Hello
All my family is from Madeira, and i am currently living in Venezuela, working to go to Spain next year.
I have been working from the past 5 years in the development of applications for financial institutions, automating their processes and risk methodologies.
One of the technologies used in those projects is php.
This makes me guarantee you i can program the complex algorithms you need in php.
Hope you like my proposal, and we can work together in your project.
Best regards
Hector De Sousa
