Helena provided the best quality of work I have experienced so far on Upwork. After a terrible experience with another freelancer, she was able to complete our project by the targeted date (which I thought was impossible - but she did it!). She was accommodating to all of our requests, super helpful in the development process, and extremely knowledgeable about the best way to meet our needs. I would highly recommend her and cannot wait for the chance to work with her again.
