Pratveders Platform Upgrade & Maintenance (Flutter + Node.js)
600 USDThe current project requires the improvements outlined in the presentation attached below.
To help you understand the existing system, here is a full architecture summary of the current project infrastructure and components:
1. Backend
Node.js server running on AWS EC2
Managed with PM2 (process restarts, uptime, logs)
Responsibilities:
API endpoints for the mobile app and web version
User session handling
Pack purchase validation
Communication with Firebase & Google Play Store when required
2. Mobile App
Built using Flutter
Currently deployed only on Google Play
Needs preparation for iOS App Store (Phase 1 or Phase 2)
Uses backend and/or Firebase depending on the feature
3. Frontend
Two separate React applications:
React Web App (pratveders.lv) — main landing page
React-based signup flow (pratveders.lv/pieteikties) — trivia signup form
Both are hosted under my domain and delivered via Cloudflare
4. Database & Storage
Using Firebase (Firestore + Cloud Storage) for:
Game pack data (images, answers, metadata)
Light analytics
Possibly some user progress for the “Profile” page
No additional databases are used
5. Cloudflare
Used for:
DNS management
CDN caching
Domain security (rate limiting, DDoS protection)
SSL certificates (if not handled elsewhere)
6. AWS
You will need access because:
The backend is hosted on EC2
PM2 configuration and logs live there
Backend deployments are performed on this server
7. Google Play Console
You will need at least Level 2 access for:
Uploading new Flutter builds
Managing internal testing tracks
Viewing crash logs / ANRs
Reviewing in-app purchase validation
8. GitHub Repository
Once you’re ready, I will share the latest repository containing:
Flutter mobile app
Node.js backend
React frontends
Game logic structure and current progress
9. Other Components
Nic.lv — domain registration only (no access needed)
Cloudflare — access required only if DNS or hosting changes are planned
Firebase — access required for database updates and improvements

I have extensive experience with Node.js and React, and I’m also somewhat familiar with Flutter. I’ve made many improvements to this project: https://familyoffer5.flclogin.com
.
At the initial stage, I will thoroughly review the backend and frontend source code in order to make optimal changes planned for phase 1.1, taking into account future deployment on iOS. Together with the mobile app source code, this will take about ten days.
Regarding the updates for phase 1.1 (it might also be possible to add trigger buttons to the “How to Play” page that open modal windows with screenshots of the pages referenced in the explanation), this work will take approximately one month.
I assure you that I will approach your project with a high level of responsibility.

1117 4 0 20 days2500 USDHi there!
I've read through all the details and I understand the full scope of your project. I can help upgrade and maintain your Pratveders platform across Flutter, Node.js, and React. For Phase 1.1, I would first ensure the mobile app is fully prepared for iOS while maintaining the current Android build, streamline API and Firebase interactions, and tidy up the React signup flow for smooth user experience. I can also optimize backend deployment with PM2 and AWS to avoid downtime, and make sure in-app purchase validation and analytics work consistently. One idea I can add is a lightweight live debug panel in the Flutter app for both platforms, so you can track user progress and crash logs in real time without digging through Firebase or Play Store consoles.
Estimated time for Phase 1.1: 18–20 days, covering iOS prep, backend stability, and frontend improvements.
Thank you!

I have worked extensively with Node.js, Flutter, React, Firebase, and AWS. I am experienced in maintaining and enhancing complex architectures, including backend APIs, mobile applications, and web frontends, while ensuring seamless integration with cloud services and platforms like Google Play Console.
For Phase 1.1, my approach will involve reviewing and optimizing the Node.js backend on AWS EC2, enhancing the Flutter mobile app and preparing it for iOS deployment, and improving the React web applications for performance and responsiveness. I will ensure that Firebase Firestore and Cloud Storage are used efficiently for game packs, analytics, and user progress, while maintaining stable deployments and monitoring. I will coordinate updates and testing across AWS, Firebase, and Google Play Console to ensure smooth releases and minimal disruption.
I confirm that I have fully read and understood the requirements, including backend, mobile, frontend, and cloud integrations, as well as the Figma design reference. I am confident in my ability to deliver high-quality, maintainable updates and enhancements to your project while ensuring clear communication and adherence to deadlines.
Thank you for considering my application. I look forward to the opportunity to contribute to your project.
…
Best regards,
