Yelena Druzenko

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.

Everything is excellent and very detailed. I recommend.

Just a wonderful performer, pointed out mistakes, added possibilities.

Olena is a great professional in her field, an expert in several programming languages, and it shows. Everything is excellent, the highest quality of execution! She exceeded expectations! I recommend!

The work was completed within the stated deadlines. I will cooperate and recommend!))
