Well, I think the most important thing I can say about myself is that I love learning and I really love creating things.

And, as I can't stay away from writing the best code I'm able to, you can find me almost every day on [GitHub](https://github.com/lucasfcosta), contributing to open-source projects and also helping to translate and produce content for other developers.

I have already spoken at countless meetups and major events in Brazil such as Front In Poa, JSDay Recife, and The Developer's Conference Florianópolis and at international events such as Voxxed Days Bristol, O'Reilly's 2017 FluentConf and NebraskaJS 2017. Now that I've moved to the United Kingdom I expect to do even more talks all around the world :)

I've been one of [Chai.js](https://github.com/chaijs/chai) core maintainers since 2015. Chai is one of the most downloaded NodeJS modules and the most famous assertion-focused library around, with outstanding [4.2 million monthly downloads and lots of dependents](http://npm-stat.com/charts.html?package=chai). Being part of such a huge project has not only helped me to learn how to manage an Open Source community but also made me understand difficulties other people had when trying to test their software and then think of ways I could help them to solve their problem. I am also a core maintainer of [Sinon.js](https://www.npmjs.com/package/sinon), which is another very popular project among JavaScript developers and uses lots of meta-programming magic to accomplish its tasks.

Now, as a Software Engineer, I still find my experience very useful to write code that has fewer bugs in less time, and I hope I can teach you a trick or two which may save the whole world (or just your job) one day!
