Hello,
I have been working with Python for about 6 years and I have used it for web-applications, home automation, data processing, system administration.
Regarding databases I have experience with design and tuning for PostgreSQL, MongoDB and MySQL.
On the web-frameworks side I've worked with Django but for recent projects I've only used Tornado due to its simplicity and performance.
I don't have experience with d3.js but I have used similar libraries like flot and dygraphs.
About numpy/pandas I've only done some reading mainly because for the projects I've done so far I preferred to create my own data structures using built-in types.
I also have experience with Linux, networking, GIS.
Best wishes,
Ionut
