Who am I?

I’m Jefferson Bruno Silva, a Senior Consultant at Thoughtworks. I graduated in Information Technology from Universidade Federal do Rio Grande do Norte (UFRN). I also write about software engineering on my blog.

Born and based in Natal, Brazil, I’ve always been passionate about technology — from assembling computers as a teenager to creating applications for millions of users around the world.

I’m naturally curious and tend to hyperfocus when learning something new. My interests include PC Hardware, Software Engineering, Gaming, Books, and Fitness (because staying healthy is a real challenge when you’re a nerd).

Work Experience

With over 6 years of professional experience dedicated to developing web and mobile applications, I have worked remotely with clients and colleagues across Latin America and Europe. I’m grateful for the opportunities I’ve had to collaborate with talented teams and to learn from diverse experiences.
