FAQ
Can you do my university assignment or exam?
No. Asking for university assignments or any type of homework is against Fiverr's policy. I can only help with research projects that are part of a bachelor's, Master's or PhD thesis.
What is your workflow process?
1. Understanding Data and Requirements: extensive discussion to understand your needs. 2. Analysis Plan: formalization of the expected deliveries. 3. Project Execution: with constant communication along the process. 4. Delivery and Follow-up: ask as many questions as needed after delivery!
How can I feel comfortable that I will get what I actually need?
Before the order starts, I will make sure that we discuss your project extensively until you feel comfortable that I have understood what you need and I feel confident that I am able to meet your expectations. You may even request a video meeting if you want!
What if your delivey is entirely not what I expected to receive?
This has never happened before. However if for some reason the delivery is not what you expected, I will adjust the work as many times as needed until you are satisfied.
What if I've got the data but don't know where to start?
Don't worry. I have worked extensively with data science projects and would be able to help you designing your analysis plan.
Can you provide advise for my methodology?
Yes! Feel welcome to share your research goals and I can build an analysis plan for you.
