Browser Automation Script for Dynamic Checkout Process

Hello! I suggest implementing this script in Node.js + Playwright instead of Python – this solution is significantly faster in headless mode, which will allow us to easily outpace the competition. I have extensive experience in JS and rapid DOM manipulation, so I will optimize the bot for minimal delays. Let me know if you already have a strategy for bypassing OLX anti-bot protections (proxy/captcha), or should I include that in the pricing?

Hello! I specialize in high-speed automation using Python and Playwright. I have experience in developing systems where the speed of response to DOM changes is a critical success factor.

How I will implement your task for OLX:

Choice of Playwright: Instead of Selenium, I will use Playwright. It operates through CDP (Chrome DevTools Protocol), which provides significantly faster response to the appearance of elements and eliminates the delays typical of Selenium architecture.

Maximum speed: I will configure request interception to block the loading of images, fonts, and analytics. This will allow the bot to "see" the button and the state of the page even before it is fully rendered in the window.

Lag resistance: I will use asynchronous locators with smart waiting (Auto-waiting) that respond to changes in the DOM instantly, without static delays (sleep).
…
Clean code: The bot will operate without a user interface (headless) or in standard Chrome, mimicking the actions of a real user to bypass basic anti-fraud systems.

My relevant experience: I have developed complex monitoring and rapid response systems based on Python (the Quant Traders project), where the response time to market anomalies was measured in milliseconds. I have a good understanding of the internal structure of the DOM and can write stable scripts for dynamic interfaces.

Okay Kamil

This is a very good explanation ; I would have to see what steps we need to go through visually

your budget is 255
this will take 3-4 days

I will also give you a what im going to go for step by step so you are not left wondering what im doing

… if you agree with the deadline ; you can dm me

Good day!

I am implementing on Playwright + Python — I have experience with OLX automation.

What I will do:

Detect the appearance of delivery elements through the DOM (without screenshots)
Automatic passage through all stages to the payment gateway
Minimal delay — reaction to state change is instantaneous
… Resilience to UI loading delays
Headless Chrome or regular browser — as needed

Hello! I will create a very fast script on Playwright (it is more efficient than Selenium due to native browser interaction).

What you will get:

Speed: Blocking the loading of media and styles for instant step progression.

Accuracy: Reaction to DOM changes in milliseconds through the locator system.

Stability: Handling dynamic elements and protection against detection (Stealth).
…
I have extensive experience in Python automation. Message me in the chat — we will discuss the logic of data passing, and I will get started.

Hello. I have been working with Playwright for 2 years and I can help you create a script that you will be able to easily edit yourself later. I actively work with n8n and I suggest making a script that can be easily maintained without having those skills.

Hello! I am Roman, an individual developer with 4 years of experience in creating automation systems and high-load scripts, so I will professionally fulfill your request for developing a bot for OLX based on Playwright, which will ensure maximum response speed to changes in the DOM tree and stable completion of all stages of the delivery process up to the payment moment; I specialize in asynchronous automation (Python + Asyncio), which allows for instant detection of the availability of logistics options and interaction with interface elements without the unnecessary delays typical of standard browser solutions, I work through a sole proprietorship and guarantee the creation of error-resistant code with minimal response time, and my technical solutions in process automation can be evaluated here: https://3magency.co/, https://jk-solution.com.ua/, https://farfieworldwide.com/, Behance.

Hi,
I can develop a high-performance automation script for OLX, optimized for maximum reaction speed and logistical process stability.
My approach to the implementation:
• Technology Stack: I recommend Python + Playwright. Playwright is significantly faster than Selenium as it communicates directly with the CDP protocol, allowing for reaction times of less than 1 second.
• State Detection: I will implement DOM-based listeners or intelligent polling to immediately detect shipping options without unnecessary page reloads.
• Speed & Latency: The script will run in headless mode with resource interception (blocking heavy images and trackers) to minimize interaction latency.
• Resilience: Using "Smart Waits" instead of static sleep commands ensures the bot progresses to the payment gateway the millisecond the UI is ready.
I have extensive experience in building high-frequency bots and real-time monitoring systems where every millisecond counts.

Hello!
I propose to create a Chrome extension for the implementation of your project.
I am waiting for a response, like a nightingale - flying!

Hi,

I’m Jeo. I have 8+ years of experience in automation, browser scripting, and high-speed workflow bots.

I recommend building this with Playwright instead of Selenium for faster execution, better event handling, and stronger DOM-waiting logic.

The bot will monitor specific DOM changes in real time, detect when the shipping option becomes available, and trigger the next actions immediately.

I will implement smart wait strategies, retry logic, and resilient selectors to handle UI delays and dynamic loading without breaking the flow.
…
The script can run headless for maximum speed and reduced latency.

Ready to discuss the exact flow and optimize it for the fastest possible execution.

Thank you

Hello.

I looked at the task — in general, it is clear what needs to be done. Such scenarios usually depend not on clicks, but on correctly tracking the state of the page (when elements appear with a delay or change).

I will do it using normal waits for the DOM without hacks like sleep, so that the bot reliably goes through all the steps to the payment gateway. I will take into account the moments with asynchronous loading and possible changes in the interface.

If speed is important — it can be implemented in Playwright, as it usually works faster and more reliably than Selenium for such tasks.

Regarding deadlines: 2–4 days for a working version.
…
If there are nuances in the scenario (different delivery options or page behavior) — it is better to discuss them right away.

Good evening. I will create a script as quickly as possible. Instead of slow Selenium, I will use Playwright — it works directly through CDP, which provides an instant response to changes in the DOM.

Hello

Recently built a similar OLX automation script( https://freelancehunt.com/project/pereglyad-profilyu/1607600.html ) - Playwright, DOM-based state detection, event-driven waits instead of sleeps for minimal latency.
One important thing upfront: OLX actively detects automation, so residential proxies are essentially required for stable operation - is that something you're ready to budget for separately?

Also, how many parallel processes do you need to support?

Hello!
I can implement the script. I will set up the work through the DOM, taking into account dynamic content, element expectations, and minimal delays for maximum speed and stability. I have experience in similar automation and working with web interfaces.

As a result, you will receive an optimized script that correctly responds to the appearance of the required elements, works without failures at different loading speeds, and quickly executes the scenario.

Please let me know if authorization in the account is needed and if support for multiple sessions/accounts is required?

Hello, Kamil. I have analyzed the task. The key trigger of your technical specification is the speed of operation on OLX ("faster than competitors").

Standard Selenium will lose here. My architecture for your task:

Engine: Python + Playwright (asynchronous mode).

Extreme acceleration: Setting up network request interception. The script will block the loading of images, CSS, fonts, and metrics. The DOM tree will load in milliseconds, which will provide a critical advantage in the speed of order processing.

Element search: Strictly through DOM locators (without visual rendering), which guarantees stability when the interface changes.
…
I work through Safe. I am ready to discuss the details of the logic right now.

Hello Kamil,
OLX occasionally deploys bot-detection measures (Cloudflare, CAPTCHA). If these are present on your specific flow, I'll flag it immediately and we can discuss mitigation options — I won't silently hit a wall and waste your time.
Ready to start as soon as you confirm the details. Can you share whether the flow requires login, and roughly how many steps exist between the listing page and the payment gateway?
