Development of an MVP online platform for interactive textbooks

Budget: 843 USD Deadline: 21 days

Good day!

I will be happy to collaborate, as I specialize in similar projects. I am a Full-stack developer and lead developer at Oria Agency, with over 4 years of commercial development experience. For the stack, I recommend choosing Next.js + PostgreSQL + pdf.js for the viewer module, Stripe for payments - this will be optimal for the MVP and easy to scale further. I have experience working with large projects, so there will be no difficulties in implementation; I would just like to know more precisely about the number of books at the start and the volume of interactive elements per page.

I will be happy to collaborate.
Sincerely,
Andriy Voznyak

Hello. Ready to help with the implementation.

I have experience in creating MVP applications. I developed a CRM for a tire fitting service (Admin part + cash register), for a jewelry business (admin part + cash register).
At the beginning, the main difficulties are determining the functionality, the expansion of which may be difficult to implement later due to architecture, so the first stage will be discussing all desired functions and identifying the main ones that will be in the first version.
The second difficulty is the projected traffic flow and optimization. For proper design, it is necessary to understand what scale you are planning (would like to have) in order to design optimization for the project.

I write on Next (React), Nest (Node), and for your project, I will use Postgres database.
All 3 running servers are hosted in Docker containers with a duplicate.

Implementation as I see it, we will have a call for a detailed discussion of the project, functionality, etc.

In 2-3 days, we can roughly outline what the frontend part will look like (roughly) with the help of AI we can talk about these terms.

After that, full development begins. As far as I see now, this may take 2-3 months.

My hourly rate is $16.

I can send more about past projects for your review in private messages. Expand

Good morning,

I have reviewed the assignment and I see a well-thought-out product here – an interactive learning platform with a PDF viewer, payment system, and admin panel is a project I know inside out.

MVP valuation: 18,000 – 24,000 PLN net, completion time: 8–10 weeks.

I implement similar platforms based on Next.js, Node.js, PostgreSQL, and pdf.js – a stack proven in educational and SaaS projects. I start with a solid architecture so that later development is fast and inexpensive, not the other way around.

I have implemented systems with an interactive reader, Stripe integration, and admin panels – you can see the projects at soft-synergy.com/portfolio.

I would be happy to schedule a short online meeting – this is not just a conversation, but a real consultation, after which you will receive a detailed report and a binding offer tailored to your project.

Good day, I am ready to implement a project on yii2 or laravel, there are many examples that can be viewed in the portfolio.

Budget: 4000 USD Deadline: 50 days

Hello! I have reviewed your project. This is a complex engineering task where the key aspects are not only the convenience of the reader but also the security of the content, resistance to loads, and flexibility in payment processing.

I propose:
Interactive Viewer: For rendering PDF, I suggest using pdf.js with a custom Overlay Layer on React. This will allow for precise positioning of hotspots (audio, video, zoom) based on coordinates over the page and ensure stable operation on mobile devices.

Security and content protection:
Account protection: Integration of Next Auth with mandatory two-factor authentication (2FA).

Rate Limiting: Protection of the API from brute force (password guessing) and attempts at automated content parsing.

PDF protection: Use of temporary links (Signed URLs) for access to files, which prevents direct downloading and distribution of content outside the platform.

Payment systems: Setting up a flexible gateway — not only Stripe for the international market but also integration of Ukrainian systems (MonoPay, LiqPay) for the convenience of local users.

SEO optimization: Full server-side rendering (SSR) for public pages and implementation of Schema.org microdata, so your books and landing pages rank high in search results.

Technology stack:
Frontend/Backend: Next.js (App Router)/Server Actions or API — the fastest solution for modern web platforms | Nestjs.

Database: PostgreSQL + Prisma ORM for reliable management of access and purchase history.

Infrastructure: Deployment on Vercel using Edge Network for minimal ping anywhere in the world.

Example of implementing complex Full-stack logic (dashboards, databases, security): recore-x66k.vercel.app

Preliminary estimate:
Budget: $4,500 – $7,000 (considering enhanced security and multiple payment gateways).
Timeline: 9–11 weeks to create a stable and secure MVP system.

I work as a Full-stack developer. Expand

Budget: 4800 USD Deadline: 50 days

Hello!

I understand well what you want to create: you already have books and media ready, and you need a convenient place where people can pay for access, open the book, and really comfortably learn right on the pages. I have already created platforms with paid access and custom readers based on PDF, and the biggest difference is always how stable the viewing works and how simple and reliable the access rules are.

For the MVP, I would choose a practical stack: Next.js for the entire web application, so the public part and the reader for authorized users live in one place, PostgreSQL for users, purchases, and book data, Stripe for payments, and pdf.js for displaying pages. On top of the PDF, I would add a layer of interactivity, where “hotspots” are stored in percentage coordinates, so audio buttons, video pop-ups, zoom fragments, and answer displays match exactly even on mobile.

One idea that could make the product special from day one is a quiet switch for “learning mode.” When it is turned on, the page is initially clean, and then the student clicks and opens the next interactive element in turn. This keeps the focus and makes the book feel like a guided lesson rather than an overloaded page with icons.

If a rough estimate is needed, an MVP with payments, accounts, a library of purchased books, a reader module, and a basic admin panel for uploading books and placing interactive zones usually takes 6–9 weeks. The budget depends on how many books you want to prepare for launch and how “smart” the zone editor should be, but most often such MVPs fall within the range of $4000–$6000.

Hello!

I have reviewed the task of developing an MVP platform for interactive textbooks. The project is ambitious and very interesting.

I fully understand that the key challenge here is not just a basic LMS, but specifically the integration of a PDF renderer with a custom overlay layer for interactive zones (hotspots), so that everything works smoothly, does not shift when scaling, and is easily configurable in the admin panel.

I will respond to your points:

1. Proposed technology stack:
The combination you mentioned would be ideal, as it will provide the necessary stability and scalability:

Frontend & Public part: Next.js (React) + TailwindCSS. This will provide excellent speed, SEO for the landing page, and ease of development for the personal account.

Interactive Viewer: Customized pdf.js + React wrapper for creating the overlay layer (Canvas or DOM elements with absolute positioning over the pages for audio, video pop-ups, and zoom).

Backend: Node.js (NestJS or Express) for the API.

Database: PostgreSQL.

Payment: Stripe (Payment Intents + Webhooks for instant and secure access to the books).

2. Experience and examples:
I have solid experience in developing complex web applications in JavaScript/TypeScript, creating personal accounts, and integrating third-party APIs.

I have worked with payment systems, database architecture, and complex frontend interfaces.

My works: https://github.com/AJoker0

https://ajoker0.github.io/titkov-portfolio/#blog

https://www.linkedin.com/in/andrii-titkov-dev/

3. Team:
I work independently as a Fullstack developer, covering both frontend and backend.

4. Estimation of timelines and budget (for MVP):

Timeline: Approximately 5–9 weeks of intensive work. The most resource-intensive stage will be the development and testing of the mapping mechanism (linking hotspots coordinates to PDF pages) and the viewer itself.

I will pay special attention to the visual editor in the admin panel during the MVP stage — so that it will be easy for you to "attach" audio and video to the necessary areas of the PDF pages without involving a programmer in the future.

I would be happy to discuss the architecture of the viewer in more detail. I am open to dialogue whenever it is convenient for you to chat or call? Expand

Budget: 3000 USD Deadline: 35 days

Hello! 👋📖
I have experience in creating educational platforms (LMS, interactive readers) with PDF viewers, payments, and admin panels. For example, I created a blog with comments/user accounts and a bot with interactive lessons — I can adapt it to your MVP with a focus on stability and scalability.

Team: me + one more Fullstack developer (2 people) to make everything beautiful and fast.
I will be able to implement a complete MVP: public part, accounts, payments, interactive PDF reader with hotspots (audio, video, zoom, hints, navigation) and a basic admin panel.

Proposed stack (optimal for MVP):

Frontend: React (fast interface, PDF.js with overlay for interactivity)
Backend: Django (API, authentication, admin panel)
Database: PostgreSQL (reliable for users/content)
Payments: Stripe (subscription/book purchases)
PDF viewer: pdf.js + custom overlay (audio, YouTube pop-up, zoom, buttons, transitions)
Additionally: Docker (deployment), Celery (asynchronous tasks)

Estimate: budget to be discussed (depending on the details of hotspots and PDF mapping), timeline 4–6 weeks (phased: public part → user account → reader → admin panel → tests).

I am ready to discuss the technical specifications, examples of work (portfolio), and start with a prototype in private.

Good day!

My name is Oleksii, and I represent the development team at The Dev Company. Your project is exactly the type of products we work with every day: educational platforms, LMS, and interactive content modules.

We have already implemented a commercial LMS project for an academy -> https://academy.defaust.com: account system, student cabinet, working with educational materials, basic admin panel, payments and access, gamification. You can register and test the platform – it is a live example of our development level. We also have experience with interactive viewer modules, overlay layers on top of content, and complex business logic for access.

How we envision the implementation of your MVP

- Public website + book pages + registration/login on React + Next.js (fast, SEO-friendly, easy to scale).
- Backend on Node.js (NestJS) with a clear modular architecture, REST/GraphQL API.
- PostgreSQL database (with ORM like Prisma/TypeORM for flexibility).
- Interactive PDF viewer based on pdf.js with a custom overlay: audio, YouTube pop-up, zoom area, “show answer,” transitions between pages.
- Payments through Stripe (or similar) with webhooks for automatic access to books/packages after payment.
- Basic admin panel for managing users, books, access, and interactive elements (hotspots).

The configuration of interactive zones (coordinates on the page, type of element, link to resource) will be stored in the database and edited through the admin panel – this will allow for quick addition of new books and interactive elements without developer involvement.

Timeline, budget, team

Based on your description, we estimate the development of the MVP within 12–16 weeks from start to production version. Estimated budget: 5,000 – 7,000 USD for the full cycle: from requirement clarification and design to deployment and basic testing. After a brief call/specification exchange, we will be able to provide a detailed estimate by stages and modules.

A small but experienced team will work on the project: Tech Lead, Frontend developer (React/Next.js), 2 Backend developers (Node.js, PostgreSQL), and a Project Manager for stable communication and a transparent process.

We are interested not just in making an MVP, but in building the foundation of a platform that can be scaled: adding new books, types of interactivity, roles (teachers, administrators), progress analytics, and other features.

This apparently requires a step-by-step logic for each book. A person reads the book in a strict order. The chapters of the book open in a certain sequence. And then, when they have gone through the entire book, they can access any chapter. At the same time, there are buttons on the page that trigger specific videos and audio. For implementation, bubble.io is an excellent fit. It is built on React and has an integrated database. Everything is in one package. And there, in the future, mobile native applications can also be created. The price depends on the number of books and their length.
