Hi,
What I understand from your project description is that you want a document, related to Agile & Software development edited, proof-read, and corrected. If that's the requirement, I bring immense value to you with my experience of 17+ years in technology & management. I possess all the skills you require for the project, including writing, agile, and software development. Let's chat more to set the correct expectations and plan out the delivery. Thanks!
