You will get a Node.js web app MVP with real-time features, built and deployed

Project details
We are a two-person studio: one designer, one full-stack engineer. That means you get an interface someone actually designed, and a backend written by someone who has spent about eight years on production systems.
We do not just build web apps for clients - we run our own. A multi-tenant PaaS, a real-time multiplayer service, an IoT smart-farm, a RAG AI tutor. All live, all operated by us. So the parts that usually go wrong after launch - deployment, sessions, real-time state, things breaking at 3am - are problems we have already had to solve for ourselves.
What that means for you:
• You see a live preview link early, not a surprise at the end.
• You get the full source, setup notes and deployment instructions. No lock-in.
• If it has to talk to a device or move in real time, that is the part we are strongest at.
Typical stack: Node.js, WebSocket, SQLite or Postgres, OAuth and 2FA, vanilla JS or Vite front-ends, Android via Kotlin or Capacitor.
Not sure how to scope it? Message me before you order. I would rather size the package correctly than deliver something that misses what you actually needed.

About Sooji
Web & App Studio: UX/UI Design + Full-Stack & Real-Time Dev
Hwaseong-si, South Korea - 12:08 pm local time
What we deliver:
- Web & app development — Node.js, WebSocket, real-time backends, multi-tenant SaaS/PaaS, OAuth/2FA, SQLite; Vanilla-JS/Vite front-ends; Android apps (Kotlin/Compose, Capacitor)
- UX/UI design — clean, conversion-focused interfaces and visual identity
- Hard engineering when you need it — our developer has ~8 years in embedded and robotics control (firmware, ESP32/Raspberry Pi, motion control, IoT), so we handle device-connected and real-time products most web teams can't.
We've designed, built, and now operate several live services ourselves — a multi-tenant PaaS, a RAG AI tutor, real-time multiplayer, an IoT smart-farm, and more — from planning through deployment and operation.
To keep it low-risk, we're happy to start with a small paid trial and milestone-based billing so you can verify quality before committing.
Tell us what you're building — we'll handle design and development together.
Steps for completing your project
After purchasing the project, send requirements so Sooji can start the project.
Delivery time starts when Sooji receives requirements from you.
Sooji works on your project following the steps below.
Revisions may occur after the delivery date.
Confirm scope and screens
I turn your description into a short screen list and data model, and confirm it with you. Anything ambiguous gets settled here, before I write code.
Build the front end
Responsive screens built to work on phone and desktop. You see a live preview link as soon as there is something to look at.
