Deploy & Configure Existing Financial App

I have an existing financial application called OneBox. The source code for the mobile app, web application, backend/API and database structure has already been developed.

I need an experienced developer to set up, configure and deploy the existing project, not redesign or rebuild it from scratch.

The work includes:

Deploy the existing OneBox web application to my domain/cPanel.
Set up the existing backend/API on my hosting/server.
Create and configure the PostgreSQL database from the supplied database schema.
Configure .env files and required server environment variables.
Connect the web application to the backend.
Configure the supplied Paystack test API integration and webhook.
Configure SSL/HTTPS and basic production security.
Install all required Node.js/npm dependencies.
Test registration, login, dashboard and existing application functions.
Configure the existing mobile application to communicate with the deployed API.
Build a test Android APK from the supplied mobile source code.
Provide the APK and make sure it installs successfully on an Android phone.

Important: The source code and README/instructions will be provided. This is mainly a deployment/configuration job. I am not asking for the application to be redesigned or rebuilt from scratch.

Any third-party services requiring production credentials will remain in test/sandbox mode until I provide the necessary credentials.

Please bid only if you have experience with Node.js/NestJS, React/React Native or Expo, PostgreSQL, cPanel/server deployment, REST APIs and Android APK builds.

Please give me a fixed price for the complete setup, not an hourly rate.

Deliverables: working web app on my domain, working backend/database, configured test integrations, working Android test APK, and a short explanation of the final server configuration.
