Hi!
I have an experience in develop B2B and B2C applications. I know how to create a powerful tools for manage various attributes of business objects. I can also design a data model (DBMS) for a variety of complex systems.
Lately (from 2007) I like Python for its flexibilities and power.
In my opinion, Django entirely suited to create any online services: from simple API to a complete website. The built-in admin panel will help to reduce development time. Also, convenient built-in ORM, authentication, etc.
Flask is small but powerful framework for many tasks. My latest project was with using Flask: to develop a REST service for remote printing and scanning on Raspberry Pi.
My favorite DBMS is PostgreSQL. I use it since 2007 year. I like its built-in programming language (plpgsql, plpython) and good support.
I'm flexible with my working hours and am happy to work closely with any existing freelancers you work with.
Best wishes,
Gleb Mironov
