He made a video each time a portion of the project was complete to explain how it functioned and if there was any info he still needed from me to complete it.

"We hired Corben to help us with a dynamic shopping list that reflected the inventory in real-time at a busy food shelf in Vermont. We ended up with an easy-to-use system that works for our staff and volunteers. He's made a few updates along the way as our needs have changed. Almost 2 years later and we are still using it with great success. He's easy to work with and worked quickly to complete the job. Highly recommend!"
