Hello! Your project brief for the development of a restaurant order monitoring system is very specific and technically sound. I specialize in automating data collection and developing robust backend systems in Python/Docker (over 30 successful projects, including intensive parsing of SPAs and synchronization logic). I understand the criticality of a stable session for the restaurant business: orders should not be lost due to logouts or dynamic page updates.
🛠 My vision for technical implementation:
1. Parsing and Automation (Playwright):
* I will use Playwright (Python) in headless mode. It is faster than Selenium and works better with asynchronous loading (SPA).
* I will implement Request Interception logic: instead of just "scraping" the DOM tree, the script will intercept JSON responses from the site's internal API. This guarantees 100% data accuracy (prices, VAT, extras) without layout errors.
2. Multi-accounting and Parallelism:
* I will use asyncio in combination with a task manager. Each restaurant is a separate independent object (Worker) that has its own browser context (cookies/session).
* Adding accounts without restarting: I will implement this through periodic polling of the restaurants table in the database or monitoring a config file.
3. Reliability and Consistency (MySQL):
* I will use SQLAlchemy (Async Engine) to work with the database.
* Upsert logic (ON DUPLICATE KEY UPDATE): the system will identify orders by order_number + restaurant_id, updating the status (for example, "canceled"), but not creating duplicates.
4. API and Monitoring (FastAPI):
* A lightweight interface on FastAPI for managing processes.
* The /sync endpoint will trigger a background task to avoid blocking the API response.
📋 Development and delivery plan:
* Database architecture and Docker environment: Setting up containers (App + MySQL + Redis for queues, if needed).
* Authorization module: Stable login, handling redirects, and session persistence.
* Core parser: Logic for collecting the list of orders and details (Items/Extras/VAT).
* Synchronizer: Scaling to multiple restaurants and implementing the API.
* Testing: Checking "survivability" during internet or session failures.
⏱ Deadlines and cost:
* Execution time: 10–14 working days.
* Cost: $1,200 – $1,800 (depending on the complexity of the site structure and the number of nested pages for parsing extras).
Why me:
I have experience working with systems that require maintaining a session 24/7. My code will include Smart Retries and a logging system that will allow you to see the reason for the error (for example, change). Expand

Hello! I am ready to implement a microservice for order synchronization. The requirements for the stack (FastAPI + Playwright + SQLAlchemy + Docker) fully match my profile.

How I will ensure stability (according to your specifications):

1. Authorization: The script will save the storage_state (cookies/tokens) locally. Upon receiving a 401/403 error or redirect to login, the worker will automatically restart the authorization flow without crashing the entire service.
2. Multiprocessing: To handle multiple restaurants, I will use asyncio.gather with semaphores to avoid overloading the server with spawning browser tabs.
3. Data: The database structure (Orders, Items, Extras) will be implemented strictly according to the specifications. VAT and amount data will be validated before writing to MySQL.

The project will be wrapped in Docker, with automatic restart and logging (through the logging module to stdout for docker logs). I would be happy to explore test access.

Budget: 27000 UAH Deadline: 27 days

Hello.
For the last three years, I have worked on a project with a hypermarket and restaurant delivery.
I am a senior backend developer with ten years of experience:
- Python, MySQL (extensive experience), Docker (I know how to configure it), Git
- I have successfully used Playwright for various types of service parsers with protection
- I know how to implement multi-accounts, how to properly match them with a proxy system, and create proxy contexts.
- I understand how to properly synchronize data, not just copy/paste, but from the perspective of their architecture and the nuances of business logic.
- I have successfully applied both long polling and WebSockets as well as event-driven architecture approaches in projects.

I work with an hourly rate of $25-35.

Regarding the estimate:
The project description is not a complete technical specification.
From it, one can only provide a rough estimate - 80-140 hours.

The range depends on:
- how "crooked" the site is (SPA, anti-bot, WebSocket, etc.)
- the stability of the DOM
- the number of edge cases (cancellations, partial orders, etc.)

A precise estimate will be provided after creating a complete technical specification.
Thank you for your attention! Expand

Hello

I am ready to implement an order parsing service with synchronization in MySQL.

I have experience working with SPA (Playwright), authorization through sessions/cookies, and building stable parsers with Docker. I will implement: auto-login and re-authorization, order monitoring (polling/event), complete initial synchronization + upsert without duplicates, detailed parsing of orders/items/VAT. I will create an API (/sync, /status, /health), multi-account support (workers), logging, and auto-restart.

Stack: Python, Playwright, FastAPI, MySQL, Docker.

I am ready to discuss the details and start after gaining access to the test account.

Budget: 27000 UAH Deadline: 14 days

Hello! I can take on the development of a service that will log into the restaurant system's admin panel, track new orders, and synchronize them in MySQL in real-time.

What I will do in terms of functionality:

- Auto-login at startup and automatic re-authorization if the session is "kicked out" (we will see a redirect to the login page and log in again). Login/password only through env or config.
- Upon startup, I will perform a full synchronization of the history (today, yesterday, 7 days, 30 days), followed by constant monitoring of the Bestellungen page. New orders are immediately saved in the database.
- No duplicates: upsert by order_id, so that reprocessing updates the data instead of creating copies.
- Parsing both the list and the detailed order page: client, address, phone, comment, amount, payment (Bar/Online), source, type (delivery/pickup), status, items, extras, VAT by items, totals with breakdown.
- API for management: GET /sync, GET /status, GET /health.
- Support for multiple accounts (different restaurants) on one site: a separate worker for each restaurant, all data with restaurant_id. Adding a new account through config (if possible, I will implement hot-swapping without a full restart).
- Docker + docker-compose (MySQL in compose or connection to an external database), auto-restart, logs in stdout and to a file.
Deadline: 2 weeks.
Budget: 90,000 UAH fixed (or 3,500 UAH/hour, if hourly is more convenient).

To get started, I need access to the test account and a few screenshots/clarifications on where exactly the history switches (7/30 days) and whether there is pagination in the order list. Expand

Hello.

I propose the implementation of a separate sync service for this order system with a division into two layers: a browser-worker for authorization and navigation, and a sync-layer for saving changes in MySQL. This format provides stable re-authorization, a separate context for each restaurant, and proper control over repeated passes through the history.

From the screenshots, it is already clear that data will be collected in two stages: first, the list of orders, then a separate pass through the detail view with items, extras, and VAT. If internal XHR/JSON requests are available after login, it is advisable to use them as the main source of synchronization, leaving the DOM as a backup scenario. This simplifies service maintenance when interface changes occur.

I propose the following work plan:
1. Technical analysis of the test account and checking network requests after login
2. Building the worker with authorization, session control, and auto re-authorization
3. Initial synchronization of history and idempotent upsert in MySQL
4. Separate analysis of the detailed order page with items, extras, VAT, and statuses
5. API for manual sync, status, and health
6. Launch in Docker, logging, and configuration for multiple accounts

Before starting work, I need to clarify:
- Is it critical to add a new restaurant without a restart in the first version?
- What is the expected update frequency?
- Should we track the status change of already synchronized orders?
- How many accounts are planned at the start?

I am ready to begin with the technical analysis of the account and move on to the first working layer of synchronization. Expand

Hello.

I have extensive experience in developing similar services in Python, including browser automation through Playwright/Selenium, parsing dynamic interfaces, data synchronization in MySQL, working with Docker, and building APIs with FastAPI. I can implement authorization with re-authorization, full and incremental synchronization of orders without duplicates, support for multiple accounts, separate workers for each restaurant, and containerized launch through docker-compose.

I also have experience working with services where data needs to be reliably retrieved from SPA interfaces and carefully organized into a normalized database structure considering positions, add-ons, statuses, and change history. I suggest moving to private messages.

I am ready to promptly and qualitatively complete your order. I have experience working with similar projects, always adhere to deadlines and technical specifications. I will be happy to collaborate!

Budget: 14000 UAH Deadline: 6 days

Hello!

We consider your project a priority. We work in tandem: I (Nina) am responsible for management and communication, while the technical part is fully handled by a Backend specialist with extensive experience in automation.

We have thoroughly studied the technical specifications and the provided screenshots of the system (Orders, VAT, specifics of menu nesting). We understand that behind the external simplicity lies serious logic, which we are ready to implement "turnkey."

Why our solution will work reliably:

Working with sessions (Playwright): This is fundamental. We will set up the saving and auto-refreshing of auth_state (cookies/tokens) to avoid constant logins and bans. The bot will automatically restore the session when redirected to the login page.

Complex parsing (VAT and modifiers): We have taken into account the nesting of data (as in the example with Burger Menu + Extras). The entire composition of the order, including different VAT rates (7/19%) and sources (Lieferando, Uber Eats), will be correctly organized into MySQL tables.

Synchronization via Upsert: We will use SQLAlchemy to implement the "insert or update" logic. This guarantees the absence of duplicates and the relevance of statuses (for example, the transition of an order to Canceled).

Multi-accounting and Docker: The service will be designed on isolated asynchronous workers. Each restaurant is a separate process. Adding new locations will be done through the .env file without stopping the system.

Control and Healthcheck: We will implement FastAPI endpoints /sync, /status, and /health so that you can check uptime and synchronization statistics at any time.

We deliver clean, documented code in Docker containers. We are ready to discuss the details of access to the test account today and start working. Expand

My name is Dmytro, from King Kong Lab. We can implement a stable order parsing service with full synchronization in MySQL for you.
We have experience in developing similar systems: parsing SPA/dynamic websites using Playwright, working with sessions, automating authorization, data synchronization, and building services with API and Docker.
What we will implement:
- authorization with auto-reauthorization upon session loss
- real-time order monitoring (polling or event-based)
- complete initial synchronization (history) + upsert without duplicates
- detailed parsing of orders and items (including extras and VAT)
- support for multi-accounts (separate workers, restaurant_id)
- API (sync, status, health)
- fully containerized solution via docker-compose
- logging and auto-retries
On the stack:
- Python (Playwright)
- FastAPI
- MySQL
- Docker / docker-compose
We will make the architecture stable and scalable so that the service operates without failures even with a large number of orders.

Good day, I have experience in implementing similar services, write for more detailed discussion.

Budget: 2000 UAH Deadline: 2 days

Hello. The task is clear, I can implement such a service.

What I see for the solution:
— authorization and automatic re-authorization through Playwright
— monitoring the Bestellungen section with full initial synchronization of history (today / yesterday / 7 days / 30 days)
— parsing the list of orders and detailed pages
— saving in MySQL with upsert, without duplicates
— API for /sync, /status, /health
— support for multi-accounting linked to restaurant_id
— packaging in Docker / docker-compose
— configuration through env, logging, auto-restart

For the stack, I prefer Python + Playwright + FastAPI + SQLAlchemy + MySQL.

For an accurate estimate, I need to clarify:

is there test access
is this a SPA without a proper backend API, or can we partially work through network requests
how many accounts/restaurants are planned to be active simultaneously
is near real-time mode needed, for example polling every 5–10 seconds
should we track changes to existing orders, such as status changes

After clarifications, I will be able to provide timelines and costs.
If convenient, you can send a test account or a short video/screenshots of navigation through the orders!) Expand
