FileMaker Developer for Property Management Windows/Mac/iOS SDK

Andrii is very detailed and attentive. He has a great way of understanding not only the way something DOES work, but also the way it SHOULD work. And not just from the perspective of the technology, but also the way things should work for the end users. I would hire Andrii for any project in the future.

From FMP6 to the online world

Andrii pushed us along our journey from FMP6 to the online world at lightning speed. Without his technical powess, his language skills, his speed and dedication and without his friendly and helpful demeanour we’d be nowhere with our projec.

Need help on my FileMaker Pro 16 Homegrown budgeting/checking app

Andrew always kept me informed as to what he would do. He then documented what he did using screen prints that he marked up showing various info. He went the extra mile and added a few things that enhanced my app. Andrew completed the job in a very timely fashion exceeding all my expectations! What impressed me the most was his helpfulness even before I committed to selecting him as the freelancer. I was so thrilled with the results and will definitely call upon Andrew in the future.
