Hi,
although I enjoy a GREEN APPLE, I have a weakness for green grapes. That said...
### background
I am a professional certified engineer by Universidade de Sao Paulo, the most prestigious university in LATAM.
I have worked for IT companies and as an independent consultant for almost 18 years. During all that time I have been in charge of many RFIs and RFPs, acting both as customer and as service provider. That experience gave me a unique perspective on which kind of information and requirements can be requested in a real world. That is important because surreal demands tend to generate unrealistic promises.
I am also quite familiar with hardware requirements (sizing, integration, connections, etc...) as I have also been lead manager for a data center during almost 5 years.
I have been leading teams in charge of web portals and integrating them with payment gateways and ERPs (mostly SAP), for the last 10 years. I am familiar with all your requirements (login, security, databases, etc...)
Please feel free to contact me and you can assess my communication skills and professional experience.
Best regards,
Marcos Viterbo.
