We have experience in developing CRM systems for public use and for companies.
Here's our latest project:
https://dooozen.io/
This is a Web Application and Chrome Extension that automates lead generation on LinkedIn. Dooozen is a sales automation tool that helps Sales managers, Recruiters, and all active LinkedIn users to effectively organize and reduce their daily routines.
In this project users can connect prospects on LinkedIn, send messages and follow-ups, perform other actions in auto-mode.
