Hi Sir/Madam,
I have been working at Office 365 for 7 years. I have experience in Sharepoint, Project, PowerApps, Flow, Teams, Planner and PowerBI. I worked with Sharepoint Online and On-premise( 2010, 2013, 2016, 2019).
I developed three mobile/tablet apps using PowerApps with Flow like Inspection Management, Daily Worksheet App and Trade Monitoring App. I used many functionalities of PowerApps and Flow. I got the data from various sources; Sharepoint, Onedrive, Excel, SQL, Azure DB, etc. I developed a custom connector to get data from an external system that doesn't support from Flow. I can make a responsive form design. You can see some of the screens of my apps in the Freelancer portfolio.
Please let me know if you have any question.
