I've implemented http://airflowing.com using Seaside as foundation and my own framework on top of it. It's horizontally scalable and its object database is ACID compliant. Airflowing is a SaaS for service companies. Having covered a wide diversity of problems I can help you to go really far.
I have a strong bias towards designing User Experiences that makes sense, Design Thinking and fast prototyping.
I can use a lots of hats, we can talk business, Customer Development, investing, SaaS as much as front-end and back-end technicalities.
