Hello, I have extensive experience in full-cycle development from creating specifications to publication.

Regarding the technology stack, there is a proposal to implement the mobile part using Flutter. In addition to simplicity and reliability, a plus will be the ease of maintenance and the number of offers in the market.
In addition to mobile applications, I suggest immediately implementing a web version. This will not cause an increase in budget but will add convenience for users.

I have experience in creating and supporting a B2B application for employee training.

Here is how I envision the development:
1. Basic backend + admin panel
… 2. Development of applications with API implementation on the backend side
3. Full implementation of the backend
4. Product debugging

This approach will allow you to quickly assess the functionality of the application and, if necessary, make adjustments without waiting for the completion of the backend development.

If necessary, I am ready to outline the timelines and stages of development in more detail. Payment after the work is completed.

Hi,

With over 7 years of experience as a Full Stack Developer, I have extensive experience building mobile applications using React Native/Expo, integrating backend services with Express.js and PostgreSQL, and implementing caching and session management with Redis. I am also skilled in automated testing (unit, E2E), API testing with Postman, load testing with k6, and monitoring application performance using Sentry and PostHog.

My approach will include developing the mobile app for both iOS and Android, integrating secure and scalable backend services, implementing subscription management, and ensuring smooth analytics and monitoring. I will also ensure that the user experience aligns with your Figma design while maintaining data privacy and security for all users.

I am happy to discuss alternative technology suggestions if needed to optimize performance, scalability, or maintainability. I can provide a detailed estimate of timelines and cost once I review the repository and project requirements more closely.

Thank you for considering my application. I look forward to the opportunity to collaborate and deliver a high-quality solution for your project.
…
Best regards,
Jeo Vincent Carretas

Hello,

My name is ASSONTSA SONFACK TOSCANI, and I am a mobile app developer with experience in building hybrid applications for both iOS and Android. I specialize in creating clean, responsive, and user-friendly apps that meet client specifications and deliver smooth performance.

I am confident in working with your tech stack (Express.js, PostgreSQL, Redis, Expo/React Native) and can also suggest improvements if needed. I pay attention to testing, monitoring, and analytics to ensure the app is reliable and scalable. I am ready to implement your Figma designs and turn them into a fully functional subscription-based app for anonymous school surveys.

I am enthusiastic about bringing this project to life, delivering a polished, user-centered application that works seamlessly for your target audience.

Best regards,

Hello, Aman!
Thank you for the detailed information.
I have read your document, thoroughly checked your design, and understood everything.
Here is a brief technical solution for creating a fully anonymous mobile application for conducting school surveys, exactly as described.
I will build the system based on Express.js + PostgreSQL + Redis for a scalable backend, using Redis for rate limiting, caching school lists, and limiting survey intervals (10 surveys / 40 minutes, a total of 120 surveys per day). The survey engine will use only templates generated by the administrator, ensuring strict anonymity, hashed identifiers, payload encryption, and data storage in accordance with GDPR. Expo (React Native) will provide builds for iOS/Android with built-in in-app purchase (IAP) features, a multilingual user interface, automatic layout when changing languages, and convenient navigation.
On mobile devices, subscriptions will be processed through App Store/Play Billing with receipt verification on the server side, ensuring compliance with access levels (free or paid). Push notifications will be sent via Expo Notifications with customizable channels for "new survey" events. Complaints will be sent through a secure API to the administrator's email, including survey metadata and the user-specified reason. I will integrate Sentry for logging failures/errors and PostHog for analytics (registration, survey responses, purchases, retention, navigation).
Security will be enhanced through Redis rate limits, JWT rotation, survey event encryption, anonymous analytics, and protection of minors' data. The final results will include unit tests for core logic, end-to-end flows for surveys + IAP, and load tests using k6 for parallelism. Deployment will be carried out according to your three-phase release plan (beta version - permissions - full IAP version).
I am confident that I can complete your project perfectly and on time.
I would like to discuss this with you.
… Thank you.
