We already have live product containing HR, Finance and Project Management. We would like to integrate our new CRM requirement in to this existing PHP application.
Points to remember:
1. Understanding existing project is easy. An user can register a company, each company gets its own database. New CRM module contains features such as sales cycle management and email.
2. Existing module is developed is using simple code PHP. No framework is used. It doesn't contain any major defects but we will be more than happy to know them.
3. New CRM module need extensive understanding of Gmail API, Google Calendar API, MS Exchange API, IMAP, Office 365 API.
This project involves lot of modifications in the existing code, we already know that our existing code is not exactly the best work but we are looking for someone who can find us the solution, fix and work on it.
Bid if you are confident about two points. These are very important.
