Hi,
I have big experience in ETL (extract, transform, load) type of projects. I've been dealing with Salesforce for couple of years now and hold Developer 401 Certificate.
I'm familiar with the tools like Data import wizard and Apex data loader. I was also working on couple of advanced projects where I had to write custom Apex scripts that do the import for objects that hold relations to other objects (for example contacts, accounts with leads or cases). Also I was writing some scripts in PERL that do perform merging of couple of CSV (Excel) files based on some criteria so Import could be done easy.
Kind Regards,
Ilija Filipovic
