I was a bit crazy...

This is the story of how I become a:

• Developer
• Marketing Person
• Project Manager
   

For FREE!

Start with a Good Idea...?

I think it's a good idea

• Scikit-learn have similar methods for they models
   
• Have attempted to perform stacking form scretch
   
• Can I make it easier?
   
• Like Keras to TensorFlow

Footnote on stacking

Stacking is an ensemble learning technique that combines multiple classification or regression models via a meta-classifier or a meta-regressor.

The base level models are trained based on a complete training set, then the meta-model is trained on the outputs of the base level model as features.

I want it to...

• be on PyPI, which means people can pip install it
   
• have CICD test on GitHub, using Travis (now also so coverage by using a script)
   
• well documented, using read the doc
   
• easiest way, cookiecutter for the win

I become a developer... for FREE

Testing is as important as coding...

• TDD... at least I tried
   
• 99% coverage of testing
   
• More testing than code
   
• Make sure test are well named

Documentation is as important as coding...

• Docstrings are a must
  (helpful to people coding on a plane)
   
• Comments are also needed
   
• More documentation (docstrings plus comments) than code
   
• Also examples in read the doc and quick start quide

Good code itself is also important...

• Refactoring many times to make it well structured
   
• No ugly patching is allowed
   
• People will see you code (open-source)
   
• follow PEP8... at least I tried

I do marketing... for FREE

I need more noise!

• Tell all my friends (social media)
   
• Give lightning talks (elevator pitch)
   
• Get a logo, make stickers and give it to people (I have some with me btw)
   
• Recruit contributor via sprints
   
• Hacktoberfest!

It really works!

TODO

• More online presence (Medium post)
   
• Even more online presence (talks and tutorials)
   
• Community (slack?)
   
• A network of contributors via mentorship program

I manage project... for FREE

Managing a project is harder than contributing to a project

• Make it easy and obvious for others in issues
   
• Lot's of communication and reviews
   
• Be organized and prioritize (project boards)
   
• Encouraging people and acknowledge free labour (AUTHORS.rst)
   
• Lot's of LOVE 💕

But it is rewarding!

What I got...

• Learn a lot in software development in practice
   
• Made a lot of friends (my enthusiastic contributors!)
   
• Be inspired 💡
   
• Feel good about myself 🤗
