I will build mern stack saas mvp with ai features using vibe coding


Level 2
About this gig
Need a working SaaS MVP, or a new feature in your existing app, built fast and with code you can trust?
I build MERN stack web apps (MongoDB, Express or NestJS, React, Node.js, PostgreSQL when needed) using AI-assisted vibe coding with Cursor and Codex. I review, test and debug the code myself before delivery.
What I can build:
- SaaS MVPs with user accounts, dashboards and admin screens
- AI features inside your app, such as text summaries, draft replies or data extraction, using an AI provider you choose
- Stripe or PayPal payments and third-party API integrations
- New features or completion work on an existing MERN codebase
- Deployment to Vercel, AWS, DigitalOcean or similar
How it works:
- Share your idea, design or existing code
- We agree the screens, features and package
- I build with progress updates and deliver full source code with setup notes
Scope depends on your requirements and the package you choose. AI provider usage, hosting and third-party service fees are paid by you directly.
Please message me before ordering with your idea or existing app, so I can confirm the right package and timeline.
Regards, Nazar

FAQ
What does "AI vibe coding" mean — is the code AI-generated and unreliable?
No. AI tools like Cursor and Codex speed up development, but every feature is manually reviewed, tested, and debugged before delivery. You get production-quality code, just built faster.
Do I own the source code after delivery?
Yes. After the order is complete, the source code written for your project is yours, with comments. Third-party libraries and services remain under their own licenses.
Can you integrate payment gateways or third-party APIs?
Yes. Stripe or PayPal payments are included in the SaaS MVP and MVP with AI Feature packages and available as an extra for Single Feature. Other REST APIs count toward the number of APIs in your package.
Can you deploy and host the application for me?
Yes. Deployment to your own hosting account (for example Vercel, AWS or DigitalOcean) is included in the SaaS MVP and MVP with AI Feature packages and available as an extra for Single Feature. Hosting fees are paid by you directly to the provider.
What if I only have an idea, not a design or wireframe?
That's fine. Share your idea and main features, and I'll propose a simple page structure for your approval before development starts. Detailed UI design for larger projects may need a custom offer.
Can you add AI features to my existing app?
Yes, if it is a React and Node.js (MERN) app. Tell me the workflow you want, such as summarizing text or drafting replies. One AI feature fits the Single Feature package. You need your own AI provider account and pay its usage fees.
What counts as one screen or feature?
One page or one self-contained function, such as a login flow, a dashboard page or one AI action. Larger modules may count as more than one; I confirm this with you before you order.
Can you finish or fix my existing project?
Yes, for React and Node.js projects using MongoDB or PostgreSQL. I review the code first and tell you what fits your package. Heavily broken or very large projects may need a custom offer.
Will AI features always give correct results?
No AI model is always correct. I add error handling, test the feature with your example inputs and recommend human review for important or customer-facing results.
What if I need changes after delivery?
Small adjustments to delivered features within the agreed scope are included. New features or changes in scope need an extra or a custom offer.
