Switched from Travis to @circleci, build triggers much faster. Also switched from coveralls to @codecov, the UI is much better.

Got my first #opensource pull request merged. Can't wait that the package gets build and uploaded to #hackage. #codecov-haskell

👋 Have you noticed that @codecov now annotates a pull request on @github when you forgot to write tests for production code? ❤️ Very nice! https://t.co/jSKMC1C57y https://t.co/EGsqdVBbeY

@liran_tal
it amazes me how far opensource has advanced a package that serves thousands of users is adhering to code coverage thresholds (@codecov), has continuous integration safety net (@travisci), and ensures no security vulnerabilities introduced to the project (@snyksec) 🌈✨ https://t.co/ZDh7yUusLV

. @codecov is amazing; I've been integrating it into @databricks' open-source Scala projects and it's been a smooth process so far.
