About this gig
Do you want to build an AI-powered SaaS Builder that creates full-stack websites and fullstack mobile apps in minutes through chat prompts?
I will develop your AI-powered SaaS builder (No Code / Low Code Builder) like Lovable, Bolt, and Emergent. And also include custom features based on your request.
After building a full-stack web application by chat, the user can make it publicly available with a preview domain and can also connect his own domain.
As like as web, user could create an Android and IOS app by chat and publish it to the Play Store and App Store.
You could integrate an image generator to create any kind of AI images and a video generator to create any kind of video with custom duration.
Integration & Technology:
- AI Agent and AI Workflow
- Deployment on AWS Cloud
- Payment Gateway, Mail provider & MCP integration
- Expo, Cloudflare, Supabase
- ReactJS, NextJS, TailwindCSS, NestJS, ExpressJS, NodeJS
Why me?
- I have 6+ years of full-stack web and app development experience with a lot of happy clients.
- I don't deliver until fully satisfied.
- I ensure a 100% refund if I can't meet the requirements.
Note: I am open to discussing any kind of custom requirement.

FAQ
What's the difference between the three packages?
Basic gives you a landing page builder: your users generate frontend pages by chat, no backend or database. Standard gives you a fullstack builder for either web or mobile, including deployment and app building. Premium gives you both web and mobile in one platform.
Does Basic include a backend or database?
No. Basic is frontend only, so the apps your users generate are static landing pages with no server, no database, and no user accounts. If your users need logins, data storage, or APIs, you need Standard or Premium.
In Standard, do I choose web or mobile?
Yes, you pick one at the start. Standard covers a fullstack website builder or a fullstack mobile app builder, not both. If you want your platform to do both, that's Premium.
Can I start with Basic or Standard and upgrade later?
Yes. I build on the same architecture at every tier, so upgrading is an extension rather than a rebuild. You pay the difference plus the added work, and nothing you already paid for gets thrown away.
What exactly will I get, a finished product or just a demo?
A fully working, production-ready platform deployed on your own cloud account, plus complete source code, database schema, and documentation. Nothing is locked or hidden. It's your product from day one.
Will my platform really work like Lovable or Bolt?
Yes. The core flow is the same: your users describe what they want in chat, the AI agent plans it, writes the code, runs it in a live preview, and lets them iterate through follow-up messages. Standard and Premium match that experience most closely.
Can my users really publish to the Play Store and App Store?
Yes, on Standard (mobile option) and Premium. Apps are built with Expo, so the platform produces real native builds for Android and iOS. Store submission still requires the user's own Apple Developer and Google Play accounts, and I set up the full build and submit pipeline.
Can you add features that aren't in the packages?
Yes, and most clients do. Image generation, video generation, custom AI agents, MCP integrations, admin dashboards, team workspaces, analytics, affiliate systems. Tell me what you have in mind, and I'll say honestly whether it's feasible and what it adds to the timeline.
How do my users get their projects online?
Every generated project gets an instant preview domain, and users can connect their own custom domain from the dashboard with automated DNS and SSL through Cloudflare. Deployment is included in Standard and Premium.
Do you provide support after delivery?
Yes. Every order includes a post-delivery support period for bug fixes and handover help, plus a walkthrough so your team knows how everything works. Ongoing maintenance is available as a separate monthly arrangement.
