Raúl Hernández López / Raul Hernandez Lopez

Senior Software Engineer - Android at Twitter UK & Kotlin lover


I would like to introduce myself as a continuous learner, apart from being an experienced Software Engineer, specialised on the Android platform & Kotlin lover, as well as a beginner speaker.

I am from Valencia (Spain), where we use to love paella and horchata, nowadays I am living, working and enjoying meetups in London (UK) and conferences everywhere.

I do love travelling when I can, listening music gigs, reading tech/no-tech books, hanging out with friends, a very cold beer or running.
