Transfer the online calculator page to the website and add payment for its use.

Budget: 10000 UAH Deadline: 30 days

I will implement a "seamless" integration of the calculator into the WordPress structure, hiding the technical elements of Streamlit and setting up an API gateway for data exchange between your Windows Server and the payment system.

Here are 5 technical steps on how I will solve your tasks:

Clean interface: I will use custom CSS injections for Streamlit to completely remove its menu, footer, and "squeeze" it between your header and footer in WordPress, creating the appearance of a single whole.

Payment logic (Payment Wall): Since the calculation should occur after payment, I will set up a "lock": pressing the red button blocks the script, generates a unique session in the database, and redirects to payment (with A/B promo code verification).

Control "2 attempts": Through the transfer of a session token, I will limit the possibility of recalculation: the server will allow the system to generate a PDF only twice for one payment ID, after which access will be closed.

Google Analytics: Since Streamlit operates in an iframe or through a subdomain, I will set up Cross-Domain Tracking so you can see the full customer journey: from entering the site to the moment of clicking the payment button.

Admin access: I will create a secure page on WordPress that will redirect you to the admin version of the calculator with automatic password transfer in the URL or through a separate authorization form.

I will assess the budget and exact timelines after a brief audit of your calculator's code — please write to me privately.

One important question: Is there a separate API endpoint implemented in your Python script on Windows Server (for example, through FastAPI or Flask) for remote data exchange, or is it currently functioning solely as a monolithic Streamlit service that handles both the front and back end?

Which payment gateway option (LiqPay, Stripe, or another) is a priority for you? Expand

Hello. I have experience with WordPress and Python. I am ready to help with integration.

Budget: 10000 UAH Deadline: 3 days

Alexey, it is important here not just to transfer the calculator, but to preserve the logic so that it works correctly on WordPress and opens only after payment. I would carefully integrate it into the site, linking payment and access verification, so that the user goes through the process without failures and unnecessary steps. I have experience with WordPress and service integrations, so I can immediately see where the risks may be. I can quickly analyze the technical specifications and propose a reliable solution.

Budget: 27000 UAH Deadline: 10 days

Good day!

I have reviewed the technical specifications. The task is clear: we need to transfer the existing Streamlit/Python calculator to the main WordPress site pro-kr.com.ua, integrate it into the site structure, add payment options, promo codes, and maintain the admin mode.

What I can implement:
– integration of the calculator into the WordPress site with a header and footer
– hiding unnecessary Streamlit elements
– access to the admin version via password
– connecting payment before performing the calculation
– promo codes: free calculation and a 15% discount
– logic for 2 recalculations after one payment
– ability to disable payment and keep the service free
– adding terms of service and privacy policy
– checking the functionality of PDF generation after transfer
– basic integration with Google Analytics / events

I envision the implementation in several stages:
1. Analysis of the current Streamlit application and the method of launching
2. Integration of the calculator into WordPress
3. Implementation of authorization for admin mode
4. Connecting payment and promo codes
5. Testing calculations, PDF, and payment scenarios

Estimated timeframe: 10–20 working days.
Estimated cost: from $1200, depending on the payment system and the current code structure.

For an accurate assessment, we need to look at the calculator code, the method of PDF generation, and determine which payment system we will use. Expand

Good day. I can take on such a task. I have experience in transferring and refining web services, integrating non-standard functionality into existing websites, working with Python backend, payment scenarios, access management, PDF generation, and logic with usage restrictions for the service. In your case, I see the task comprehensively: to carefully embed the calculator into the main website without the feeling of a separate streamlit application, secure the administrative part with a password, implement payment with promo codes and the necessary logic for repeated calculations, as well as add legal pages regarding terms of use and personal data. I can also suggest how to better organize this technically so that the service is convenient to maintain in the future. Please write in private messages, and we will discuss the details.

We have thoroughly studied your technical specifications for transferring the online calculator from calc.pro-kr.com.ua to the site pro-kr.com.ua. We are ready to implement the integration of a Python/Streamlit backend with WordPress, adding a full payment system with promo codes, password protection for the admin panel, and design adaptation (header/footer) with the hiding of technical elements of Streamlit.

We will also implement the logic for recalculating with different loads, the ability to switch to a free mode, and we will add pages with the terms of service and legal information about the engineer's liability.

We would be happy to help automate your engineering consultations and set up the service turn-key.

Hello!
I reviewed your technical specification.
The calculator form seems simple.
Therefore, it is better to create a new form on WordPress, and instead of a Python form, write an API, rather than inventing integration through proxy_pass or iframe.
It is unclear about the admin panel; the URL opens the same form but without contact details.
The task is not complicated, but it is time-consuming.

I see that you already have a working AI foundation calculator on a separate server, and it needs to be carefully integrated into the main WordPress site with the addition of paywall logic before use. I work with e-commerce integrations, payment systems, and embedding external services into CMS, so I can build a solution where the calculator works seamlessly on the WordPress page, and access to the calculation is granted only after payment. Technically, I see two approaches: either embed the calculator via iframe/API with token authorization after payment, or completely transfer the frontend to WordPress and leave the AI backend on the current server as an API. I will separately set up the payment integration: one-time payment for the calculation, package of calculations, or subscription — depending on your business model. The estimated timeframe is 7–12 working days, depending on the chosen approach, payment system, and complexity of transferring the logic. For an accurate estimate, please let me know: what stack the current calculator is running on, what monetization model is needed, and which payment system you are using or planning to use?

Hello!
I have experience integrating Python/Streamlit solutions into WordPress, as well as implementing paid services with access logic and PDF generation.

I understand your task: it is necessary not just to "insert a calculator," but to carefully integrate it into the site + add monetization and UX logic.

How I will implement it:

1. Integration of the calculator into WordPress
- I will transfer or wrap Streamlit as an embedded service (iframe / reverse proxy / API solution)

- I will set up access to the admin mode via password

2. Payment and access logic
- I will connect payment (LiqPay / Stripe - we will discuss)
- I will implement the scenario:
→ click "Calculate"
→ payment
→ opening the result
- logic "2 recalculations after payment"
- promo codes:
free access
15% discount
ability to disable payment (free mode)

3. Additionally
- PDF generation will continue to work correctly
- connection of Google Analytics
- pages: privacy policy + terms of use
- basic protection and stability of operation
- Terms: 5–8 days (including testing)
- Budget: 10,000 – 15,000 UAH
(depends on the method of integration and payment system) Expand
