  • imagen de RTjohn Rebuild web-scraper using SCRAPY + Data transformation - Long term project w/ monthly support $155.00 AUD

    “Yes, English is not his first language, but that was not the reason for our discord. I had requested to build a scraper, this gentleman agreed. One of the requirements was to scrape images, but I did not use the word 'download'. Yes, I 'changed' it - from scrape to 'download to filesystem'. Ok accepted. But then you do not even let me test the result of the full scrape and ask me incessantly to release the milestone based on a sample scrape? And guarantee support? No sir, no can do. On top of it, when you were running the code on my server, you stopped it and deleted it without my permission. You wasted my time and yours. When asked to show me where the requirements were not 'clean', you had no answer and cancelled​ the milestone.”
