Lucas Fernandes da Costa

Bio: Lucas Fernandes da Costa loves learning and really loves creating things.

And, as he can’t stay away from writing the best code he’s able to, you can find him on GitHub almost every day, contributing to open source projects and also helping to translate and produce content for other developers.

Lucas has 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 Lucas has moved to the United Kingdom he expects to do more talks all around the world.

Lucas has been one of the Chai.js 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. Being part of such a huge project has not only helped him to learn how to manage an open source community but also made him understand difficulties other people have when trying to test their software and devise ways to help them solve their problems. Lucas is also a core maintainer of Sinon.js, 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, Lucas find his experience very useful for write code with fewer bugs in less time, and hopes  hecan teach you a trick or two which may save the whole world (or just your job) one day!
