Hey.
I have a degree in Business Administration and I have a master degree in Business Finance. I am currently working in the financial department of a technology company where I have been working for two and a half years; so I already accumulate some experience on tasks like billing, sending invoices and keeping in touch with customers.
My projects have been the following: Once I finished university, I worked for a bank, and after that I started with my current job, which consists basically in doing the tasks described with some other financial duties.
After finishing in the bank, I got a recommendation letter from the office director, which helped me finding other jobs.
Finally, about experience; I have been more than 2 and a half years dong administrative tasks. I contact with customers, register their orders and once they receive our services I send them the corresponding invoice and help them with possible issues they may find.
