Parsing data from bulletin boards

The worst experience in 15+ years of working with freelancers.
Total rudeness.
Perhaps if you are a well-versed technical specialist with a full understanding of the process (API, databases, servers, proxies, etc.), it would be comfortable for you to work with Elena.

But if you are not technically very skilled (not mid-level+), be prepared for some unpleasant situations.
If you:
- want to suggest a solution to the problem, be ready to receive a sarcastic response "Great idea. Contact OLX support, maybe their programmers are listening to your optimization advice";
- do not respond on weekends, then you are deliberately delaying (unclear why);
- accidentally sent a slightly cropped screenshot - you are a falsifier;
- do not respond within 6 hours, then threats are made to close the project in its raw state due to lack of contact;
- you, 2 developers, and Chat GPT cannot find in the API documentation the list of all transmitted parameters - you are unprofessional.

Also, during the parser setup, Elena connected a database tariff on AWS that consumed over $250 in a week. Which looks like negligence.

Unfortunately, it was not possible to check all the work, because for any question instead of brief answers, the executor throws accusations. And for the time "spent" on writing these messages, she demands additional payment.

The task has been completed in full, but according to the client, he does not have sufficient competencies to test the project.
The technical specifications had gaps that I had to fill at the client's request.
The parser requires proxies, which the client was warned about before the start of the project. Proxies were provided, but they were of poor quality, and after 2 days they stopped working.
The parser cannot work correctly with non-working proxies.
To continue testing and implementing improvements, the developer's work needs to be paid for, which the client apparently is not ready for.
Overall, the work caused a strong sense of bewilderment — why order the development of a program that you then cannot use? A waste of budget funds.
