Development of an interactive web service (PWA) for a cultural project

Budget: 27000 UAH Deadline: 31 days

Hello!

I am ready to help with the development of an interactive PWA service for your cultural project. I have experience in creating mobile web interfaces, interactive logic, UX scenarios, and responsive web products.

For such a project, I would suggest the stack: React / Next.js, Node.js, an admin panel for content management, PWA, responsive layout, and maintaining view logic without repetitions.

Estimated timeline: 3–5 weeks after the specifications are agreed upon.
Budget: I will be able to provide a more accurate estimate after reviewing the full scope.

Good day! I have created web services that open from QR codes directly in the browser without installation — this is exactly PWA. The logic of "new material each time without repeats" will be implemented through a queue with a mark for already shown content, so it won't repeat until the entire set has been displayed. The stack is standard web plus a lightweight backend in Python; I will show examples of my work. How many units of content and types (audio/photo/text) do you plan? The volume will affect the timeline and budget.

Hello. I have been working with React/Node.js for over 9+ years. I am ready to collaborate.

Budget: 27000 UAH Deadline: 30 days

MVP benchmark - 120,000 UAH and 25-35 working days. I will provide more precise information after a brief project design within the marketplace, as the budget is heavily influenced by the admin panel, audio, analytics, and rules for reopening.

I would plan the stack - Next.js or Nuxt, server-side on Node.js, PostgreSQL database, media storage in S3-compatible storage, PWA layer for mobile experience. For such a project, it is important not just to layout the pages, but to properly establish the content model, user states, display history, and scenarios without repetitions.

We have experience in products that involve logic, role scenarios, and complex data presentation. Similar examples in essence:
> https://business.ingello.com/fractal - a product system with non-trivial interaction logic
> https://business.ingello.com/tts - a project with audio and automation of the multimedia process
> https://business.ingello.com/platforma - an example of a platform with architecture for development

From your side, we need materials or their structure, logo, and basic visual requirements, the desired user scenario after scanning the QR code, as well as a response - should content be added through the admin panel or is it sufficient to import via a table at the first stage.

I would like to clarify 2 things to avoid guessing:
> Is an admin panel needed for adding texts, audio, images, and links?
> Should the no-repetition algorithm work only within one device or is synchronization between user devices required?

Overall, this is a normal task for the team, but it is better to start with a brief architectural scheme and prototype; otherwise, a beautiful interface may quickly hit a weak display logic. A small saving at the start can easily turn into rework. Expand

Hello!

I have experience in developing modern web applications using React, Next.js, TypeScript, and Node.js, creating scalable backend solutions, integrating APIs, and implementing complex business logic.

For this project, I propose implementing it in the **PWA** format, which will ensure fast performance on mobile devices without the need to install an application.

Proposed stack:
* Frontend: Next.js (React, TypeScript);
* Backend: NestJS (Node.js);
* Database: PostgreSQL;
* Media storage: S3-compatible storage;
* Docker for deployment;
* PWA with caching support and fast loading.

The functionality can be built in such a way that:
* the user opens the service via a QR code;
* multimedia content (text, audio, images, links) is displayed without repetitions according to a specified algorithm;
* the administrator can manage content through a convenient panel without involving a developer;
* the architecture allows for easy addition of new content types and interaction scenarios in the future.

I preliminarily estimate:

MVP timeline: 4–6 weeks;
budget: from 2,000–4,000 USD (depends on detailed functionality, admin panel, and content delivery algorithm).

I am ready to discuss the details, propose the architecture, and break down the development into stages for transparent assessment and control of execution.

I look forward to collaborating! Expand

Four stages, each essentially a separate project, from cleaning the database to parsing new suppliers. The hardest part here is not the parsing itself, but the synchronization of stock and markup in two languages without duplicates and junk in the database.
I suggest starting with the first stage: updating stock and removing outdated products. This way, we can agree on the format using real data before scaling to the next stages.
I haven't worked directly with Opencart, but I'm familiar with the structure of parsers in Python and will figure it out quickly. Please tell me: how many suppliers are there now, and do they have an API, or just websites for parsing? And separately: how do products get back into Opencart? Through built-in import, direct connection to the database, or is there a ready-made API for the store itself?
The estimated assessment below is preliminary; I will clarify the terms and price after receiving answers to these questions.

PWA that opens via QR code and shows new multimedia content each time without repeats — clear.

Stack: Next.js (PWA via next-pwa, offline cache, manifest), content in Supabase or Firebase. The no-repeat algorithm — I store a session array of viewed IDs in localStorage, on the server Fisher-Yates shuffle with a restart after exhausting the pool. Audio via native Web Audio API or Howler.js. Admin panel for uploading content — simple CMS panel or headless Notion/Airtable as a source, depending on who will add materials.

Key point — the algorithm must account for anonymous users (without registration), so the state is stored on the client and not tied to an account.

How many content units are planned at the start and is analytics needed (how many times opened, which material was viewed)?

Ready to implement an interactive PWA web service with modern UX that will work via QR code without the need to install an application. For implementation, I propose the stack React / Next.js (Frontend), Node.js or Laravel (Backend), PostgreSQL/MySQL, with the possibility of further scaling. I will implement a content delivery algorithm without repetitions, an adaptive interface, fast performance on mobile devices, and a convenient content administration system.

Hello! The ideal UX for such a PWA is instant loading of audio/photos without delays and a clear operation of the "no repeats" algorithm.

I run the digital agency KenoStudio. My small team specializes in developing fast, custom web applications with a clean minimalist design free of visual noise.

Responses in essence:

Technologies: Frontend on Next.js (best for fast PWAs), Backend and database — Supabase. Media storage in Supabase buckets. The unique display algorithm is implemented through generating a temporary session_id or LocalStorage when scanning a QR code.

Examples and portfolio: We have experience creating interactive systems and logic (currently developing a custom habit tracker app). The quality of our UI/UX can be assessed on the projects Rationfit, Castoclub, and Kiss of Aroma.

I suggest a short 5-minute call to discuss the user flow and content delivery algorithm. Expand

Hello. An interactive PWA with a non-repeating algorithm is an interesting task, and here the logic of content display is more important than just the layout. I have done something similar: a landing page for a financial course on Next.js with Tailwind, where each section led to a form, and the conversion after the redesign increased from 2.1% to 4.7%. But in your case, the key is the mechanism for random selection without repeats, and this is no longer a landing page, but a full-fledged web service. To estimate the timeline and cost, I need to know one thing: is the content added manually or through an admin panel, and does it have a database? The first step is to outline the logic of material delivery in the form of a flowchart to agree on the algorithm.

Budget: 15000 UAH Deadline: 20 days

Hello.

Your project resembles a product with its own interaction logic more than a regular website. The main task here is not PWA, but the correct architecture of the content display algorithm, so that materials do not repeat, open quickly after scanning the QR code, and the system can be easily expanded.

For implementation, I would suggest Next.js, Node.js, PostgreSQL, and PWA. The viewing history can be stored locally or on the server depending on whether the user needs to receive the same sequence on different devices. If regular updates of materials are planned, I recommend immediately providing an easy admin panel so that the team can independently add texts, audio, images, and links.

The estimated budget for the MVP starts from 15,000 UAH. The exact estimate depends on the number of materials, the need for an admin panel, analytics, and the scenarios of the algorithm's operation.

The estimated implementation time is up to 3 weeks.

I can prepare a scheme for the non-repetitive content display algorithm for free or create a small interactive prototype of one scenario. If the proposed solution suits you, we will continue with full development.

I will provide examples of similar projects and a portfolio along with a brief description of the implemented logic, so that you can evaluate not only the design but also the technical approach. This will allow you to immediately understand how the work will be organized specifically for your project. Expand

In general, the task is clear, but to provide an accurate response regarding the deadlines and price, I would like to clarify some questions that arose after analyzing your task.

We already have a practically ready foundation for such a PWA service - it can be quickly adapted for a cultural project and launch the first working version ))

Estimated budget - from 85,000 UAH.
Estimated timeframe - 4-6 weeks, depending on the volume of content, design, and admin panel.

For technologies, I would suggest React or Next.js for the mobile interface, Node.js or Laravel for the server side, PostgreSQL for materials and display logic, plus a PWA layer for quick access via QR.
The algorithm is better to make with a history of views in the browser or on the server - then upon reopening or clicking, the user will receive new material without repeats.

Look, there’s a nuance - if the content is to be managed by the project team, it’s worth adding a small admin panel.
This will allow for self-updating texts, audio, images, and links without each edit going through the developer.

Relevant examples:
- https://business.ingello.com/fractal - similar in non-standard interactive logic and interaction scenarios
- https://business.ingello.com/vorfahr - an example of a service system with automation and thoughtful user logic
- https://systems-fl.ingello.com/ua - portfolio and working format of Ingello for Freelancehunt

I’d like to clarify 2 things to better estimate the cost:
- How many materials will there be at the start - 20, 100, 500+
- Is an admin panel needed for adding content, or can materials be uploaded once before launch?

We can discuss this now within the marketplace, I’m available.
From my feelings, the first MVP here can be kept simple - the main thing is to properly think through the content model, unique displays, and mobile experience, because the devil, as always, is not in the button, but in the states of the user =)

After brief responses, I will provide a more precise estimate by stages and propose a realization scheme. Expand
