Cryptocurrency Project: Full-Stack Developer Needed

I'm looking for a reliable full-stack developer to take over an existing cryptocurrency project.

The app is already developed, but it currently has bugs and unfinished functionality that need to be properly investigated and fixed. I need someone who can not only make changes but also test and verify that each task is actually working before considering it completed.

Main responsibilities

- Debug and fix existing issues in the application
- Upload and deploy the app to Google Play
- Develop and integrate new features
- Test every fix and feature thoroughly before marking the task as complete
- Investigate and address other development issues that may arise during the project
- Maintain and improve the existing codebase
- Communicate clearly and consistently about progress, problems, and estimated completion times

Required technical skills

- PHP
- Laravel
- Node.js
- Flutter
- React
- Vue.js
- MySQL
- API development and integration
- WebSocket / real-time functionality
- Google Play deployment

I'm particularly interested in someone who is honest, reliable, responsive, and a good communicator. I don't want someone who simply says an issue is fixed without properly testing it.

Experience or a genuine interest in cryptocurrency, blockchain, and crypto wallets is also very important, as this is a cryptocurrency project.

I'm looking for someone who wants to understand the project and contribute to it long-term, rather than someone who simply completes isolated tasks without taking responsibility for the result.
