Inviting Tiago Danin to speak about open source means bringing in someone who contributes to the ecosystem beyond his own code: he has had documentation pull requests merged into Electron, including #11584 ('Fix URLs and Paths') and #13403 ('Improved documentation'). He has taken part in Hacktoberfest since 2016.

As a mobile developer at Idopter Labs, he also speaks to the practical side of maintaining React Native and Flutter apps: automated testing, and integrating Firebase and AppCenter. And as an independent security researcher on HackerOne since 2018, he can bring the audience real cases of cross-site scripting, CSRF, open redirect and authentication flaws found in apps.

Most of his 19 talks have been at community events in Belem, the same ones he has helped organize since 2019.

## Scope

- Mobile development: React Native and Flutter at Idopter Labs since 2022: app architecture, automated testing, Firebase and AppCenter integration.
- Security research: Independent researcher on HackerOne since 2018, with findings covering XSS, CSRF, open redirect, authentication flaws and reverse engineering on Android apps.
