Hello,
As discussed: Python + Sqlite => 1 category / sql , scrapy if web scraping will be needed
60 days free support with checks every few days to ensure script runs ok, any reasonable change free of charge.
I have done multiple projects involving Amazon but mostly with PHP. If you insist on using Python I can do it as well. I offer 30 days free support on my works, shall you want any changes done to the script they will be free of charge. Also in that 30 days time frame I will be checking in with you and if possible with the results of the script to ensure that it's working perfectly.
Contact me if you are interested in high quality works, communication and reliability... I've studied in US 7 years, I am great with research and understanding my client's needs. I go over requirements to obtain the best results time after time.
More about me... I have over 10 years experience in advanced data extraction, analysis and mining, including server administration [Linux, Solaris, FreeBSD], database creation, Excel works, web development [ PHP, Perl, Python etc ] I have studied 3 years towards my Mechanical & Aerospace Engineering degree at the University of Texas at Arlington and will be continuing starting next year when my immigration paperwork will get through.
I am eager to take your project and provided with clear and thorough specifications, I will certainly deliver the best results possible.
Thank you for your consideration,
Radu C
