I have worked with Vtiger CRM for 5 years. I have good experience in both Vtiger open source and cloud version. I know the product in and out. I have worked on several vtiger extensions and integrations during my course of employment with vtiger. I can get work done faster.
Below are some of my work with Vtiger
1. Third party integrations with the product for Facebook messenger, Zoom meetings, Jio Meet, Wordpress, Microsoft Teams, Slack, Google Photos, Magento2, Xero Payments
2. Authentication using SAML(Security Assertion Markup Language) and Oauth2
3. Enabled few RESTApis for the product and contributed to development of ODATA to support Microsoft Power bi reporting.
4. Integrated product with various phone call providers like Twilio, Plivo and Telzio for click to call functionality.
