I am a software developer with an interest in open source. I entered open source community with pyexcel and continue to create more open software libraries and tools: moban, yehua etc. At the time of writing, I maintains 52 packages on pypi.

If your company has used any of my open source tools and its components into a revenue generating product, it makes commercial sense to support me to maintain my projects and develop them further.
