Ultra-fluid communication and deadline met. I am very satisfied with the outcome of the project, Thomas delivered exactly what I asked for regarding my landing page, and even improved performance (loading time halved). He quickly grasped our database software to produce the feature we needed. I will work with him again in the future.
