Frank understood the requirements and gave me exactly what I needed. I would recommend him for Asterisk-oriented projects that require deep understanding.
I've worked with a lot of freelancers in my life with even over 15 and 20 years of experience but they never could solve the problem that Frank solved. I've never met in my whole life someone as smart as him. I'm so honored to meet such an amazing person who is so fast, so professional, words can't describe how happy I am while working with him. I trust only his work from now on, all my future projects are gonna be directly sent to him. He's a genius!
Frank is very professional. He knows the subject matter of my project very well. He shows an appreciated dedication to solve unexpected issues that come up. He is very flexible working on the project and adapting to the expectations. I am quite satisfied working with him and I will definitely work with him on similar projects. A big thank you Frank.
