I have a lot of experience in google apps script development:
Spreadsheet and document automation
GMail, google disk services
Calendar integration
Data management, cms
Export \ import, API, services and so on...
I make productive, optimal and well-structured code, with detailed comments.
My background based on strict programming language pascal, delphy, c++, assembler.
I'm a responsible and accurate coder.
I work without a rush, I'm sure that reliability and effective code is more important.
I can work in a team or alone.
