•Services for Real Estate Agents: To pull data from various websites and cross-referenced those leads with provided materials from clients for a number of occasions on a weekly/daily/bi-weekly/monthly basis.
•Data Mining/Data Extracting/Lead Generation: For Lead generation purpose, data has been fetched from various records/inventory/archives provided by the clients. Sometimes, I have been asked to gather PTA information or donor information/race coordinator (for the charity of disabled persons) for the purpose of fundraising events.
•Web Research: To verify the newly found leads from those archives, I had to do some deep web research those via the secretary of state’s site or from BBB and google.
•Data insert into various CRM software: I had been always asked to do this task for real estate clients so that those new leads can be kept on CRM like vtiger, Zoho for marketing campaign purpose.
•Customer Support: providing mailing support for clients to their potential customers, setting up appointment schedule, following up with the prospects.
•Administrative task:
