Hello!
It is my understanding that you are looking for a scalable, secure, mobile-responsive business website for your new startup.
My main area of expertise is developing sites using Python with the Django web framework. This provides numerous security and scalability advantages for a business website, and it will be easy to modify the site later as your client base grows and your needs change.
This is how I would tackle your project:
1: Talk with you to refine and clarify your project requirements.
2: Design data models and user views (i.e a simple, functional version of the site without styling.)
3: Integrate the site with Twitter bootstrap, custom CSS, AJAX to suit the "look and feel" that you want for the project and add in mobile responsiveness.
I am a native English speaker with strong communication skills. Please contact me if you have any further questions!
Thank you for time and consideration!
-Chris
