FinTech Mobile App — Development

Project Overview

We are looking for an experienced mobile app developer or small development team to help us build the of a new FinTech product.

This is a serious startup project, and we are looking for someone who can work carefully with financial functionality, security, APIs, and a modern mobile UI.

Important: Due to the confidential nature of the product, the public project description intentionally does not disclose the complete business model or proprietary financial mechanism. Detailed product specifications will be shared with the selected developer after an NDA/confidentiality agreement.

What We Need

We need a developer to build the technical foundation for a modern financial mobile application, including:

* Modern mobile UI/UX
* User registration and authentication
* Secure user profiles
* Financial account/wallet architecture
* Transaction interface
* Send/receive money functionality
* Transaction history
* Payment status tracking
* Notifications
* User verification/KYC integration readiness
* Secure API communication
* Backend integration
* Admin functionality
* Basic reporting and transaction management
* Error handling and security controls

The exact financial workflow and proprietary features will be provided privately.

Technology

We are open to recommendations, but the preferred architecture is:

* React Native or Flutter
* Secure backend API
* PostgreSQL/Supabase or equivalent
* REST/GraphQL APIs where appropriate
* Cloud-based infrastructure
* Strong authentication and authorization
* Modular architecture so the product can scale

Experience with financial APIs, payment providers, wallets, KYC/AML systems, or FinTech applications is a major advantage.

MVP Expectations

The first version should be:

* Fast
* Secure
* Scalable
* Professionally designed
* Easy to maintain
* Prepared for future payment-provider integrations

We are not looking for a simple UI prototype. We want a functional technical with a proper backend architecture.

Security

Because this is a financial product, security is extremely important.

The developer should understand:

* Authentication
* Authorization
* Encryption
* Secure API communication
* Sensitive-data handling
* Token/session security
* Fraud-prevention considerations
* Audit logs
* Secure database architecture

No real financial funds will be handled during the initial development/testing phase unless specifically agreed later through the appropriate licensed infrastructure.

Deliverables

The selected developer will be responsible for:

1. Mobile application
2. Backend/API foundation
3. Database architecture
4. Authentication system
5. Transaction infrastructure
6. Admin functionality
7. API integration framework
8. Testing and bug fixing
9. Deployment assistance
10. Technical documentation
11. Complete source code and project ownership

Confidentiality

This is an important requirement.

The complete product concept, financial mechanism, business model, and proprietary features will not be disclosed publicly.

Before receiving the full specification, the selected freelancer will be required to agree to appropriate confidentiality terms.

Please do not publish, reuse, demonstrate, or share any part of the project without written permission.

Who We Are Looking For

We prefer someone who:

* Has previous FinTech/payment experience
* Understands secure financial applications
* Has strong mobile development skills
* Can work independently
* Communicates clearly
* Writes maintainable code
* Can work with APIs and third-party financial services
* Is interested in a potentially long-term startup project

Experience is more important than having a large agency.

Project Scope

This is intended to be the first stage of a larger FinTech platform.

If the is successful, there will be opportunities for continued development, including additional financial services, integrations, automation, and expansion into additional markets.

Important

Please do not send a generic application.

When applying, briefly provide:

* 2–3 relevant FinTech/payment projects you have worked on
* Your preferred mobile technology
