Full-Stack Developer for Premium Fintech Platform

I am looking for an experienced full-stack web developer/team to build a complete, modern and premium financial platform called Investora.

The goal is to create a highly professional, trustworthy and mobile-responsive platform with a smooth user experience, secure account management, payment processing, portfolio tracking and a comprehensive admin panel.

Important: The business model and regulatory/compliance structure will be reviewed separately with appropriate professionals. The developer’s responsibility is primarily the technical design and implementation of the platform.

Core Features

2. User Dashboard

3. Payment System

* Payment gateway integration

Suggested Technology

Developer can suggest the final stack, but I am considering:

* Frontend: Next.js / React + TypeScript
* Backend: Node.js / Next.js API
* Database: PostgreSQL
* ORM: Prisma

* Deployment: Vercel/AWS or suitable alternative

I am open to better technology recommendations from an experienced developer.

Important Requirements

Please apply only if you have experience with fintech, payment platforms, dashboards, marketplaces or other applications involving sensitive financial/user data.

When applying, please provide:

1. Examples of similar projects you have built
2. Your recommended technology stack
3. Estimated development timeline
4. Fixed-price or milestone-based quotation
5. What will be included/excluded
6. Payment gateway experience
7. Security practices you follow
8. Whether you work individually or as a team

I prefer a milestone-based development approach, starting with UI/architecture and then progressing to backend, payments, dashboards, testing and deployment.

Please do not submit generic proposals. I want developers who have actually built complex web applications and can explain how they would approach this project.
