I would recommend to ask your manager to set priorities for tasks you got and review them on a regular basis:
1. You can create a Trello board with list for "new requests", "priority 1", "priority 2", "done", "others".
2. Tell anyone in your company who wants you to work on something or your help to go to that Trello board and add their request as a card to list "new requests".
3. Ask your manager to review all requests/cards in list "new requests" and sort them out for you – move them either to "priority 1" list, "priority 2" or to "others" list.
4. You work on requests in "priority 1" list. If you got spare capacity you can do requests from "priority 2" or "others".
5. When you finish with a request/card, move it to the list "done".
6. If there are too many requests in "priority 1" you tell your manager.
7. Every week review all lists with your manager.
You can connect Trello with Slack to get online updates, discuss requests, etc.
