over 15+ shipped apps.

01

Discover

Understand the product, the users, and what "done" actually looks like before a single screen is designed.

02

Design

Wireframe the flows, then design an interface with a real point of view — not a generic template.

03

Build

Clean Flutter architecture, real-time systems where needed, and code written to be maintained, not just shipped.

04

Launch

Store listings, ASO basics and monetization set up so the app is ready for real users on day one.
