Website parsing

Hello, I can implement all 4 parsers according to the specifications and the provided reference.
I will configure the operation through a proxy, transfer the deduplication logic, implement hashing on the necessary fields, and build a complete data processing pipeline.
I have experience in developing complex parsers and data collection systems.

As a result, you will receive ready parsers with a unified logic of operation, stable data processing, and the possibility of further scaling.

After reviewing the specifications and the example code, I will be able to immediately assess the exact timelines and costs.

Please let me know what stack the reference code is written in and which specific websites need to be parsed?

Hello!

Excellent and technically sound technical specification. The presence of reference code is a huge plus, as we won't have to guess the desired deduplication logic; I will simply integrate your ready-made algorithm into the new architecture.

I specialize in complex web automation (Python) and building fault-tolerant data pipelines.

Many developers will provide you with 4 separate scripts, which will be very difficult and expensive to maintain in the future. I propose to assemble this as a single modular pipeline, where each site catalog is just a separate module connected to a common core.

How the architecture will be structured (Pipeline):
…
Collection and Proxy (Extractor): We set up proxy rotation with a retry mechanism. If the catalog times out or bans the IP, the script will not crash with an error but will gracefully switch the proxy and continue working from the same point. To protect against Cloudflare or JS rendering, I use Playwright; for fast sites, I use asynchronous Aiohttp.

Transformation (Transformer): Parsing the necessary fields and cleaning them from junk tags.

Hashing: We generate a unique composite key based on the 3 specified fields (MD5 or SHA-256).

Deduplication (Filter): I will transfer the logic from your reference code. I will implement hash checking "on the fly" (via generators) so that the script runs quickly and does not consume all the server's RAM when processing large catalogs.

Two clarifying questions:

Should deduplication work globally (looking for duplicates among all 4 sources) or isolated within each individual site?

In what format should the pipeline deliver the final cleaned data (CSV, JSON, or direct write to your database)?

I am waiting for links to the sites and your code example in private messages. I can start analyzing as soon as the details are agreed upon!

Good day!

Developing parsers with pipeline logic is our specialized area, so the task is completely clear. Having a technical specification and a code example is a big plus: we will maintain a consistent style and transfer your logic without deviations.

What we will implement:

4 parsers according to the technical specification for directory websites.
Integration of proxies (rotation + throttling for stable operation without blocks).
Deduplication logic — we will transfer it from your reference.
… Hashing on 3 fields for duplicate control.
Everything assembled into a single pipeline according to the described scheme.
To provide an accurate price and timeline right away, please clarify:

Are the 4 websites similar or different in complexity (JS rendering, anti-bot, authorization)?
Are the proxies yours or should we connect our own?
We will discuss the details in private.

I will create parsers with proxies and deduplication logic as a pipeline in Python. I have experience integrating hashing for data uniqueness and working with code examples. Can you clarify which specific fields need to be hashed for deduplication?

Hello. I can implement 4 parsers according to your specifications: I will rewrite the logic from the reference, set up proxies, add deduplication and hashing based on 3 fields, and also assemble everything into a single pipeline so that the data is processed sequentially and reliably. After reviewing the code example, I will clarify the details and propose the final architecture of the solution.

Good day! I specialize in parsing with Python and Java, have experience with proxy rotation, deduplication, and pipeline architecture. I will implement 4 parsers based on your code example — I will transfer the deduplication logic, add hashing for 3 fields, and connect proxies. The code will be clean, with logging and error handling. Before starting, I will clarify the list of websites and possible protections (Cloudflare, JS rendering). I will deliver on time.

Good day, I have created parsers for various websites. Code examples are not needed. I need the addresses of the websites, then I can provide a more accurate estimate of time and cost.

Hello!

I have extensive experience in developing solutions for parsing and processing data (various sources, protection against blocking, automation). I am ready to implement the assigned task in the shortest possible time.

I suggest discussing the details in private messages.

Hello.
I can develop a parser for you in the shortest possible time. Payment is hourly.
The number of hours needs to be approved in advance.
And it depends on which platforms/sites we are going to parse. Please send them to me in a private message.

The last project I worked on was a parser for foreign platforms (olx, vinted, jofogas), with monitoring and the logic you mentioned, but in the format of a Telegram bot. Reviews are in my profile or at the link https://freelancehunt.com/project/vosstanovlenie-podderzhka-dorabotka-telegram-bota-dlya/1592141.html

Feel free to write, I would be happy to do this for you.

Hello, I am interested in the project. I work with Python, web scraping, Requests/BeautifulSoup/Selenium, data processing, and saving results in CSV/Excel. I am ready to consider implementing 4 parsers for your websites with proxy integration, deduplication, and hashing on the required fields. I can also review the code example and transfer the necessary logic to a new pipeline. For an accurate estimate, I would like to familiarize myself with the technical specifications, the list of websites, a code example, and the format of the final data.

Hello!

I am ready to implement all 4 parsers according to the technical specifications. I can transfer and adapt the deduplication logic from the reference project, set up the work through proxies, implement hashing based on the specified fields, and assemble everything into a single pipeline.

If you provide the technical specifications and a sample code, I will be able to quickly assess the timeline and start working.

Bogdan, greetings.

I have reviewed your task. It's great when there is a ready-made specification and reference code, it immediately removes a lot of questions. I will write all 4 parsers in Python (Scrapy or BeautifulSoup, depending on how the sites provide the data).

I will set up the entire pipeline as needed: I will connect a proxy for stable collection, and I will simply implement the deduplication and hashing logic based on your example across three fields.

Please send me the links to the directories and your reference code in private messages. I will quickly review the structure and can immediately get to work.

Greetings! Excellent, clear task, completely within my profile. I will implement parsers as a reliable, fault-tolerant pipeline in Python (Scrapy/BeautifulSoup).

I will clearly transfer the logic of deduplication and hashing across 3 fields from your reference, and set up proxy rotation for uninterrupted operation. Since there is a ready-made technical specification and example code, I will do everything quickly and without unnecessary questions.

I am ready to start immediately after reviewing the reference. Let's discuss the details!

Hello, I have worked on parsing a catalog of over 50,000 products for an eCommerce platform, using proxy rotation and deduplication by hashes - this is definitely suitable for your 4 catalogs!

I’m curious about which specific catalogs need to be parsed and if there are any speed limitations for data collection?

I suggest we get in touch; I will provide you with free technical consultation and we can create a development plan + I will tell you about my team! ✨
