I overheard some Able employees discussing Amazon's cloud services a few years ago in a food place at lunchtime. I walked over and started talking to the team.
Since then, I have been able to be a resource in many different ways.
For Able Aerospace, I was able to create a public facing website. It allows their customers to create a custom quote by collecting products.
For their job postings and the related workflow, I created a custom career center.
I have helped in the view layer on a Java Spring application they are developing. I also helped by prototyping the initial idea and assisting in the UI as the project progresses.
