Hi
I have created bots/automation software since the very beginning of Instagram. I have over 10 years experience and I have built so many scrapers for that platform over the years.
I can develop you a Windows Desktop Application that uses their mobile API where you can scrape from any niche to gather up specific information. Mobile numbers, e-mails, post counts, and anything else you need added to that.
I am an expert in this field, and I am confident I can create the best application to do this in regards to performance, efficiency, and I have all the knowledge of this platform when it comes to their security to help you avoid any road blocks they fire at you whilst you scrape.
Most developers here won't have much knowledge of Instagrams security (they don't like people scraping), but I do, and I can create the perfect software for it, and guide you all the way.
I'd love to help you out regarding this project, and I can do it in 1-2 days for ya.
