The goal is to obtain a full-fledged backend with the ability to further expand functionality and integrate with various services.
As a basic administrative panel, OpenCart is planned to be used, and interaction with the frontend will be carried out through REST API.

Future plans (integrations):

Payment services (in perspective): it is desirable to leave the possibility of integration with Ukrainian payment systems LiqPay, WayForPay, Monobank, etc.
Notifications via Telegram: after creating an order or changing its status, messages should be sent:
- to the client in a Telegram bot (message format will be agreed upon additionally);
- to us - as sellers, in an internal Telegram channel.
Ability to send messages via email simultaneously.
It is necessary to implement a mechanism that allows flexible configuration or addition of message logic (via custom code or a conditional "plugin").

Main functionality:

Product catalog https://prnt.sc/luhdh1kJBWE- https://prnt.sc/oUlK6Yq-k-Ss
Detailed product page (may require some customization of fields in the admin panel) we see it approximately like this https://prnt.sc/WDUDLNLgtaWF
Product categories
Filtering by parameters: https://prnt.sc/GY5Gjg8pXcBm
- categories
- sizes
- colors
- manufacturers / materials (optional)
Keyword search: by name, description, and other parameters.
User registration and login:
- authorization via Telegram API is possible (ready to discuss details).
Order history: https://prnt.sc/2h1G6jyBKTy9
- initially only in the admin panel (for us);
- possibly later also for users.
Shopping cart https://prnt.sc/q0U7qSTGzEvQ
Checkout process:
- select delivery method
- payment (initially only cash on delivery)

Technical conditions:

Admin panel based on OpenCart.
All interaction with the frontend via API.
We will provide:
- hosting;
- domain;
- auxiliary services (or we will set everything up ourselves beforehand).

What is required from the contractor:

Deploy and configure OpenCart.
Configure API for interaction with the frontend (possibly through a plugin or minimal code).
Implement Telegram integration (via webhook, API, etc.).
It is desirable that the contractor can work with the code, not just install plugins, as part of the logic will be custom. In our opinion, this is a few hours of work for a technical person.

Additional:
We are a technical team but have not worked with OpenCart before. Building a similar admin panel from scratch ourselves makes no sense — it would be a waste of time and money, so we decided to use a ready-made solution.

Request:
If interested, please respond immediately:

with clarifying questions;
or with an initial estimate of cost and completion time.

We understand that additional tasks may appear during the process — they will, of course, be paid separately.

Regarding the screenshots I sent (this is just to understand the structure, the admin panel appearance remains the same as in

OpenCart)

Update #1 from 4 July 2025

Additional explanation regarding API and integration approach

It is important for us that at the first stage we simply see what API requests are already available in the standard OpenCart template. We do not want to complicate the task or create new rules; on the contrary, we are ready to adapt to existing mechanisms.

I plan to prepare a brief API documentation separately (what is expected on the frontend), but to avoid misunderstandings and unnecessary time expenditure on both sides, it will be easier if we start with an overview of the basic API.

Attached to the description are screenshots demonstrating the main scenarios:

product list
product details with parameters
filters
shopping cart

This is the main part — based on this, it will already be possible to understand what data the API should return.

The search function is more "for the future," but as with most standard APIs, it probably already includes requests with:

pagination
basic search by name and description

This will be sufficient for starting the MVP.

Which API endpoints do we need at the start:

getting the list of categories
getting the list of products
product details
adding to cart
changing product quantities in the cart
placing an order
registration / login

We may have missed some basic ones, and I will ask the team to describe them additionally, but this is the foundation.

There are no critical requirements for us; we will work with what OpenCart already provides "out of the box".
If some endpoints return more information, it is not a problem; it may be needed in the future.
If something does not return data, it is also not critical; we will think about how to simplify or bypass it.

Our goal is not to rewrite the admin panel, but to use a reliable, proven solution.
Therefore, we do not plan to create a custom backend. On the contrary, we want to:

use the basic functionality of OpenCart,
extend it only as needed (modules, plugins, additional components),
work through the standard or extended API.

We understand that even in the basic template, OpenCart already has ready-made requests; this is what we need to see first. Then we will formulate what exactly is missing and which extensions need to be added.
