I will build your saas web app with next js react and supabase


About this gig
I build web applications and SaaS platforms with Next.js,
TypeScript and Supabase.
I'm Even, a developer from Switzerland. A recent project is
24Steady, an AI chat product with Stripe subscriptions, a custom
onboarding flow, push notifications and an admin panel built
from scratch and running in production at 24steady.com.
STACK
Next.js, React, TypeScript, Supabase, Firebase, Stripe, OpenAI, Vercel
WHAT YOU GET
Clean, documented code that you fully own. Responsive across
devices. Authentication, database and API set up properly, not
patched together. Deployment included, so the app is live when
I hand it over.
WHAT I BUILD
SaaS platforms, custom CRM systems, admin dashboards, internal
tools, booking systems, marketplaces and landing pages. AI features
like chat, smart search or OpenAI integrations if you need them.
HOW I WORK
We define the scope together, I plan the build, and you get regular
updates while I work. You test before delivery. Timelines are agreed
upfront and I keep them.
I also build mobile apps with React Native, so if you need web and
mobile to work together, that's covered.

FAQ
Do you integrate real AI features into web apps?
Yes! I specialize in integrating OpenAI, ChatGPT APIs, and custom AI features. I was awarded for my AI assistant project at technical school.
What's included in the source code?
You get complete ownership of all code, documentation, and project files. Clean NextJS/TypeScript code that's easy to maintain and scale.
Can you work with my existing design?
Absolutely! I can work with your designs, Figma files, or create a fresh modern design from scratch.
What about support after delivery?
All packages include revisions during development. After delivery, I offer 30 days of free bug fixes.
How long does a project take?
Depends on complexity. Simple apps take 5-7 days, full SaaS platforms 14-21 days. I'll give you a clear timeline after we discuss requirements.
