Testimonials

Ray (UpWork Client)
Joseph was exceptional in allowing us to work together to bounce ideas back and forth, to have us handle some of the tasks to help control costs. He spent enough time to understand the vision of the project and the users who would interact with it. With the COVID-19 problems, we were forced to put the project on hold, but we are sure to return and he will be an integral part of the product's continued development.
Amy (UpWork Client)
Joseph has developed a system that has transformed business. We have a very complicated internal system that needed a solution to ensure we executed all action items in our customer profile. His professionalism, organization, and knowledge of AppSheet is beyond reproach. He is extremely prompt with answers or solutions to any questions or problems I have. He is extremely creative in finding solutions to my any requests that I have. We will be using his services on a permanent basis.
Kelly (UpWork Client)
Joseph served as educator and resource on a tight timeframe. His availability and responsiveness was excellent.
Tomeka (Fiverr Client)
This is probably my third or fourth order and he has been extremely helpful and showed me every step that needed to be done. I will definitely be using greenflux again! Great customer service!
Paul
Can't believe how lucky I got finding Joseph! I've worked with many freelancers over the years, and a handful of mentors on codementor.io. Never have I worked with someone who has the knowledge, the ability to explain, the energy and enthusiasm, the creativity, and the preparedness all wrapped in one. What has stood out most to me, however, is his sincere dedication to my project despite the fact that he's "only" a contractor. Don't waste your time looking any further- if AppSheet is your platform, Joseph is your man.
